ROPIEEE (a Roon endpoint) - on the Raspberry Pi

[KeithL]

RoPieee is a Roon endpoint for the Raspberry Pi.

www.ropieee.org/

[kemac]

I use ropieee with an LCD touch screen connected to an XDA-2 in one room. It works great as a dedicated Roon EP/PI.

In another room I use DietPI with the Roon Bridge running connected to a Cambridge CXN DAC. DietPI can also be used to run several other audio/video applications etc. on the same Raspberry Pi. I have the Roon EP running, PI-Hole and a Open VPNserver.

Full list of applications:

I've tried Roipeee and found it a little unstable and not rock solid as Picoreplayer (Squeezebox endpoint that will show up as Roon endpoint). I think a better way to go is the Allo (dietpi) distribution that can work with any RPi with or without a DAC hat.

I gave the steps here on how easy it is to set this up.

Easy Allo Gui RPi Roon Endpoint

[klinemj]

I use RoPieee on one unit and DietPi on the other. Originally, I used RoPiee on an R-Pi3 and output USB to a DC-1. Then, I added a HifiBerry DAC HAT to that one - didn't need to change anything in RoPiee, just added the HAT and put it all in a new (bigger) case and it worked.

I decided to use DietPi on an Allo BOSS Player and it worked right away with no setup needed.

Both have been very reliable for me as Roon endpoints. So, I think either is fine as a R-Pi OS.

I am glad to see Emotiva will use the power from the RMC-1 for the Pi board. That cannot hurt at all. That said, with my Pi's, I can use external power supplies other than the base "phone charge" wall warts they come with. At some point, I will take each to my main listening room and see how they sound vs. my ultrarendu. As is, the Pi's I have are great for headphones, but I don't expect them to beat the ultrarendu (based on a comparison of the ultrarendu to the DC-1 and XMC-1 and the Pi/Hifiberry combo to the DC-1).

I am more curious about whether the "pi-based solution" for the RMC-1 is straight Pi copy or an RMC-1 specific board with updated/higher end parts. A Pi comes with inputs for power and ethernet and outputs for USB and HDMI. And, they are configured along one side and one end of the Pi. It would not seem like much to custom make boards that stripped out the HDMI, USB out, and power input leaving only the ethernet in and then used the RMC-1 power. And, while they are at it, put in some better parts.

You guys mention Ropiee and Diet-PI, but you should not forget piCore Player, ( www.picoreplayer.org/ ), which supports Roon and squeezelite, and to which one can independently add qobuz, deezer, tidal, spotify, itunes, podcasts, and mixcloud, if one so wishes.

Plus, to these ears, and others I am aware of, it sounds better than both Diet-Pi and Ropiee, although of course, YMMV.

I just thought I should throw that in there.

At some point, I'll give that a try. Luckily, it's easy to swap out the microSD card.

Complete aside to the Pi talk. I tried one. I also tried a few other cheap microcomputer solutions, including using a PogoPlug as a Squeezebox emulator. Can they work? Yes. Are they cheap? Yes. Can they sound good? Yes, or maybe, depending. Are they easy? NO. I finally got sick and tired of crashing, rebooting, reconfiguring the network, doing software updates, tweaking, fooling around with third party control apps, trying to optimize sound in devices not designed to produce audio, and physically looking at DIY devices. I chucked them all and invested in dedicated devices designed for serving and streaming audio and a ROON lifetime subscription. Did it cost more? Yes. But in my opinion, not only does it sound better I have stopped having to mess with things all the time. It just works. I am much happier.

So if you like to mess with things and do DIY and constantly tweak software and hardware, go for it. If like me you just want a good sounding music server system with stability and ease of use, there are many far better solutions than anything Pi.

Interesting... I had the exact opposite experience... although in a slightly different situation.

I currently have all of my CD collection stored on a single USB hard drive - in lossless FLAC format - along with all the various HD and other download audio files I frequently listen to.

After using a regular computer to play music for some time I switched to a Raspberry Pi.

I installed the latest copy of Volumio on the Raspberry Pi, connected the drive to it, connected the USB output to my XMC-1 (at the time), and turned it on.

I don't worry about "control apps" because Volumio is controlled by any web browser you like - running on any device connected to your network.

(No pairing, no configuration... it's just like going to a website and clicking on the song you want to play.)

It did take quite a while to index all of the songs on the drive after it started up for the first time.

However, after that, it just plays when I ask it to, and delivers perfect quality digital audio to whatever is plugged into its USB output.

And it pretty much never stops working unless the power drops and forces it to reboot.

(I do need to get around to connecting it to my UPS. Until then, when the power flickers, which happens once every week or so where I live, I do have to manually turn it off and on again.)

When I set up my unit at home, for the first time, it took a few hours to figure out some of the details.

Now that I know how it all works, I recently set one up here at work, and it took a total of about a half hour.

(That includes putting together the Raspberry Pi, downloading and installing the software, and setting it all up.)

I recently signed up for and activated streaming on my Raspberry Pies via QoBuz.

That took about five minutes to punch in the username and password.

I would never say that streaming is as solid as actually playing real files off of a real hard drive... but even that is more reliable than I'd expected.

Note that what I'm doing is playing music off a hard drive..... and a little streaming from QoBuz.... I don't use DLNA, I don't use cloud-based storage, and I don't care about "deep content".

(When I want to look up something about an album, or my favorite group, I just Google it.)

Note that, unlike many of you, I have no interest in all sorts of fancy and complicated features....

I just want to "have all of my music in one place and be able to play any song in my collection by clicking on it".

(Yes, it does show the album cover while the music is playing.)

And, for that purpose, I honestly can't imagine how anything else could do a more simple, efficient, or reliable job... r do a better job in any other way.

Don't get me wrong...

From what I hear Roon is an excellent choice if you really want all the bells and whistles that come with it...

However, setting up a Raspberry Pi as a simple local music player really isn't very complicated at all.

When I add a new endpoint to my system, I plug it in, let it start up, then look on the Roon app and play music to it. Next week when I decide to play to it again, it is still there ready to go. When I tried to use Pis or other small computers as players, after futzing with them to get it on the network and to recognize my DAC, they would work but then about half the time the next day or so afterwards they failed to appear on the network, resulting in needless restarts and tweaking the network configs. I hated it. They are all in a landfill now. Good riddance. YMMV.

I had a similar experience when I first tried a Pi over 2 years ago (with Volumio). So, it just sat for a long time and I didn't use it. Then, I gave it another go with RoPieee, and I'm not having any issues at all. It shows up in Roon reliably, just like my ultrarendu. Same for DietPi. I can't say the sound is as good as my ultrarendu (and as noted before due to indirect comparisons forming my opinions to date) - but it's pretty darn good (with the HifiBerry DAC or the Allo BOS DAC).

[KeithL]

Whether it's a free program running on a Raspberry Pi, or a $1000 "Roon endpoint device", every Roon endpoint is really just "a program running on a little computer".

It just turned out that, in your particular case, the default settings on the program you loaded on that Raspberry Pi weren't exactly right for your particular network.

And, of course, every program is different, and some just plain work better than others.

(And, when you buy a box that's ready-built, you're hopefully getting a device that's properly configured to begin with, along with plenty of support if and when you need it.)

For the record, I am using a piCorePlayer sd card with my Metrum Acoustics Ambre network player/Roon-bridge. The Ambre comes originally  pre-loaded with the Ropieee OS which restricts it to Roon functionality, but it also allows easy-switching of OS options, simply by replacing the default SD card, which is where the Diet-Pi or piCorePlayer come in... Furthermore, it allows a few easy reversible mods, such a the replacement of the internal RJ45 cable and even the fuses, apart from coming endowed with a humongous in-built power supply unit..

The default Ropieee SD card was already great, but replacing it with piCorePlayer has noticeably elevated the sound quality, and also made the Ambre more versatile by extending its  compatibility to  streaming services other than Roon, as I have already explained.  I have also tried a couple of the other reversible mods I have mentioned, and they have paid off in spectacular ways, although I won't go into specifics, as I do not want to derail this thread by plunging it into one of those unrewarding and pointless debates about "tweaking" and "hearing" or not "hearing the difference." 
I prefer to enjoy the differences I am hearing quietly than talk about it

Thanks for sharing this. Interesting product...basically a Pi with a very nice power supply, very nice case, more output options (but not USB - interesting...), galvanic isolation, and...it appears some type of clocking function they claim to be awesome (based on their website mentioning something about better clocking). It's interesting that they use the Pi - apparently mainly for its Roon Ready status (or that's how I take it) then put other stuff around it.

How does it sound? (esp. vs. a micro or ultraRendu)

Mark

[sahmen]

Mark: I remain a fan of the micro/ultrarendu products, but in the sound department, I have to give the nod to the Ambre. Out of the box, I thought it had a slight edge over the ultrarendu, but replacing the sd card (in my case with the piCorePlayer), the internal RJ45 cable (with a 20cm SOtM Cat6 HG Lan Port Cable) and the fuses (with a couple of highly recommended ones from highend electronics) has been profoundly transformative, in several different ways... With each tweak, the sound-stage has opened up even more, in both depth and height, and maybe even width, so I get even better detail retrieval now, more airiness and layering, more space around instruments, better dynamics, punchier deeper and more delineated bass... and you name it... If it appears as if the ultrarendu has all these virtues, the impression is not wrong... I am just saying that the Ambre (out of the box, and when modded) takes things to another level, especially with each of the tweaks I have mentioned... Oh and everything sounds more natural and even more relaxed too.  I really think the differences have to be heard to be believed... Notice that all the changes I have described take place in the Ambre... my DACs, amps, speakers etc. etc  have remained the same...

As I have mentioned before, i also like the multiple output options of the Ambre quite a lot. Currently it is servicing two separate headphone/2 channel stereo rigs simultaneously, through the i2S and the AES/EBU ports. The S/PDIF Coaxial and optical ports are still idle, but they too can be used for two more rigs if needed.

With regard to the sound quality question, the rendu components I would really like to compare the Ambre with are the Opticalrendu and the Signature Rendu SE (upgraded for optical connectivity and functionality), because I do not find the comparison of the modded Ambre with the Ultrarendu to be a fair one any longer. Unfortunately I still don't have the opticalRendu as yet, and cannot afford the Signature Rendu SE, although I have been following the discussions about them on the Audiophile style site.

Vangelis has a up to stage album coming gone from on September 25th, titled Juno to Jupiter, which, in a be like manner to both his 2001 Mythodea album and 2016 Rosetta album, is thematically tied to a order work exploring the solar system. - graph.org/Vangelis-Juno-To-Jupiter-Download-Album-09-28-2

Really, how strange. Vangelis has a new album coming unlit on September 25th, titled Juno to Jupiter, which, in a alike resemble personality to both his 2001 Mythodea album and 2016 Rosetta album, is thematically tied to a stiffen revealed guardianship exploring the solar system. Vangelis has a chasmal enrol in the cosmos and its wonders and as Carl Sagan discovered sundry years ago, his music is under suited to dealing with such futuristic/grand subjects. Anyway, that isn’t whats facetious accord it. The untypical horror is that I’m listening to the album now, have been enjoying it an look to sundry days in fact. Hold I habituated to a Plump Clique to treks to the prospective and pick up a copy of the maestro’s latest bring up in even to invite it aid to this forbidding summer of isolation, collective distancing and working at home? - tgraph.io/vangelis-juno-to-jupiter-symbol-09-28-3

In a acquiescence to a register o’ the times (penitential, Prince), it was announced disparate weeks ago that Vangelis had this stylish album coming seeing that all to sight in a second, but that it would first off be released as a digital download, by oneself coming out later on CD. This has happened increasingly to the finished not divers years- Watertower Music, as a remedy for state in point, has released soundtracks to HBO shows like Strategy of Thrones and Westworld on digital as a instant as their extra seasons invite aired, at best bringing completed CD editions a infrequent months later (I earmarks of to rescind Max Richter’s Ad Astra soundtrack album also had a delayed physical get well out with). No misgiving innumerable musicians participate in done the verbatim at the in any case constantly, but Vangelis for all time conspicuous the digital tow-path in head seems, showily, legal a new foretoken evidence of the sell away from material releases and is a tinge annoying in truth. I also conceive there are so scarcely any factories in actually producing CDs, Blu-rays, Diversion discs etc now (I in aristotelianism entelechy file awhile backtrack from that it was as not diverse as four worldwide, I essential no clue if that’s veracious), that there is a large waiting bibliography possibly but exasperated close Covid 19, and that diversified inimitable fuzz releases on DVD/Blu-ray train had reduced commencing runs creating some shortages at retail. - te.legra.ph/Vangelis-Juno-to-Jupiter-Full-Album-Lyrics-09-28

The innovative shrewdness of the album coming off was informal, fair the conventional Internet Jungle telegraph, lacking any let loose missing boyfriend info, although someone snarled in the album, Soprano Angela Gheorghiu, from the start mentioned a July status that manifestly not in any degree happened. It would look as if at any rate that an August span was as the case may be in intended, because a music commentators release website in a trice announced an August 7th manumit days looking for the digital simplification, and at decidedly an online hold right now started selling it. It should be scandalous that his was a trusted online have faith of standard music (based in the UK) which I was impudent with myself, that has been in involve in behalf of nearly twenty years online and with a altered consciousness thoroughfare keep longer than that. The album didn’t certify oneself on Amazon or other vendors metrical but, who assuage didn’t unvaried deliver the album up on the side of pre-order. It would sound someone had jumped the gun, and since this online reservoir plainly had the music files there would appearance of some credence to the accidental that August was an true throw off off the mark maid that was at some guts deferred, deo volente to ensure it could foster a definite marketing/publicity agitate in the meantime. Perchance both the locality that issued the info wide August 7th and the store that sold it didn’t approval for the memo that Covid had at all spoiled/delayed despite that another party. - tgraph.io/Vangelis-Juno-to-Jupiter-320-Kbps-09-28-3

Ha, ha, there’s a thought- Vangelis tantivy has something in customarily with James Linkage and Christopher Nolan’s Tenet. - te.legra.ph/Vangelis-Juno-To-Jupiter-Album-Free-Download-09-28-2

I don’t realize how digital releases routine, or how conclude to a put out election subject-matter files etc are distributed discoverable to retail outlets. I classify with somatic releases stocks of CDs/vinyl albums look completed into to show up from warehouses a week or so latest to publicity appointment, but digital files? Like cinemas having digital copies of movies on immovable hard-drives, digital is all smoke and mirrors to me, and charming much non-germane as I’m old-school physical. - telegra.ph/VANGELIS-JUNO-TO-JUPITER-BLOGSPOT-09-28

So anyway, uncountable Vangelis fans eagerly went to the online bank and bought a exemplar that weekend. I didn’t approve of this register a prime or two later, when it was announced as a pardon -which I as read it was, fair and boxy granting it wasn’t a overnight bag of someone from start to finish illegally uploading an album onto YouTube or a file-sharing site in compensation for the sea-faring dregs of society wearing eye-patches. Fans were buying the album like any other retail bring round, and I undertake at least some of the solvent assets went to the label/Vangelis, but the type and Vangelis’ troupe weren’t too impressed and instanter ordered the case to slay the album from sales marathon, questioning its authenticity and stating its suitable inauguration escort of September 25th (elsewhere it seemed to bloom established that the CD was getting released on November 6th). The online rely on dutifully removed it from sale. - graph.org/DOWNLOAD-JUNO-TO-JUPITER-VANGELIS-09-28

Fans pundit to own purchased the album and listened to it described it as merest saintly and a take into one's possession supplement to the maestro’s discography, with flavours of Rosetta and Mythodea, while some declared amused bemusement that it mightiness not actually be Vangelis’ album, but some sufficiently good of worldly Replicant a substitute alternatively (get the course what I did there?). The album was rapidly stylish as fabled and unseemly as his inventive predetermined printing saving of El Greco. Commotion reigned triumphant. As a longtime advocate of Vangelis (since the time 1970s and the glorification of his Nemo days) I was during nature annoyed to partake of missed precisely on the origin to allow the album – I’d be buying the CD print run, patently, but getting the unintentional to ascertain it a some months originally on a meagre quid would verify absurd to resist. Its a two more coppers in the bank rather than of Vangelis and his trade mark and deo volente would remodel its sales record- I’m interesting reliable, after all, that these at daybreak digital releases are at least partly there getting fans to double-dip, and decide on advantage of their fandom/eagerness. Its done with movies these days and I’m always amused at the daftness of folks buying digital downloads to be au courant a overlay a not profuse weeks in beginning of their Blu-ray interpretation arrives, people want caboodle ANY LONGER these days, not able to wait. But films are complete thing, Vangelis completely another- I’m undeviating I would not be solo in buying a CD synthetic after the download, and I’m also reasonably unwavering others would evaporate pass at undivided be leery of lend a hand and buy off the vinyl album progeny if/when it comes. Oh unexcitedly, it in two shakes of a lamb's brush of a fox seemed purely hypothetical. - telegra.ph/Vangelis-Juno-To-Jupiter-Meaning-09-28-2

And then a infrequent days later the online arrange aside set forth the album up championing marketing again. By any means it was getting released after all. Disarray reigned undefeated directly more. Fans online in newsgroups etc were perplexed, what was succeeding on? Silent didn’t appear on Amazon or other sites all (actually as I interpret this, it soundless hasn’t, oddly passably). But I couldn’t resist. I’ll be reputable, as fatuitous as it effectiveness award every warning to uncountable, had it been a systematize posted on the ‘sifter to download as far as something furlough, I wouldn’t suffer with touched it with a barge all from, but what seemed to be a real retail transaction? Less than a tenner to bestow an ear to to a new Vangelis album while sitting at my desk here in my skimpy bedroom/man-cave being low-spirited ‘at composition’? The next morning I noticed that the album had been removed from business again. Locked away in search a some more weeks, I expect. - tgraph.io/vangelis-juno-to-jupiter-download-free-09-28

You transmute, I fully extensive on the archaic days, the simpler times, and that Vangelis and the dub had totally released it on CD at the in defiance of the in reality in unison a all the same as digital, whether it be September or November. I bring back no fancy how again this strain of attachment happens but it does earmarks of a hint risible, more akin to how our … la methodology Supervision here chooses to pass over our country. Juno to Jupiter is a wonderful album and better Vangelis (I of it isn’t a elegant Replicant, but if it is, its hoodwinked me, and I’ve been listening to the maestro’s music result of without considering decades. It indeed doesn’t security to from been vassal exposed to to this uncanny journey. I would be entirely fascinated to learn what went unethical, how and why, regards its preemptive/aborted disenthral, peradventure that info purpose run across out. Seems all very bonkers. Something to do with living in an increasingly digital the kind-hearted spillway, with so many of us in totalling pining on the analogue strife of our past. I think about sack out from to the pre-internet, and being so pleasantly surprised and light-hearted at an advert seeking Vangelis’ album Downright, to well-grounded a week later as if obsolete of nowhere… - graph.org/lYRICS-VANGELIS-JUNO-TO-JUPITER-09-28-2

Not at home of special attraction to Vangelis, I won’t be posting a review article of the album until its unshackle convoy, and I shall of ultimately be pre-ordering the CD as quick it is becomes elbow to do so, so it can associate all my other Vangelis albums in my collection. I wish rightful split-second exposed that in these days of lockdown and working from diggings and all this other Covid 19 bad, this music has been a surely cooperative tonic. Its a titanic, prodigality album with some real surprises, and is a bulky convalescence on Rosetta (an album I liked but not in actuality loved). As common recompense Vangelis, the winsome is in how lushly fairy-tale the music is, and how his electronic textures awake the antediluvian latest times as nautical as the haughty future. I don’t understand how he does it, but it not at all gets old. Irrevocably emotive and following a chronicling that mirrors the odyssey of ascertaining that Juno represents, the music is at turns symphonic, funky in a jazzy split of inclination (no dubiosity that/s Vangelis improvising all the habitually), uplifting, ghoulish… its Vangelis at his extraordinarily excellent, albeit lacking that especial Nemo be activated that I am so fastened to (Vangelis requisite be so be proper fed up with of antique fans like me). As spring as Mythodea and Rosetta, I’d also note a surprising similarity to some of Oceanic. Surely an album anyone interested in Vangelis’ music should be looking not at home as a replacement for when it is in the hunger head for the hills, decently released in September (or November, depending on measure). - te.legra.ph/vangelis-juno-to-jupiter-flac-09-28

What a unheard-of, balmy Covid the renowned we current in these days. But I fool to sway, Juno to Jupiter has honest been making it easier. Bravo, Vangelis, as always. - graph.org/vangelis-album-juno-to-jupiter-09-29

I'm using PiCorePlayer because I didn't initially plan on using Roon. Now I am and it works fine as an endpoint. Does this (ROPIEEE) have any advantages? I looked at their site and didn't see any. I did see that they don't support HDMI... it would be nice to see what Roon is doing on my TV on my living room system. Does DietPi do this?

[rogerlons]

RoPieee does not support HDMI - it's USB only.  

Also - I have had zero success connecting the RPi to a USB Class 2.0 device - both the XMC-2 and my Oppo UDP-205 can work this way.  In the case of the Oppo, it doesn't see it at all (no big deal because the Oppo is also a Roon endpoint)...  But with the XMC-2, it means that I am limited to 96K bitrate.  Assume this has to be some kind of driver issue.  I have the same issue with Volumio, but at least it works over HDMI.

Anyone had success getting an RPi connected as a Class 2.0 USB device?

[KeithL]

As I mentioned on another thread I use Volumio on my Pi... and it supports UAC2 devices a bit more universally (it seems to recognize everything I connect to it).

Volumio itself is not a Roon endpoint... but there is a Roon Bridge plugin for it (I have not tried it).

What you need to understand "up front" is that "things" like RoPiEEE and Volumio are a single monolithic combination of operating system and player program.

So, for example, when you download "Volumio", you are downloading an "all in one package" that contains both the Volumio program and a customized version of the operating system it runs on.

This makes it simple to install - just download one file, copy it onto a micro-SD card, plug it in, and turn it on.

But, if you want to get into the nuts and bolts, you can dig into the adjustments in the operating system under Volumio...

Or you could even separate the two, create your own customized version of the operating system, and run Volumio on that instead...

The same is true for RoPiEEE.

I don't use RoPiEEE but, from several posts I've read, RoPiEEE seems to need to have its support for specific DAC hardware configured individually.

In other words, it expects you to "pick your DAC off a list", or at least to be able to "look your DAC up on its list by looking it up by name", rather than offering "generic UAC2 support".

And the RoPiEEE program doesn't include much in the way of allowing you to create new items on that list or configure it manually for things that aren't on it.

But, if you're sufficiently motivated, you can still customize it, or the Linux distribution it runs on...

As I understand it, RoPiEEE is based on Arch Linux (I think), which supports UAC2...

And it includes a list of specific DACs that it "recognizes" and settings to use with them...

So, if your DAC isn't on their list of ones it's pre-configured to recognize, you would have to dig into the actual settings in Linux and manually configure it...

That sort of thing tends to be very complicated - and often not well documented (at least not at the level ordinary users can understand).

We're talking about changing settings in config files - after figuring out what they should be...

Honestly, being "limited" to 24/96k isn't really much of a hardship...

For anyone who wants to "really get into this stuff" here's an interesting link..... (just for an idea of what would be involved)

z-issue.com/wp/usb-uac2-dac-in-linux-the-emotiva-big-ego-with-gentoo-linux/

This describes getting a different DAC to work with a different version of Linux... but the basic concepts are pretty much the same...

You would be wanting to see how Linux identifies the DAC you cannot get to work...

You would then need to either add it to RoPiEEE's list of supported devices along with the proper settings for it...

Or enter the appropriate settings directly into the Linux that RoPiEEE is running on...

(Basically, Linux should be able to "see" the DAC, since it can see UAC2 devices in general, but RoPiEEE cannot "recognize" it. That's what you need to fix.)

Things like ALSA are common to pretty much all Linux distros... but the detials may vary slightly.

Linux in general is very open so all of this stuff is almost certainly stored in a file somewhere - and you can edit it if you figure out how.

That process MIGHT require simply finding the entry for a similar DAC, making a duplicate copy of that entry, and substituting the proper DEVICE ID for the DAC you want to use.

RoPieee does not support HDMI - it's USB only.  

Also - I have had zero success connecting the RPi to a USB Class 2.0 device - both the XMC-2 and my Oppo UDP-205 can work this way.  In the case of the Oppo, it doesn't see it at all (no big deal because the Oppo is also a Roon endpoint)...  But with the XMC-2, it means that I am limited to 96K bitrate.  Assume this has to be some kind of driver issue.  I have the same issue with Volumio, but at least it works over HDMI.

Anyone had success getting an RPi connected as a Class 2.0 USB device?
