Title:
AlsaMixer missing master channel no sound
Status in alsa-driver package in Ubuntu:
Expired
Bug description:
Yesterday (9/09/2014) I updated Ubuntu base via Software Updater and
now my sound does not work out of built in laptop speakers or the
headphone jack.
The Sound Settings (unity-control-center sound) does not show any
devices. AlsaMixer, after F5 (show all) has 2 channels I can change
PCM and Digital, I swear there used to also be a master channel (and
maybe others) before.
