Title:
No sound output except for headphone output
Status in alsa-driver package in Ubuntu:
Incomplete
Bug description:
Description:
In 11.10, my audio worked perfectly.
However, in 12.04, on my intel HD audio, I can only get output from the front
panel headphones output. None of the outputs on the back panel work.
There are some unusual symptoms. For example, the "headphone" checkbox
is always checked, and if I uncheck it, it mutes all sound (systray
icon shows muted). Even if I mess with all sliders, muting and
unmuting them, the back outputs won't work.
Attempts to fix, in no order:
-run from liveCD
-purge + reinstall alsa and pulseaudio
-all combinations of settings in alsa-mixer, pavucontrol, sound control panel
-disable + re-enable intel-hda in BIOS
-all suggestions on the soundtroubleshooting and hdaintal sound wiki pages:
