Public bug reported:
Description: Ubuntu 18.04.4 LTS
Release: 18.04
No sound playing on internal speakers, headphones (bluetooth which now no
longer connect, or when plugged in through a wire) or wired earphones.
Internal microphone also not working. Issue seems to have arisen following
latest software update within Ubuntu 18.04. These all work fine on the Windows
partition I also have on the Dell Inspiron 5379 machine.
Attempts tried that had no effect:
1. Muting and un-muting speakers through settings (internal speakers are
recognised but not playing).
2. Muting and un-muting, changing sound levels and sound card in alsamixer.
4. Running sudo alsa force-reload
5. Updating Ubuntu software and rebooting.
6. Checking input and output devices on pavucontrol (can see built-in audio
analogue stereo sound slider is responding to e.g. youtube videos, but no sound
actually produced.
7. Running rm -r ~/.config/pulse; pulseaudio -k, then rebooting.
