Title:
[HP Pavilion dv6z Notebook PC, IDT 92HD81B1X5, Black Headphone Out,
Front] volume slider problem
Status in alsa-driver package in Ubuntu:
Incomplete
Bug description:
Volume seems to work fine on the built-in laptop speakers (4 of them).
When headphones are plugged in (two stereo headphone outputs), volume
cuts to zero once the 16% level is reached in Master channel (as seen
in alsamixer).
I suspect that the headphones are not properly detected/setup, because
I have no "analog headphones" profile to choose in pavu/sound
settings, as I heard some other people have. This seems to be similar
to the issue described at
http://ubuntuforums.org/showthread.php?t=1850159 (different hardware,
but a similar two headphone plugs hardware), and partially with the
issue described in
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/429844
The solutions presented (ignore_dB=1, channel=PCM etc.,) didn't work.
