My Logitech ClearChat Comfort USB headset is working, but I am having problems with the volume control.

The two channels are unable to lock. The left channel seems to be the biggest issue. In Volume Control the left channel will not turn up. When I move it up, it snaps back to 0. Clicking the lock button causes the right channel volume lower and it stays unlocked. Turning the volume to 0 just lowers the sound but does not mute it. The mute button does work fine.

Alsamixer allows me to move the left channel up but eventually it will drop back to 0. The channels will move up together for a bit then the left channel will increment less compared to the right.

The mic is working properly. I have not fully tested it but have been able to use Skype with it.

My guess this is a bug or a lack of support. Has anybody got this headset functioning properly? BTW, there is a brainstorm to get more USB headset support. Vote for it here: http://brainstorm.ubuntu.com/idea/3764/
