Description laser.eyess.trackers 2022-12-26 17:18:05 UTC

This is a regression and someone has bisected it to ef6f5494faf6a37c74990689a3bb3cee76d2544c[0]. There is additional discussion on Arch linux's bug tracker[1] and forums[2] about the issue. In particular, multiple confirmed fixes when reverting ef6f5494faf6a37c74990689a3bb3cee76d2544c.

I can confirm that the commit reverted fixes my issue with my Ryzen 5 PRO 6650U CPU and radeon 680M GPU. I'm unsure what debug logs are useful here, but I'm willing to provide them as needed. I could not notice anything different in dmesg/udev between 6.0 and 6.1.

It's worth noting that the PCIe devices don't even show up with that commit applied, it's not that HDMI audio won't output, it's that the devices themselves *do not exist*. So it makes sense that this commit, which touches on enumeration of the devices, seems to have caused this regression.
