Another item, or at least variation of an issue to add to my list. While streaming Game Of Thrones using the HBO app on the AppleTV, at 49 minutes I had the buzzing audio issue return. I had been experiencing audio dropouts, but it had been quite some time since I had the buzzing issue. All my issues have been reported to Emotiva. Perhaps they will have a suggestion for me to try.

Just to clarify my comment should have read that Emotiva has no way to rip UHD discs hence the suggestion for BD titles with ATMOS to replicate the issue. There may be another possibility which would have to do with the sheer volume of data in ATMOS tracks and the size of the data packets creating buffer issues over the network. Only way to test that is to try it on another processor and see if the problem persists. I use a Shield with Plex and it plays everything... I still need to test the setup with the RMC-1 but with the Denon 8500 I had no issues with anything coming from the shield. I also used it for Netflix, Amazon and YouTube. I've also used an Xbox 4k but they don't do the HDMI pass thru so their audio like many of the other streamers is limited to compressed formats

I’m running KODI 18 on my Shield to stream. So we know that ATMOS streamed through the Shield on the Denon 8500 was clean with no audio dropouts. The next question will be whether or not you will get the dropouts from your NAS via PLEX and what happens if you install KODI and try it.

So I did a quick test, only hooked up the RMC-1 to the DR3 (LCR) with the Shield and Direct TV. Using Plex and Youtube things worked as expected (TrueHD, DTS HD, EAC3 etc) with two exceptions, both music related... 1) Before I found out about the setting for 2.0 vs 5.1 I set the unit to Pure to not have it up mix the stereo audio. This caused the shield to drop down to 1080P and the only way I could get it happy again was to pull the HDMI cable and reboot the RMC-1. I understand why this might cause an issue but it seems odd that I had to do a full reset to fix it... 2) With any of the PCM sources (Shield is converting the MP3/DSD etc to PCM) I would occasionally get a skip. I first heard this on Youtube but then verified the issue with media from the local server.
Overall I think the unit definitely sounds better than the Denon, it seems to have better imagining and sounds a lot more dynamic. This is with no changes to the amp, speakers or wiring. I'll be honest its really hard to do an AB comparison as the Denon fed the amp with unbalanced vs balanced but it does seem noticeably better.
Where I'm not thrilled is with the remote, its really heavy, not backlit and I don't understand why they put the buttons on it that they did. Hopefully I won't need to use it that much... I will also need to figure out a remote extension solution. I tried using a set of emitters and the rear plug with no luck in either scenario. I did see a post about turning off the settings in the menu but I hate to go too far with that as I don't want to lock myself out... I still need to build the rack so this is a longer term problem but the good news is that for the most part its working.
One other item is that it doesn't seem to do any conversion of the video signal, this is both good and bad...
BTW Both HDMI inputs were still set to 2.0 but I did upgrade the firmware to 1.3 from USB (easy and worked as expected), in theory the Direct TV DVR should be set to 1.4 as its very old..

SACD DSD Post 2 of 2: Tried SACD DSD digital audio output through HDMI1 on the oppo95. OPPO95 setup to bitstream and DVD-Audio. Not sure if it's a correct setup because: 1. During play back, RMC-1 Info had audio as PCM 2.0, 88.2kHz, 24bit. 2. During play back, OPPO has output as SACD PCM (not DSD ... not sure why). If this is correct setup, then everything worked the same as before. No issues. Hi TDifEQ ; your oppo is converting the dsd to pcm [24/88.2 is the nearest pcm bit depth/sampling rate to 1 bit dsd that oppo likes ;176khz is used by others like sony].Go into the audio format setup menu and choose hdmi audio; bitstream as well as sacd output; dsd not pcm . This should equate pretty well with the 95 as its from my old oppo 83 manual..To be safe make sure the oppos downmix options are off if playing multichannel btw This should see if there are any dsd anomalies from disc Took ages for Sony to let hdmi send a digital signal hence the rats nests of multichannel analogue cables . The oppo can also send dsd straight to its dacs for conversion to analogue if you want to try the oppo's sabre dacs vs the rmc1's btw

tom9933, did you get a chance to watch any ATMOS content on the Shield via PLEX through the RMC1 yet? I’m curious to see if you are experiencing the same dropout issue as I and others have documented. You would need to watch at least 15-20 minutes to see if anything pops up. This would then at least answer the question of whether or not the network or the RMC1 is the issue. Please let the rest of us know your results when you do.

I checked a few files but didnt watch anything that long and only have the LCR connected at this time. Do you hear it on all channels or does only a specific set drop? The TrueHD content I tested last night was coming up with Atmos. I won't have the full rig going for probably another week, the rack comes in a few days and I have a lot of wiring to do... I'm also debating on waiting for Emotiva ears (out of stock) vs doing 4 post shelves... I'm really hoping Emotiva comes back with an ETA today as I'd rather do ears but I also want to get the system up and running.. BTW re guarding Kodi, tired it in the past hoping to resolve some audio transcoding issues and went back to the native Plex client. Are you directly playing the media off a USB/Network device or are you using Kodi as a Plex client?

tom9933, the dropouts are in all channels and mainly the LCR. It is pretty consistent with all streamed content over the NAS through PLEX/KODI. As to the IR input on the rear I just got mine functioning again. You need an IR extender with a powered input/output plug from BAFX. Make sure the wire you run is stereo (2 rings on the plug) into the back of the RMC1. Set both Front IR and IR Blaster to disabled you and should be good.

Media is being hosted on my NAS server running UNRAID.

I can also say I'm running Kodi through a RP2 and a physical hard drive and have no audio drop out issues.

I can also say I'm running Kodi through a RP2 and a physical hard drive and have no audio drop out issues. May I ask what you mean by RP2? Also, is the physical hard drive inside your RP2 and then out via HDMI to the RMC1 or is the HDD on your network and streamed via cat5e/cat6? Just to clarify, you are streaming ATMOS content through the RP2 and no audio dropouts?

Raspberry Pi 2.
2.5" external HDD > USB Cable > RP2 > HDMI cable > RMC-1
Kodi can only output 7.1 with the Raspberry Pi 2. Though I'm only using 5.1 in my theater, I'm having the RMC-1 use the Neural upmixer.
Here at the office we have tested it the same way with our 9.1.6 theater taking 7.1 and upmixing with the Neural upmixer.

Unfortunately that doesn’t answer the question of streaming native ATMOS content off of the HDD either networked or directly connected. You guys need other streamers at the office to replicate the issues others are experiencing. Given how much money was spent on the R&D with the RMC1 it would be a very small investment to ensure a properly functioning unit.

Here at the office we are steaming through the network with my RP2, the OPPO 203, a Mede8er box, PS4, XBox One, Amazon Cube, Roku Ultra, a Sony Bluray player, AppleTV 4, and the NVidia Shield with our Synology 8 bay NAS movie server. We have been running local vs network content for months while troubleshooting the firmware.

Today, pulled the HDfury device out and everything worked ... got DSD to work. Bought six Dr HDMIs back in 2014 ... too old tech. LOL. Listened to classical music from a SACD sampler disk ... WOW ... extremely clear music ... captivating and intoxicating to listen to. RMC-1 ROCKS!

Another item, or at least variation of an issue to add to my list. While streaming Game Of Thrones using the HBO app on the AppleTV, at 49 minutes I had the buzzing audio issue return. This weekend I had a serious buzz happen in all channels while streaming a UHD movie, the buzzing was continuous until I was able to locate the remote and change the volume. As soon as I changed the volume the buzzing stopped, but took me about ten seconds to find the remote to change the volume. This is the only time I have experienced this buzzing with my RMC-1.
I was streaming the UHD version of Deadpool from Vudu through a Roku Premier. I do not have any details about the incident because I nearly soiled myself when it happened.

We have been running local vs network content for months while troubleshooting the firmware. That’s great. So you guys should be seeing what we are experiencing with ATMOS dropouts when streaming off of a NAS over the network. If not then with which streamers are you having success and what configuration? Just trying to get to the bottom of why this is happening; whether it’s network, processor, or streamer related.

So I did a bit of testing at lunch and I do see occasional blips with both Dolby Digital 2 channel and TrueHD Atmos content. It seems like the blips are around the 15 minute mark but I don't think it's quite that consistent. I also found another very annoying issue if you pause a movie and then restart it, the audio takes about 6-7 seconds to resync. The display changes from PCM 2.0 to Atmos after about 5 and then the audio starts playing a second or two after the display goes away.

Obviously everyone's setup is different and we all seem to be experiencing different levels of success/failure, but I will share that with my setup when I have quick audio dropouts the timing is constant enough you can set a clock by it. For instance, if I get an audio dropout at ~12 minute mark, I know my next audio dropout will be at 24, 36, 48, so on and so forth. Every so often I will miss a time slot, but rarely. I've also found that if I I pause, stop or skip chapters, the timer resets. If my first dropout happens at 12 minutes, I watch until the 20 minute mark, then skip to the next chapter (timestamp 30 minutes) my next audio dropout occurs at 42 minutes of movie time.

deewan, tom9933; this would seem to move the needle towards an issue with the audio clock (or something along that line) and the traffic through the network. Deewan’s comments about resetting the timer is what I need to test on my own system to confirm. Can someone over at Emo reading this test it on your end to see if you can duplicate it? This issue needs to be resolved prior to Firmware 1.4 being released.
