Title:
No sound after 20.04 update with timidity installed
Status in timidity package in Ubuntu:
New
Bug description:
After update from 18.04 to 20.04 sound stopped working.
KDE does not display Xonar sound card at all.
$ aplay /usr/share/sounds/alsa/Front_Center.wav
does not make any sound
Alsamixer displays Xonar set at full volume but changing anything
there does not seem to have any effect.
Moving/deleting the pulse config ( ~/.config/pulse/ ) and restarting
machine did not have any effect.
Running:
$ sudo alsa force-reload
fixes the issue (until restart sound is back, and is displayed properly in
KDE)
(data arecord and cards display same data before and after restart)
$ arecord -l
