Anyone else using (or trying to use) Volumio on a Raspberry Pi3 with USB on your XMC-2? I had previously used RuneAudio with my XMC-1. I had no problems whatsoever. After getting my XMC-2, I was not able to get it to work. So I switched to Volumio. No problem. It worked right away. Then about 2 weeks ago I got this status when trying to play anything: I updated Volumio. I reflashed it again with the latest image. Half of the time it does not see the 'Emotiva RMC-1' anymore. If it does, I get the status in the pic above. When I restart the Raspberry Pi, I here the relay in the XMC-2 click. I'm running firmware 1.8 (because I'm afraid to goto 1.9). The end result: I cannot listen to my FLAC files on my stereo. I thought maybe it was Volumio, but I am leaning on the XMC-2 since i still have other problems. Anyone else have this issue? I searched your error on google, and it looks like the problem is the Pi...a lot of threads about that error dating back 8 years even. Search on the various Pi boards for a clue. One I found did suggest power supply issues as was just noted by petes. Mark OK, I replaced the Pi and everything es beuno. After reading KeithLs reply, I will have to check the USB plug/unplug issue as well (although I was removing and restoring power from the pi). Thanks everybody for the help! |

Itphoenix and KeithL,
I am having similar USB audio problems, this is just not a Raspberry Pi problem, it is a XMC-2 problem. I have an Auralic Aries Mini streamer which I had connected via USB to my XMC-1 for several years. It worked perfectly 100% of the time from day one.
A month ago I traded my XMC-1 for a XMC-2 and now have the same problem described by Itphoenix, my XMC-2 is running firmware version 1.9. If I reboot the XMC-2 and my streamer several times I can sometimes get USB audio to work, but then after several days it fails again. The error message from my streamer software is “Unable to open output device: Emotiva RMC-1”. This is with UAC-2 turned off (the XMC-2 default).
The XMC-1 used the C-Media CM6631 chip which worked well, I believe the XMC-2 uses a XMOS xCore-200 USB chip (KeithL please confirm). KeithL will this issue be resolved in the next firmware release?
Forum members, if you are having USB audio issues with the XMC-2/RMC-1 please reply, so we can see how wide spread this issue is.

... Forum members, if you are having USB audio issues with the XMC-2/RMC-1 please reply, so we can see how wide spread this issue is. Semi regularly (about once a week) I play ALAC files from iTunes and Audirvana on a Mac mini via USB. On one occasion when I switched back and forth between USB, TOSLink, and HDMI, the RMC-1 became unresponsive (but continued to play). In general, my mini to USB connection has been reliable. |

I'm running a Pi v3 - with Volumio - and an RMC-1 - and it acts the same way. If you power down the RMC-1, then restart it, the Pi no longer recognizes it as a valid USB device until you reboot the Pi.
(And I've noticed the same thing on a PC running Windows 7.)
It would seen that, somewhere along the line, the "USB hot plug capability" isn't doing its thing quite right.
I have discovered that you DO NOT have to reboot the Raspberry Pi. If you PHYSICALLY unplug the USB cable between the Pi and the RMC-1, then plug it back in again, it works again WITHOUT rebooting the Pi. (The USB interface knows the difference between a device that's turned off and a cable that's physically disconnected.)
Note: There are companies who make a USB cable with a built-in switch for manually disabling connected devices like USB drives. I tried one of these, made by someone called RiiTop... and it DID NOT work.
(I assume it disconnects the power but does not physically disconnect the data lines.)
Along the lines of other good thoughts, I'd try plugging the same USB cable into a laptop if you have one handy, see if it recognizes the XMC consistently and can play through it OK. I hear the faint relay clicks as well when USB connection transitions on/off, seems normal. I also built a brand new Pi 4b with RoPieee (Roon Bridge) using USB a couple weeks ago and while it generally works, so far nearly each time I power on the XMC-2 (from low power mode) I have to then reboot the Pi or unplug/plug it back in for sound to play. Haven't troubleshooted that too much yet. I didn't recall having that issue when initially using laptop USB so maybe it is something about the Pi (which is running latest USB firmware 000137ad for the 4b). Still testing. Good luck. Same problem with the RMC-1L and an Auralic Aries streamer. After every standby and wake up of the RMC, I have to either reboot the Auralic or disconnect and reconnect the USB cable. Sometimes flipping the USB mode in the menus from UAC1<>2 also fixes it. |

You guys better go back to a XMC-1, mine is connected to my Mac Mini via USB and zero issues, I'm glad I'm 1080p and non Atmos as it seems I can keep my sanity in check better  Chad |

I switched my output to HDMI Output 2, and my Roku came up quickly. So far so good. I'll keep testing switching between inputs and see how the XMC-2 behaves. So far it appears switching my HDMI output to port #2 has solved my issues. Especially the Roku is consistently connecting when I select input 4. The recommendation I got here for the fix is much appreciated! Finally got around to testing my Sony 3D BluRay player on HDMI input 3. Player menu came right up the first time and worked flawlessly with the XMC-2. I tested with Avatar 3D disc. Indicated audio content was DTS-Master Audio 5.1. The 3D picture was spectacular on my LG OLED tv. So all my inputs work well now, and are consistently connecting with my tv, etc. I'm very happy with the upgrade to the XMC-2. All we need now is to get our Dirac software. |

I'm not sure if I just missed it or what, but is there any clear documentation on height/width speaker configuration? Questions I have:
1. What do the Dolby Enabled option mean? Is that if you bouncing modules on top of your main and/or rear speakers?
2. How do you add three rows of top speakers? I only see front and rear height options. Either of them can be set to top, including middle. But what if I decide I want front, middle, and rear top speakers?
3. For the width speakers, what is the bi-amp option?

IT's a little disappointing that you have to give up sub outputs if you want three top channels. It would have been nice to see the width channels be assignable. But, I'm guessing we're talking about a pretty small % of the population that will need that level of flexibility. |

But, I'm guessing we're talking about a pretty small % of the population that will need that level of flexibility. Np. The XMC2 is a 9.1.6 processor. But it gives us the flexibility to go 9.3.4 using the sub outputs. I agree with you about maybe having a little more flexibility with the front width outputs since a lot of people don’t use it. Then you could go 7.3.6. Maybe after all the issues are fixed and Dirac is released, they can work on that flexibility (if it’s even feasible). But I’m doing 9.2.4 and don’t plan on adding the middle ceiling so for me the need isn’t there. I certainly wouldn’t want Emotiva wasting their time if no one uses it or if like 1% would use that configuration. |

Using only the Center Subwoofer Output into a miniDSP 2x4 allows for 4 subs on the output which can be individually calibrated by using the built-in matrix for turning on and off each sub. The basic miniDSP is around $100. I just bought one this week, so I'm just learning about it. There are many Loungers using these and are very knowledgable about them. |

I have 2 subs and don’t plan on buying anymore unless it’s another PB16 to replace my SB13. I am hoping Dirac bass management that’s going to cost $349? will blend my subs in the rest of my system. So maybe end of 2020? I’m hopeful. |

So maybe end of 2020? I’m hopeful. I've got 3 subs, but only use two right now. The third is a smaller Rel that I may decide to use in the back for movies only. There's a couple reasons for getting the miniDSP. First, I got it because I need to be able to measure my subs WITHOUT the XMC-2 to be able to integrate the subs with my Mains while using the speaker level connections. The main point being that I am learning through looking at the measurements where to place the subs and how to orient them (angled is much better in my room). This can be done without the miniDSP but it's a lot easier with it. Now, the miniDSP can't help with filters using the speaker level connection, unless I use a high to line level adapter (not sure I want to do this), so this is mainly to aid in placement. Luckily, in my room it seems that what I've suspected is true, that there isn't a big problem with frequencies below 100Hz. My Mains have their own ARC built-in which is specifically for the woofers up to the crossover point of 300Hz, above which is where the electrostatic panels take over the rest of the way. Subwoofer and Mains integration is mainly aimed at two channel music listening. The second reason is simply that I have a hunger for learning about all this measurement stuff. Playing with speaker placement and orientation is pretty interesting. DIRAC will be useful for calibrating my system for multi-channel usage. For two channel I've never been able to integrate subs with electrostatics via a preamp processor and be happy with it. I've always been happier using the speaker level method. I emailed Dirac this week to ask some questions. Similar to the famous Microsoft Helicopter Joke, they chose to be less than helpful with their reply, except to say that they changed the name of their bass software and now call it Dirac Live Bass Control. I "think" this is available now, but they weren't clear about this. I "think" it will cost the $399 that we have been told in the past, but they said this is up to the manufacturer, not Dirac, as some include it and others charge extra. |

I have a 2x4 HD that I bought because the way Dirac (or maybe XMC-1 + Dirac) handled multiple subs wasn’t correct. I’m hoping those problems are behind us with this generation, and I can use multiple outputs. That will be particularly helpful if I finally decide to build a BOSS platform, and can make sure not correction is sent to that sub channel. I do plan to keep the 2x4 HD in the picture because I use it for BEQ. |

Aha so that explains the name change in a recent Dirac article! I'm still curious to see how Emotiva implements standard Dirac 2.0 for bass management and multiple subs. It's very tricky, and hence taking it outboard to a miniDSP worked really well for me when I had the XMC-1. Let Dirac see "one sub" and do the time and gain alignment in the miniDSP. Bass management happens before PEQ/Dirac. Correction of each channel in the context of its crossover and combined response .... not sure how to do that well. The other thing I really like is having control in the miniDSP app to turn each sub off/on, invert polarity, etc. while doing individual measurements. Beats running back and forth around the room. REW on one screen and miniDSP 2x4 Advanced on the other. And BTW .... I found in some measuring and tweaking the other day that PEQ filters in miniDSP can affect phase, and hence result in tweaking time alignment. Ends up being an iterative approach to getting timing and phase all playing together. |

Hey guys this is prob stupid for many of you but relevant for me. Is there any way to switch to ARC input using a harmony remote? I ask bc I use my HTPC for gaming and Plex on HDMI 1 input. When I want to watch OTA TV I need to set it up to switch to ARC. Easy solution would be to select the activity on my harmony remote and be done but I can’t figure out how to assign it to arc. I’ve setup the XMC2 for arc input on turn on but currently the only work around I have it to adjust the command to turn off the XMC and back on so it switches to arc. Anyone else have a better solution?
Edit: oddly I deleted the receiver and added it again and now arc is listed. Hmm guess it’s solved lol
Edit2: actually still doesn’t work. Won’t allow you to select arc as an input but under the device itself it will show arc button. No way that I can tell to assign it to the start commands either. Weird

Here is my fix for anyone in the future that wants to use the harmony remote to control the XMC. Not the most ideal solution for such a high end piece of equipment for sure but at least it works until emotiva can get things sorted out. First step is going into the XMC settings menu and setting button 8 as the selector for Arc. Arc doesn’t lock on (for me at least) if the input is not switched to something different then back once the video is stable so you will see that I switch to a random input pause and switch back (any will do I chose 7 for no reason other than it’s close to 8). I also played around with different delay settings and while less delay worked it wasn’t very reliable so I increased the delay until I got very reliable results. Hope this helps someone as I wasted about 3 hours messing with this lol. I use the same delay and input switching on all internal apps and OTA tv settings.  |

Hi guys
I have a question regarding the Dolby surround upmixer.
Currently I have a 9.1.6 setup.
Previous I had a 7.1.2 setup running off a Yamaha aventage RX-A2050
With the Yamaha when I played games on my switch (Pokemon sword for example) or any game on the Xbox one/watched any movie that wasn't in atmos (5.1 or 7.1 content) It would be mixed into all channels and sounded great.
Since Getting the XMC 2 I've noticed that the DSU will only play sound from
Front L/R
Centre
Top Front
Top Rear
It won't play any sound from
Top Middle
Side surrounds
Rear surrounds
Front wides
Now I am aware the DSU doesn't support front wides but I'm unsure why the same content on the XMC that I played on the Yamaha has stopped playing out of the Surrounds and Rears (not sure if Top middle is ever used as I didn't have those before)
Is there an issue with the processing on the XMC that anyone is aware of? Running FW 1.9.
I should mention any Dolby Atmos (TrueHD or DD+) content appears to work fine on all channels.
I also noticed when Using DSU on Tidal the XMC doesn't use the Sub (set to LFE with Fronts set to Full range) whereas with the same config on the Yamaha the sub was used in Tidal music on Surround mode (direct 2 channel only use L/R as they should).
