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
