Title:
[SATELLITE L750, Conexant CX20585, Internal Speaker] - Sound from
internal speakers fails after a while.
Status in “alsa-driver” package in Ubuntu:
New
Bug description:
The sound works ok and after a while fails/disapears. Can not identify
what I did, however it was ok month or two ago.
I occassionally update recommended updates. My system uses new
backported kernel that is not original to Ubuntu 12.04, however with
the original updated kernel (the one that is supposed to be current
for my Ubutmu version) it also does not work.
Surprisingly the internal speakers are the only that suffers with this
problem. The HDMI sound works perfect and also headphone jack works
well too.
I have checked mixer controls with alsamixer and no, I do not have
muted outputs. The only weir think I observer is that by default there
is enabled controll that has name Auto-Mute mode. Even when I
manualy disable this controll when the speakers playing ok, the bug
appears too after a while.
I gues that this bug is most likelly related to this one:
