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.
pulseaudio --startthe problem is temporarily removed, after reboot it appears again. – ubuntuuser Apr 06 '20 at 10:25
