Hello, i encounterd a possible alsa bug with the "ID 0d8c:0006 C-Media
Electronics, Inc. Storm HP-USB500 5.1 Headset".

After Ubuntu 10.04 LTS (Ubuntu 10.10 works, Ubuntu 11.04 doesn't work at
all, Ubuntu 11.10 and newer have the bug), the headset only plays sound
at maximum volume level if the volume is turned down just a little no
sound is being played.

I have filled a Ubuntu bug for 12.04 LTS at:
https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1200925 .
I was advised to contact this mailing list.
