Since the update, my Asus Xonar sound card is not working, there is no sound from the output. But it is not dead, the mic input on the card works.
pacmd list-sources | grep muted
muted: no
muted: no
muted: no
muted: no
muted: no
The outputs are not muted, I checked it. I also tried to erase the pulse config, but had no effect. I can’t run pulseaudio-ctl command:
pulseaudio-ctl full-status
(standard_in) 1: syntax error
(standard_in) 1: syntax error
(standard_in) 1: syntax error
Cannot determine which version of pactl is installed. Aborting.
Meanwhile, I can use my onboard sound card, but sometimes the audio is getting muted and un-muted repeatedly. Or the output device switches back and fort? I do not know.
This whole situation may be related to this bugreport: https://forum.manjaro.org/t/no-sound-after-upgrade/9823/29
In short, pulseaudio should be updated soon, it has some bugs in the current release.
*edit: it is the same with both 5.8 and 5.9 kernel.
