Comment 11 for bug 378334

The volume control used to work fine under Karmic, but upgrading to the Lucid beta broke it. If I plug in my Logitech USB headset, the audio switches to the headset, but the volume control continues to affect the Internal Audio device. When I go to the Sound Preferences, the Output shows the Internal Audio device is selected. When I click on USB Headset in the Sound Preferences, the volume control starts working for it again. If I unplug and replug my USB headset, the volume control once again remains on the Internal Audio device although the audio goes to the USB headset.
