Prior to installing 5.4 I had two issues. The first was banding with 4k HDR which is now fixed. The second issue which I have been speaking to Emotiva about is missing audio on the Apple TV 4k The issue as described to Emotiva is as below. I am sure if Emo can duplicate the issue it will be fixed as from my experience their customer support is exceptional. From a personal perspective it would be good to know if anyone else has seen this issue. The Apple TV 4K loses the center channel speech information, not the entire center channel as there is still any ambient sound present on the center channel. I leave my XMC-1 in video standby mode and the problem can exhibit itself from startup or by switching apps from say YouTube to Netflix. This can be fixed by switching to another HDMI input and back again. It seems to occur when the Apple TV audio setting is set to “Best quality available” which converts the audio output from ATV to LPCM. If the ATV is set to output Dolby Digital 5.1 it seems to be more reliable. Unfortunately some apps like “Infuse” pass uncompressed audio formats like DD True HD to the ATV so leaving the ATV set to “Best quality available” is the only option to allow ATV LPCM output and not let it down sample to Dolby Digital 5.1. This did work without issue on the original XMC HDMI board. I have two display devices connected to the XMC-1, a Vizio 1080p TV and an Optoma UHZ65 4K projector, this issue occurs when using ether device. RMC-1 has major PCM issues as well.

The loss of center channel audio is happening all the time in my setup, but it's somewhat different. I am on a 4.1 channel setup (no center channel) so what should should be center audio is being mixed to the 2 front channels. With my Apple TV 4K roughly 50% of the time I go start content playback where it switches from 2.0 to either 5.1 or 7.1, I am seeing in the UI that audio is locked to 2.0. I am only getting the front effects, but am missing surrounds and center content. Switching inputs and then switching back resolves the issue 100% of the time, but having to do this continuously is aggravating.

I have experienced both problems with 5.3 and earlier releases. Since installing 5.4 two days ago, I haven't seen either problem. I'm able easily able to get HDR banding on 5.3, so I'm pretty confident that that problem is fixed. I do not have a reproduction sequence for the loss of the center channel with Apple TV, so I'm less confident that that bug is fixed for me. I'm using my XMC-1 with a JVC projector, and Apple TV and Tivo sources.

I just wanted to update here.
I had the board replaced by Emotiva in July. When I got it back, occasionally when I would turn the unit on, I would not get any video on any input. It required a hard reboot with the switch on the back to correct the issue.
I have not updated the FW at all since then. I am still on v5.2. I have not had to reboot the unit in over two months. I'm not sure why things have changed, but it seems to have self-corrected.
I'll probably be updating the FW soon, though. Next week I will be swapping out my projector for a JVC DLA-RS540U and adding an AppleTV 4K. I want to get that stuff into the system before I do any updates, though, just to see if it will show any of the banding or other issues people have been having. It seems like the new FW has everything pretty solid, but I'll be curious to see how an older FW version works with new hardware in the loop.

Given all the problems folk have had with previous FW and Apple TV (some still on-going) I would upgrade the FW now rather than waste time finding old bugs. But, your time is your own...

I have already been in contact with Tech support re this problem but will follow up again. As an update up to my original post where I said : "It seems to occur when the Apple TV audio setting is set to “Best quality available” which converts the audio output from ATV to LPCM. If the ATV is set to output Dolby Digital 5.1 it seems to be more reliable." I have since observed the problem with the ATV set to Dolby Digital 5.1 as well so it seems there is a general problem with audio switching from ATV which is only fixed by switching inputs. This is very frustrating especially as the original HDMI 1.4 board was solid as a rock for me. Hopefully the V3 board will get there eventually.

So spent some time yesterday with the XMC-1 and Dirac with a new pair of speakers from PSB ! The results are astounding ! Just love the sound , tried many inputs , cables ect... In process made a discovery regarding start up input present First noted that if I present to for example optical 1 ,2 or 3 from audio source ( in this case Sony XBR Z9D) In witch I stream All audio formats. The XMC 1 will always keep switching back to HDMI/ARC and posting back automaticly. So what I'm saying is that if I lie to the unit to start up on another input it will have sound at start up ! But if I lable The HDMI/ARC as start up no sound until I switch inputs manually .
Any thoughts. ?

It's your display telling the XMC to switch over to ARC and not the XMC deciding to do that on its own. Go into the XMC's settings/advanced/HDMI CEC and uncheck the input change option. In the HDMI chain the display is king (primary). All devices must conform to the display's needs. If you remember that, troubleshooting weird problems becomes easier. But remember when you want to use ARC you will need to switch to that input manually.

Not true if you read what I said is that if you want use the ARC channel for audio you have to allow the unit look for it yes, but you must set the look for input to something other than HDMI/ARC . The unit automatically will switch back to HDMI/ARC. At this point the unit will start up without having to toggle the input for sound. I do believe it is a firmware issue.

I must not be understanding what you are trying to do. You are using both optical and have ARC enabled for the Sony's built in sound?

I see your confusion This is the order of operations The XMC is connected to TWO THINGS in this order 1 .The Sony input 3 ARC/HDMI to XMC-1 output ARC/HDMI Purpose to play Audio for Tidal , Spotify, Netflix's ect.. .on the return channel 2. The Oppo's output to XMC-1 input 1 and 2 Purpose to play Audio and video through Simple it always worked i purchased this unit March 2017. It stopped locking ARC with the new board . I do believe it's a known issue.

Done that , spent an entire day trying different things this is when I discovered the resolve by lying to the input at start up and go through one cycle and after that it starts up with ARC and all CEC checked. And if everything is off all I need to do is insert a disk into the Oppo and it turns on the XMC-1 and the Sony. Allowing full control of everything with the Sony remote ! Everything One remote !

EDIT: Turns out Emotiva installed FW 5.3, not the current 5.4 so hopefully that explains a lot of these issues. Ill post an update once I have 5.4 running.Well, I finally sent my XMC1 into Emotiva for the V3 board upgrade after holding out until now in hopes that all the kinks would be ironed out. I just got it back and hooked up and sadly its looking like its not there yet. Im experiencing A/V dropouts on multiple inputs (Tivo Bolt, Panasonic 820k Blu-Ray). I literally had a dropout the very first time I turned it on, and only got signal after switching inputs back and forth. On top of that I'm seeing pretty bad image degradation on all inputs. I had been running my inputs direct to my tv (LG B8 OLED) for a couple months leading up to this so I know exactly what the image should look like, and having the XMC in the signal chain is definitely changing things. For one thing there appears to be some artificial sharpening going on. Im seeing a lot of grain/noise, particularly in brighter scenes, that was not there before. Im seeing some motion "jaggies" that I did not have before, and lastly, Im seeing what must be the "banding" issue in some bright scenes (I thought this issue was fixed?). On top of all that the menu navigation seems noticeably slower. Im getting a 1.5-2 second delay with each button press when navigating the menus which is pretty brutal. I have to say Im pretty disappointed. My XMC was highly stable before the update and I made it clear to Emo that I didn't want to trade that stability for 4k and HDR, but they assured me that it was ready for primetime. Im also a disappointed that Emo tech support let my unit ship out in the state it's in. Lastly i'm disappointed that they decided to release the RMC before this project was really finished, as Im sure a lot of their time and resources are going to go towards that project. Unless things really change I would not recommend this "upgrade" to a friend. All things considered, with all the artifacts, the video with 4k and HDR through this unit is no better than it was it was with 1080 and SDR before the update and on top of that the functionality is compromised. HDR is great in all but not great enough to make this acceptable! Im going to spend some time on this over the next couple days, hopefully I can fix some of these problems. To those of you who say the v3 upgrade is ready for primetime, what am I missing here?

nickwin, you didn’t mention what firmware you’re on, since 5.4 is relatively new maybe your time at the factory predated it.

nickwin, you didn’t mention what firmware you’re on, since 5.4 is relatively new maybe your time at the factory predated it.a I just got it back this week so I assumed it was the most recent FW, but ill double check. That would explain a lot if that's the case. EDIT: It's 5.3! Ill update it today, hopefully this solves some of my problems. I guess I should have checked this before, but I just assumed they would have flashed the most recent FW. Good suggestion!

nickwin - Are you using Active HDMI cables? If found the 4K board in the XMC-1 doesn't like them and the dropping of HDMI sync is a common symptom. I switched to passive cables (Certified) and the problems went away. I still get the occasional HDMI failure, but switching the input usually brings it back. When I say occasional, it happens maybe once a month.

bitzerjdb is spot on. Once I replace my "certified" HDMI cables with another brand, my DirecTV HLG HDR started working. Same experience on my Roku 4k streamer.
