Thank you Morgan for fielding this; and Guillaume for the journal.

Since this problem is tied to a new kernel (5.10.60), and the previous one (5.10.56) works OK, assigning this to kernel/drivers.

Comment 4 Thomas Backlund 2021-08-29 21:11:48 CEST

Please try with  kernel-5.10.61-1.mga8 from Core Updates Testing

Comment 5 Guillaume Royer 2021-08-30 20:31:19 CEST

I updated today kernel-5.10.61-1.mga8.

Sound is back on my computer:

- HP out -> OK
- Jack out -> Ok

No regression with HDMI out but switching between two device not automatic anymore.

If I plug HDMI cable, I have to tune it in pulse audio.
When I unplug cable the sound doesn't come back on HP or jack.
I have to reboot.

Comment 6 Alan Richter 2021-08-30 20:59:18 CEST

I had the same issue, to keep the sound from muting on changing an HDMI channel or the system shutting down video, I had to pound this out in /etc/pulse/default.pa:

load-module module-switch-on-port-available

A fix without rebooting is to bring up pavucontrol (Pulse Audio Control) and unmute the device in the "Output Devices" tab.

HI ran into the same issue with sound on kernel 5.10.60-2 on Dell Chromebook:

CPU:   Celeron(R) CPU  N2840  @ 2.16GHz
Audio driver:
Description: ‎Atom Processor Z36xxx/Z37xxx Series High Definition Audio Controller

upgrading to test 5.10.61-1 fixed the audio problem

As a substantial percentage of active bugreporters found this, i think it would be good to get this out ASAP as it probably affects many users.

@tmb: should we test this version for release, or you want to bake yet a new one first?

Comment 9 Morgan Leijström 2021-09-03 13:10:45 CEST

Ah, i see a .62 compiled three hours ago already, great :)

I saw in my /etc/pulse/default.pa that load-module module-switch-on-port-available was already written.

Switching problem is still here.
