Title:
Sound doesn't work randomly. [700Z3A/700Z4A/700Z5A/700Z5B, Realtek
ALC269VC, Speaker, Internal] No sound at all
Status in alsa-driver package in Ubuntu:
Confirmed
Bug description:
Sometimes audio randomly stops working. It's happened 3 times now, and
requires a restart to fix.
It seems like it happens when I put my headphones into the audio jack, but
this could just be correlation, rather than causation, as I put my headphones
in when I'm trying to listen to audio.
Sound doesn't work for both my headphones, and my internal speakers
when this happens, and the right audio device is selected.
