After using an external microphone and now having unplugged it my sound does not work any more. The command

aplay /usr/share/sounds/alsa/Front_Center.wav

gives "unable to connect".

Typing

aplay /usr/share/sounds/alsa/Front_Center.wav

plays sound, but says

Home directory not accessible: Keine Berechtigung
Home directory not accessible: Keine Berechtigung
Wiedergabe: WAVE '/usr/share/sounds/alsa/Front_Center.wav' : Signed 16 bit Little Endian, Rate: 48000 Hz, mono

And

sudo addgroup <myusername> audio

gives that the user is already member of the group.

  • With `pulseaudio --start` the problem is temporarily removed, after reboot it appears again. – ubuntuuser Apr 06 '20 at 10:25
