Problem: I can't play any sounds.
In Settings -> Sound -> Output there is no device listed.
System: Ubuntu 18.04. This is my laptop, only one user ever connected
Attempts
I've tried lots of forums, threads, ideas, nothing worked.
(1) I've tried
$ aplay -l
returns the devices correctly
(2) I've uninstalled pulseaudio and reinstalled with no success.
(3) To check the groups
$ sudo groups <myuser>
which returns
sudo audio pulse chrome-remote-desktop
(4) If I try to kill it using
$ pulseaudio -k
I get
E: [pulseaudio] main.c: Failed to kill daemon. No such process
(5) IF I try to start pulseaudio
$ pulseaudio --start
then I get
E: [pulseaudio] main.c: Daemon startup failed.
What am I missing? How can I grant the user the access to audio device?
