I installed ubuntu 17.10 on a new laptop today. The sound is not working at all. Tried restarting and a few commands but doesn't seem to help. Was working fine on live cd mode(usb)

tried:

pulseaudio 
E: [pulseaudio] pid.c: Daemon already running.
E: [pulseaudio] main.c: pa_pid_file_create() failed.

not sure if this helps to debug:

aplay -l outputs

  • Is maybe your output muted? Try installing pavucontrol and try changing settings there (such as muting/unmuting). – Tomáš Pospíšek Dec 01 '17 at 20:24
  • @TomášPospíšek it's not; that was the first thing I checked – user1121883 Dec 01 '17 at 20:46
  • In principle you should be able to boot from the live cd, save the alsa settings like this: https://askubuntu.com/questions/50067/howto-save-alsamixer-settings (sudo alsactl store) and then copy the saved settings to your installed Ubuntu and load them there. If it's only some weird setting, then that should restore sound on the installed Ubuntu. – Tomáš Pospíšek Dec 01 '17 at 20:49
  • @TomášPospíšek will try it – user1121883 Dec 01 '17 at 20:50
