Ubuntu 16.04 lost sound

[haquezameer]

Sound is not working and it shows dummy output. Doing pacmd list-cards displays no cards. Any help is appreciated. Thanks.

What exactly do you mean with "dummy output"? Maybe this thread can help? A bit of sudo modprobe snd-hda-intel maybe?

Is pulseaudio running? My sound doesnt automatically start up, so I need to start up pulseaudio in my .bashrc Try: pulseaudio& In the terminal and see if that helps.

it gives me output like this

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

@oliver-dvorski that thread didn't work for me. By dummy ouput I mean the devices that are showed when you open the sound menu.

Tried many solutions mentioned on ubuntu community and stack overflow. Nothing worked for me. I installed ubuntu 17.04 and strangely sound was working. Upgraded to 17.10 from 17.04 using software updates and everything is working good.
Just leaving this here, in case someone faces sound issues. Thank you.
