Fedora multi channel sound issues with Fedora 33

Hi

Just upgraded to Fedora 33 from 32 and I am having sound issues. No issues under 32.

I have a intel NUC attached to a Denon amp via HDMI, Outputting 7.1 audio.

If I pause any sound like a movie, it stops working, no sound. If I open setting and toggle the Configuration to any setting and back the sounds starts to work again.

Any ideas on how to fix?

Very similar issue for me here as well. Using an Intel CPU/graphics with HDMI audio/video output. I upgraded from FD32 to FD33 and I’m also having the same problem. If I pause audio or video, it will frequently fail to continue playing the audio stream when I resume playing an audio or video source. The video continues to play, but the audio will not pass back through HDMI.

I have to either unplug/re-plug the HDMI cable, or switch audio sources from local speakers back to HDMI, this will usually cause HDMI audio to work again until another pause in the audio.

Sounds like the exact same issue I am having. Intel cpu and graphics as well.

I would normally report this type of thing in bugzilla but this is a really hard thing to report as I’m not sure what component is causing it. Cant see anything in the logs when it happens. Also tried going back to a 5.8 kernel and same issue.

It might be Gnome specific, on Intel laptop, with upgraded F33 KDE, HDMI sound works without issues. At least for videos in Firefox.

Hi,
I have the exact same issue: a fresh install of Fedora 33 on a brand new Intel nuc NUC8i3BEH plugged on a AOC monitor with a HDMI cable.

Just tried Fedora 32 on same setup and the issue is not present on 32. So looks to be 33 that is causing it.

I have raised some bugs for sound issues I am having on Fedora 33:

I have done some more testing and:

On Kernel 5.8 no issues/problems. On kernel 5.9 or 5.10 the issue is present.

This seem to be kernel issue on any version > 5.8.

On my NUC7CJYH under Fedora 32 and now 33 (KDE), since kernel 5.9:
a) alsactl and Xorg processes connected to sddm (?) remain hanging
in “D” state after an interval between 1 hour and 2 days. That causes
the console (sddm and tty2 etc) to be invisible / unusable
b) reboot / shutdown remains hanging - have to switch off via PWR button
