Title:
[USB-Audio - USB Headphone Set] Switching between outputs sets volume
to 0 in alsa mixer, causing users to think it's broken
Status in alsa-driver package in Ubuntu:
Incomplete
Bug description:
michael@michael-dell-01:~$ lsb_release -rd
Description: Ubuntu 10.04.1 LTS
Release: 10.04
When changing output settings in System -> Sound, the volume in the
alsa mixer were set 0%. It took a few hours before I realized the
volume controls were seperate and I would need to raise the volume to
100% by using alsamixer -c 1.
It may be better to amend the routine which initiazes the volume to
set it to 25% if it does not have a last-setting saved.
