DaFalcon, Found this quickly for E6P ARC under a netflix post. wanna try it? "I changed the audio options for ARC/Optical and i enable SIMPLINK and i changed PCM for Automatic. Thanks" Thanks. I'd already verified those were the settings I was using. I'm not going to turn on the SIMPLINK CEC though as I don't think it's relevant.

One other thing I noticed was that the system doesn't stay muted when I switch hdmi inputs. I also noticed at least once where the on screen display said "mute on" but there was sound playing.

Mmmm, shouldn't this stuff just work? Yes it should..

One other fun fact about the X800 and the MC-700, is when the main menu is displayed upon startup it doesn't pass through the input 1. I've read that the X800 is sending 4k at 60Hz at that point. I don't know if it's 4:4:4 though. If I blindly hit play with a 4k movie in the player, then I will see the movie which is 4k at 24Hz. I've had to run the video signal directly to the TV, bypassing the MC-700 in order to see the main menu. I even tried forcing the player to 4:2:2, but that didn't help.
I would love to get an official list of supported 4k frame rates, bit depths, and chroma values that are supposed to work with the MC-700.

If you move the BenQ to Output 1 and the Sony to Output 2 does it happen to the Sony? Move the BenQ to Outputs 4-6 since I'm assuming it's 1080 and not 4k. Switched Sony Tv to Output 2 and Benq beamer to output 1. So far no "no audio" on either beamer or tv. However, did not test for an extended period yet. Will post what I find. However, this is not a final solution since the TV is supposed to play the 4k stuff and have ARC. Update: longer tests still did not result in any issues with the Sony in Output 2 and the BenQ in Output 1. Both seem to work fine. No "no audio" encountered so far. This is however not the ideal setup for 4K and ARC. With regard to ARC and the Sony TV: I found that when CEC is on ARC seems to work, although the Sony reports problems. Easily worked around by setting the tv volume to 0 and ignoring the on-screen messages. However, the Sony needs to be on Output 1 because of the ARC, resulting in the need for swapping HDMI cables when I want to use it. What can I do to assist in digging deeper into the ("no audio") issues when BenQ is connected to Output 2? Isn't it remarkable that it only seems to happen on the BenQ and not on the Sony?

Marijn, I've seen there's an option for stream only video to HDMI outputs. Maybe you could give this a try for your BenQ output and see how it goes.

I have not been able to find this option however. To demonstrate the issue I have created two video recordings while it happens: youtu.be/a9y89yTV9HMThis shows the BenQ displaying content from the Apple TV, then losing the connection and recovering after a few seconds. What keeps intriguing me is that the Apple TV pauses. youtu.be/-D4usENAQjIThis shows the Emotiva during a similar event a few minutes later. You see the "no audio", then back to normal. Hope this helps describe what's going on and maybe find out?

I'm not at home, I'll take a look at the menu later, and I'll tell you where it's at. Another idea, as it only happens on the BenQ, can you try changing the Apple TV's refresh rate? (instead of 60Hz) and one more thing even if it's only 1080p, are you using HDMI2.0 certified HDMI cables?

Found another bug. It appears the MC-700 handshakes at 480p if nothing else is talking yet. So this constantly puts my Tivo HD into 480p mode, regardless of what mode I set it to internally. It will do this when turning on and off before the TV can do it's handshakes. So if I turn the TV off before the MC-700, the Tivo will be told from the MC-700 that it is now a 480p device because that is the default resolution of the internal OSD. The handshaking on this device is very strange compared to the UMC-200 which has none of these issues.

What keeps intriguing me is that the Apple TV pauses. If they AppleTV is pausing, it is an HDMI dropout. The AppleTV is programmed to automatically pause when the device its HDMI is connected to is turned off, changed input, or disconnected. Something is interrupting the HDMI connection between the two devices, whether it's the cable or the Emotiva itself. It could also be caused by another device connected to the Emotiva via HDMI going to sleep or waking up.

Question remains though, why this happens only on HDMI Output 2 and (so far) never on HDMI Output 1. I can imagine a different chip, but I am hoping this info will help analyze and fix whatever is going wrong.

I've also noticed a total video dropout on HDMI Input 5 with my DirecTV HR44 DVR when I switch from a channel with Dolby Digital 5.1 audio to one that has PCM Stereo. Further channel changes don't recover the video (DVR is always sending 1080i). The only way to recover the video is to switch the HDMI input to another input and back to the DVR input. Once the video is back it will work OK, and switching to another channel with Dolby Digital works after getting the PCM Stereo working. Just not the other way around.
Channel 1 with DD 5.1 -> Channel 2 with PCM Stereo = audio works but video is a black screen Channel 2 PCM Stereo -> Channel 1 with DD 5.1 = audio and video work properly
This is with the 2.9.0 firmware and the heatsink installed.
Anyone else noticed this?

I have missed something. What is the heatsink for, and where do I learn about this? Is there a component that begins failing under temp variations? Does Emotiva provide this? Thx.

Some of the first batch of MC-700's we shipped out would experience occasional audio dropouts when they got thoroughly warmed up. We traced this to a DSP chip that was getting a little too warm under some conditions..... We added a little stick-on heat sink to that chip on all future batches.... which totally prevents the problem..... Anyone who has an MC-700 with that problem can either send the unit in to be updated, or we can just send you a heat sink to stick on yourself. (It's a little piece of aluminum about 1/2" square with peel-off sticky tape on one side.) NOTE THAT THIS ONLY HAPPENED ON THE FIRST ONE OR TWO BATCHES OF UNITS SHIPPED - so, if your unit was purchased after about the first few weeks, it already has the heat sink. (Also note that it only affects some units, and some seem to run just fine without the heat sink.) I have missed something. What is the heatsink for, and where do I learn about this?

Been having lock up issues on my UMC-1 with only some sources, which also seems to only be after some time after powered on. Makes me think it might be temp related. Temperature is often the culprit when there isn't adequate margin in timing analysis for digital designs. Just thinking of possibilities, and seeing how things shake out with these issues before ordering an MC-700.

Since yesterday I started experiencing the sound dropouts which sound similiar to the one explained above: - Everything worked flawlessly for a couple of weeks before - With Dolby Digital 5.1 (either via ARC or any other Input), the sound drops out after a couple of minutes (sometimes it just mutes, sometimes there's some white noise and sometimes a very annoying high pitch) - When I shortly reset the input (for example pausing netflix coming from ARC, which puts the MC700 to NoAudio) it works again for another couple of minutes - While I was in the menu of the MC 700, it froze up on me and I couldn't even shut it off anymore (until a hard reset) - I am on firmware 2.9.
Can this behavior be explained by the overheating issue?

Which chip has to be cooled? And could I just use some standard heat sink (i.e. the one for Raspberry Pi)?

I did a little experimentation today, setting aside my Harmony One and using just the Emotiva remote. I find that if I select the optical input with the remote, then select an HDMI input, and then hit DIG again, I do not reliably return to the optical input. Frequently I get coax, occasionally bluetooth, and very rarely get optical. Is this something that can be fixed in firmware? This is similar to my issue and probably why I can't get the Harmony to work right. Toggle buttons are a pain. That is why I was hoping to disable the input to not let it toggle to Coax. I unfortunately do not have Coax and optical outs to do as previously suggested by jolaca

I have an early MC700 which replaced my Outlaw 975 when I bought my OLED TV. Very frustrated trying to get it to work with my Harmony 650 remote. I can't get it to switch from say "watch tv" (my comcast box) to "watch a movie" (my Samsung DVD) or switch to my Roku Premiere to stream content. I'm going to try inserting delays into the mode changes and see if that helps. Any suggestions??? Finally, I've installed one firmware update, but are there more??? If so what's the latest? BTW, I received and installed the heat sink. It helped. Thanks!!
