SUMMARY
After the upgrade of the 2020-11-20 and after a reboot the sound device
(soundblaster 2zs) that I used is no longer available.
STEPS TO REPRODUCE

OBSERVED RESULT
Audiocard/device no longer available
EXPECTED RESULT
audiocard/device be available
SOFTWARE/OS VERSIONS

KDE Plasma: 5.20.3
KDE Frameworks: 5.76.0
Qt: 5.15.1
kernel: 5.4.0-55-generic
ADDITIONAL INFORMATION
Don’t know if this is related to the other tickets about pipewire/pulseaudio.
This one is a bit diferent, it’s not that no sound is available, it’s the fact
the audiocard and its profiles (analog/etc) are not even available therefore no
sound.
When booting the usual speaker “pop” sound, like when you turn on a speaker
system, is made.
When in terminal and typing alsa-mixer, the audio device can be seen.
The audiocard can be seen when typing “ cat /proc/asound/cards “ , the
following is given:
0 [NVidia ]: HDA-Intel - HDA NVidia
HDA NVidia at 0xfb080000 irq 68
1 [Audigy2 ]: Audigy2 - SB Audigy 2 ZS [SB0350]
SB Audigy 2 ZS [SB0350] (rev.4, serial:0x20021102) at
0xb000, irq 16
In case it’s a pipewire problem:
Used to work with 0.3.8-1+20.04+focal+build3
Doesn’t work with current version : 0.3.15-0xneon+20.04+focal+build5
Tried and didn’t work:
– sudo systemctl disable --global pipewire
– will not remove pipewire because it wants to remove the plasma-desktop among
other essential packages
– pulseaudio -k
- pavucontrol doesn't list the device
Attached is the result of the upgrade or more to the point the “cat
/var/log/apt/term.log”
