The AVRKey had both the video and audio slides set to the top position. HDMI cables are HDFury cables and one 25 foot Blue Jeans Series-1 cable to my JVC RS500 projector.
CCU > AVRKey; video -> JVC RS500, audio -> Denon x4200w
I used my iPhone Netflix App to cast Jessica Jones at 4K60 4:2:2 BT.2020 12-bit HDR with DD+. I can confirm that short audio drops occur every 15 minutes or so. No video dropouts occurred. With the previous firmware the audio dropouts occurred more often.
From iPhone YouTube App, cast various 4K60 videos at 4K60 4:2:2 Rec709 12-bit SDR with stereo audio. I did not encounter any audio drops during two hours of playback. With the previous firmware, there were a few occasional dropouts.
Oppo > AVRKey; video -> JVC RS500, audio -> Denon x4200w
With Oppo configured for 4:2:2 color space and 12-bit depth, I played the 4K60 Billy Lynn's Long Halftime Walk UHD disc at 4K60 4:2:2 BT.2020 12-bit HDR with Atmos/TrueHD audio. I encountered an audio dropout every 15-20 minutes. No video dropouts occurred. With the previous firmware, the dropouts occurred more often.
With Oppo configured for 4:2:0 color space and 12-bit depth, the Oppo output 4K60 4:2:0 BT.2020 12-bit HDR when playing the same disc. I did not encounter any audio dropouts.
Thank you for the perfect detailed feedback as always, this is conform to our findings here as well. Work underway.

like I said many, many times. And has nothing todo with audio like i've said a trillion times now
Question 2 - Audio output cable
I think what you are trying to say is that quality is NOT as important for audio
, you just wrote it wrong, yes?
Question 3 - AVR LPCM 7.1
I also play a lot of PC games. I always use LPCM 7.1, 24 bit, 96000 Hz (or 48000 Hz).
So yeah I'am 100% sure my AVR can decode this format.
On my PC I have a ROG STRIX-GTX1080-A8G-GAMING
with two HDMI cables that's going out to TV and AVR. Audio is always LPCM 7.1, 24 bit, 96000 Hz (or 48000 Hz).
So it's the same principle there, the AVR never gets any video.
As for the fridge and power outlet. No No No, it's non of that because I know it works. I refer to Answer 3
I feel that you misunderstand what I write sometimes. English is not my first language and its not yours. So I'll try to write in a more standard way. That's easier for Google Translate? There's nothing wrong with asking me if you don't understand what I write, I ask you all the time
I say to myself. Why does he keep asking or talking about the same stuff over and over. And this must be the reason. You misunderstand?
So I ask this one's more, as simple as I possible can.
Why are we talking about Video when it's a Audio problem?
IF I had a bad cable from the PS4PRO
THEN, we could talk about Video because that cable handles both. But as I stated over and over. I use the included PS4PRO
4k60 witch is a 600 MHz. So that chain is 100% rock solid
Question 1 : At 600MHz EMI and integrity are extremely important, a short cable at AVR-Key video output CAN produce issue on the audio via EMI. Especially if they are easy/lose to insert, did you compare that with sony PS4PRO supplied cable ?
Question 2: Yes audio cable quality is NOT so important, sorry my mistake.
Question 3: Ok if you have played same audio format on same AVR without dropout, then your 773 is not yet affected by this dropouts issue affecting Yamaha 763/773
Now to answer your latest question and to help you understand why a cable issue at video output can affect sound sent via another cable, please consider the below to put things in perspective:
Usually most of us here have DSL Internet connection in rural area, or Cable connection at 30-50 or 100, 200MB/S and a few of us in cities should have fiber optic connection at 1Gb/s, the kind of connection that let you download multi Go files in a couple of seconds. right ?
Now imagine you take 18x a fiber optic 1Gb/s connection at it's full speed, you could then download hundreds of Go in a few seconds if all fiber connection are at 100% utilization right ?
Once you can picture this situation of 18x 1Gb/s internet connection running at 100% utilization, then realize that THIS IS EXACTLY what is traveling your HDMI cable at 600MHz ! And now normally you should start to understand why lose hdmi connector cannot work, why short distance is too short for such amount of data and bw (EMI) and why long distance will have integrity issue (or packet loss for internet).
For example if at 600MHz you wind your cable > it will fail.
With this being said, i reiterate that my purpose here is not to put the blame on cables, we have a new device and cables going to you, so we will wait your results on it and we have firmware work underway.
The reason i'm telling you that is because from our experience and history you can read on Integral thread, 99% of the issues at 600MHz, are always cable issue. So until we have more results from you using our cables, we have to warm you about this as most of our customers are getting trouble free experience on 600MHz once they have good cables. Yet once again, this is general, in your particular case we will know soon once you have new units and cables from us and in all cases, we have firmware incoming to fix dropouts issues so one way or the others, your issues will fly away soon.
