My HDMI audio output from AMD RX6600 has disappeared after update and shutdown yesterday night, I've performed the follow checks:

pulseaudio -k

Does not solve the issue

aplay -l

Output: **** List of PLAYBACK Hardware Devices ****
card 0: PCH [HDA Intel PCH], device 0: ALC3220 Analog [ALC3220 Analog]
Subdevices: 1/1
Subdevice #0: subdevice #0

pactl list short sinks

2 alsa_output.pci-0000_00_1b.0.analog-stereo module-alsa-card.c s16le 2ch 44100Hz IDLE

sudo alsa force-reload

Does not work

Does anyone has any idea on how to get around this problem? Thanks so much!

  • Opps sorry, Linux 5.19.0-35-generic, Release 22.04.2 LTS, thanks for the reminder! – ANC Mar 03 '23 at 09:14
  • If you select an older 5.15 kernel at grub during boot; is it still working? (ie. when using the GA kernel.. at last resort that maybe a work around if a solution isn't found with the HWE kernel stack (ie. 5.19 etc)) – guiverc Mar 03 '23 at 09:18

    Oh I totally forgot about this! It works now, so we can narrow down as a driver issue, I'll report it through Ubuntu, Thanks! – ANC Mar 03 '23 at 09:23

    I ran into the same issue. Can you share the link to the bug report? – sdaffa23fdsf Mar 03 '23 at 23:05

Seems like an issue with 5.15.0-35 kernel, the problem went away with 5.15.0-67 kernel
