Ubuntu recommended me to update itself, did it without errors and now... I don't have sound.
- Surprisingly, Spotify still works - it plays the music, but I can control the volume only from within Spotify itself.
- Chrome and Firefox are mute (e.g. when playing videos).
- Volume media keys on keyboard don't work.
- There are no output devices in sound options.
- alsamixer shows 4 empty bars (4x S/PDIF at 00).
I've tried already:
sudo alsa force-reload
sudo apt-get install --reinstall alsa-base pulseaudio
and thensudo alsa force-reload
mv ~/.config/pulse ~/.config/old_pulse
alsactl restore
sudo apt-get remove timidity
--> Package 'timidity' is not installed, so not removed- "Edit the file found at /usr/share/pulseaudio/alsa-mixer/paths/analog-output-lineout.conf and change any instances of Element (such as [Element Desktop Speaker]) from switch = off to switch = on."
- Adding some stuff to
/etc/modprobe.d/blacklist.conf
and/etc/modprobe.d/alsa-base.conf
- "go to BIOS -> disable Internal Speakers -> apply changes -> Enable again -> Apply changes -> Exit."
Basically everything reasonable from google. All to no avail. How can I fix it?
