Status in alsa-driver package in Ubuntu:
Expired
Bug description:
Since the update to 3.2.0-51-generic I have a very annoying problem
with audio playback:
1.) Volume jumps up and down randomly (even when all levels are 100% in
alsamixer)
2.) Even when external speakers are plugged in the audio jack, the NB
speakers are active
