I'm not sure when this happened or why, but
pacmd list-cards shows
0 card(s) available..
Now my audio doens't work, and all I see in the Sounds application is "dummy output".
How can I re-add the sound card? I should note that I wasn't messing with this. One day it just randomly stopped working.
This is what I see from
**** List of PLAYBACK Hardware Devices **** card 0: PCH [HDA Intel PCH], device 0: ALC255 Analog [ALC255 Analog] Subdevices: 0/1 Subdevice #0: subdevice #0
I have tried googling for this and tried various fixes such as
sudo apt-get dist-upgrade and re-installing the audio stuff. Nothing has worked so far.
