Title:
No sound after latest update for Ubuntu 12.04 LTS
Status in alsa-driver package in Ubuntu:
Incomplete
Bug description:
After runing the latest update this morning I no loger have sound on
my Dell laptop (Inspiron E1705). My sound control panel used to show
the sound output choices of "Digital Output(S/PDIF)" and "Analog
Output" but after the upddate it just shows "Digital Output(S/PDIF)" .
These Dell laptops requiring modifying the analog-output.conf.common
file, and when I remove that modification "Analog Output" appears as a
choice again sound works, but badly because these Dell's require that
modification or the sound either silient or very loud through the
range of the volume control. I imagine many people with these Dell
laptops are having this problem since this update. The modification
that makes these Dells work (which this update broke) is in the file:
/usr/share/pulseaudio/alsa-mixer/paths/analog-output.conf.common
and replacing:
[Element PCM]
switch = mute
volume = merge
override-map.1 = all
override-map.2 = all-left,all-right
with the following:
[Element Master]
switch = mute
volume = ignore
[Element PCM]
switch = mute
volume = merge
override-map.1 = all
override-map.2 = all-left,all-right
[Element LFE]
switch = mute
volume = ignore
Making that change and restarting removes "Analog Output" as a choice for
Output's. I will be glad to provide more information about my system if
someone will tell me what would be useful.
