So in another thread I detailed the persistent fault I was finding with Navi 2x/3x GPUs, primarily RX 6700s but also a 6750XT and 7900 GRE. Never did fix it completely on 2x/3x, but when I picked up a 9070 all my audio problems went away, without the performance issues of Arc or resorting to a RX 580.
Right up until Fedora hit 6.15 mainline. Now it’s back to as bad or worse than I was seeing from the Navi cards. It’s a similar sort of issue as prior, where the audio clipping/stuttering is somewhat dependent on CPU load type. Initially I was rolling back to 6.14.9 to avoid it (and that was fully successful), but 6.16rc3 is a loser as is every 6.15.x release. It’s only affecting HDMI audio, but it’s source-irrelevant. Actually, it’s rather easily far worse than Navi had it on the rc kernel.
I’m not sure I want advice or just someone to scream at for not having this on their testing.
I’m not sure what you mean there precisely, but if I swap audio devices to something other than HDMI audio the problem goes away, whether that’s using onboard sound or a USB headset.
Having pavucontrol open seems like it may help, which is interesting. At first I thought it was down to having split something out to onboard audio, but after closing the UI for Volume Control it resumed skipping almost immediately, repeatably. Edit: Actually, only if Volume Control is visible it seems.
You see, I’d be inclined to go “well I guess HDMI is the problem” except for the fact it works properly when they aren’t breaking it. Also was reliably flawless on Polaris for me, but Navi variants were problematic. And then the 9070 was flawless until recently.
I agree 100% with “it works properly when they aren’t breaking it” on the HDMI side. Problem is they keep breaking it and don’t appear to be improving on that front.
I haven’t had those issues with USB class compliant audio.
