Dropouts when bitstreaming Atmos through an HDMI 2.1 AVR with nVidia 3xxx GPUs

What's made it harder is that a few software factors have changed over that period of time:
1) Hendrik did an update in LAV that really helped and the first "kind" of Atmos dropouts" (not long freezes, just Atmos sound drop outs) disappeared.
2) Then MS broke something in an update, which caused long freezes, and it looked like it was fixed at some point.
3) Suddenly the long freezes popped back up here, but this could be because I've given access to the network to the rest of the family, so that's what I'm going to rule out first.
That's why I keep asking details both on the hardware side and on the software side.
As soon as you've been able to test one config, please post all the details for it. Also test at least 4-5 films because it can take that long for the issue to pop up. That's why I kept testing after the first few encouraging results with the 4080, and why I tested FULL FILMS, each of them as long as possible. This issue can take a long time before it happens during playback, so testing 30-60min means nothing. I also think that if the Atmos track is anemic (as with older films), the issue is less likely to appear. It's more likely to appear in John Wick than in an old mono or stero movie that happens to have been remixed in Atmos.

Ah, man, I HAVE to watch John Wick...AGAIN? My heart is broken. LMAO :D Yea, I can't test 4 to 5 movies today but for me this issue was happening quite consistently in almost every movie which is why it was driving me nuts. If it was rarely happening I wouldn't care as much. The thing that's frustrating about this is that with my Ugoos, it NEVER happens. And that's going through the exact same chain as my HTPC...i.e. directly connected to the VRROM, audio to my AVR through the VRROM HDMI audio out port, video directly to the G2 with audio muted. So for me it doesn't seem like a network/nas issue given that the Ugoos is doing the exact same playback as my HTPC. In any case I'll see what happens tonight. The machine I'll be testing on is a prebuilt ASUS Intel 11700 machine. I dropped my corsair 32 gigs of DDR4 3200 in there from my HTPC since it'll never be used again in that machine. It's got a western digital 512 gig nvme SSD for boot drive and I dropped a 1tb SATA SSD as a second drive in the thing. I'll be playing off the 1tb SATA SSD tonight when I test. And obviously my ASUS 3080 TUF card.

Sounds good... Yeah I watch John Wick 3 ten times doing these tests, I had to pick other films after that, all I'm saying is that I've played very long OLD films thinking I was testing because they were Atmos tracks, and I don't think it's testing anything if the Atmos track doesn't need a significant bandwidth. At least with John Wick 3 we know that the Atmos track is lively :)
I never used to have ANY dropout with the Oppo 203 or the Dune Pro Vision 4K Solo either playing Atmos 4K bluray, or the ATV 4K 2021 / FireTV Stick 4K Max when streaming Atmos titles, but I did get ONE Atmos dropout when playing the Oppo 203 recently, so that's one of the reasons why I'm wondering if these new dropouts might be network related. At least it's something I want to rule out here before doing anything else.
I am also getting these drop outs all the time, at least one per title on the HTPC, which is why I'm trying to resolve this. I would still want to fix this if it was once in a while, because one drop out is enough to ruin a film if you're watching it for the first time. I'm only using the Oppo or the Dune to watch a film for the first time (if I care about it) because of these Atmos dropouts. All the tests I'm doing are with films I've already watched or with new films I don't care about (I've watched a LOT of crappy films recently on the HTPC to test this).

I don't tend to buy movies I don't care about. I've got a good 600+ UHD's in my collection now with more on the way this week. I have Ghost Busters Frozen Empire coming today which is probably another good candidate tbh. The Ugoos as we've discussed, I tend to use strictly for Dolby Vision titles although when I want to watch an HDR movie without audio issues I sometimes use it for that, as well. Would love to finally solve this HTPC issue once and for all.

Yeah, believe it or not, I have to watch films (and series) for work, and a lot of them I don't care about. I don't buy them all though, I often rent them (for as long as that's possible, I'm sure at some point they'll stop renting physical discs) if they are not sent to me.
