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

Beware of 3080. I had a Seasonic 1000W PSU working perfectly for 3 years. A 3080ti killed it, as it has insane momentary current draw. It is a known problem of the 3080. Seasonic RMA the PSU and sent a newer model with the fix of the problem.
SamuriHL:
The 3080 has been running fine in that machine for a while. But the machine won't post at all so either I damaged the PSU or something else. I'll know Monday if it's the PSU. I switched my order from the Corsair to a new eVGA. I've had good luck with the eVGA over the years. But I want one with the new nVidia connector as I'm not jazzed about putting an adapter with 3 power cables attached to it in my machine. If when I get the new PSU it still doesn't boot, then I'll have to decide what I'm going to do about just building a whole new machine. With AMD Zen 5 releasing this year, I may just say screw it and not have an HTPC for a few months. Worse case I can always grab my long zeskit HDMI cable and run it to this laptop which has a 4080 in it when I want to use HTPC functionality for a few months. I'm just not wanting to spend the money right now for a full rebuild (cpu, mobo, and memory)
EDIT:
I threw the 3080 back in the machine I bought it in. Only way I could acquire a 3xxx card during the pandemic was to buy a whole machine. It's an ASUS machine with some intel i7-11700kf CPU but it at least boots. There's ZERO chance of fitting that 4080 in that case though. Might be a temporary solution if I can't get my HTPC working.
JimH:
I moved this since it's now a purely hardware discussion. If you want the first part split and moved back, let me know where to split it.
SamuriHL:
I personally think people need to know about this issue with the 3xxx cards. If Manni and I weren't sure that it was NOT a JRiver issue, I can promise you that others might come to the conclusion that it's a JRiver problem. And that would be a shame given that nVidia quality control is at fault.
SamuriHL:
New power supply did not fix the issue, as expected. Something else has died. The manual states that q-code 00 isn't used. Um, what? That's ALL it displays. So it's not even trying to post. My guess is the mobo is dead. At this point I'll see what happens in July with the AM5 Zen 5 CPU's and motherboards. I'll just build a new machine and use the 3080 machine until I can make that happen. I tried re-seating the CPU and that made no difference so it really does seem like the mobo has died. Which is frustrating given that it was not a cheap mobo when I got it a few years ago.
