Dear experts,
I am trying to find out why I cannot hear any sound when I plug in headphones in my laptop. Data points:
- latest updates
- speakers work just fine when I unplug headphones
- alsamixer looks good
- pavucontrol looks good (bars move when audio is supposed to be played)
- tried clearing ~/.config/pulse and restarting pulseaudio, no luck
- using an USB sound card also works
- issue started last week, was not the case before. I did not do anything obvious to the system in that time frame
Sink looks OK to me (but I am not an expert):
> pacmd list-sinks
1 sink(s) available.
