Brief Version: https://askubuntu.com/questions/995281/audio-devices-
disappear
TL;DR: My version of Kubuntu keeps losing audio devices/audio and cannot
recover, including after reinstalling pavucontrol, alsa, etc. I can't
figure out how to get this to stop, and is a certain... and very
persistant bug. I've tried multiple uninstalls, and reinstalls, and
occasionally, one day after restarting the system, the audio bug is
present and never goes away again. All attempts to raise volume don't
work that I've tried. The askubuntu page has more detail, including my
hardware specs.
I should also add that the bluetooth connector also has audio problems
and appears to be broken as well.
+ After recommendation of a person on Kubuntu forums, I have found a
+ temporary fix. Running:
+
+ sudo apt-get remove --purge alsa-base pulseaudio
+ sudo apt-get install alsa-base pulseaudio pulseaudio-module-bluetooth*
+ sudo alsa force-reload
+
+ Seems to work 100% of the time, however, the bug always re-appears.
+ Naturally, this is rather inconvenient, and requires connection to the
+ internet.
+
+ By process of elimination, I have ruled that installing plasma-pa*
+ always causes the bug. Every time plasma-pa* is installed, the bug
+ appears. When it is uninstalled and sudo alsa force-reload is run, sound
+ is always restored. Attempting the reload while plasma-pa* is installed
+ always fails to restore sound.
+
I can provide stats/logfiles/proof upon demand, just tell me what to do.
