output moves to usb headset, but volume control doesn't

[sam tygier]

if i plug in a usb headset (logitech A-5572A) and play some music with rhythmbox, the sound comes through the headset, but the volume control in the indicator applet (or the volume hotkeys) seems to still be controlling the built in speakers.

if i open sound preferences and select the USB headset in the output tab, then i can control the volume though the gnome controls.

i would expect the volume controls to always effect the currently active output device.

i guess this is a bug at a higher level than alsa, but i wanted to make sure that ubuntu-bug uploaded all the sound info.

This is a known issue and needs to be addressed upstream due to divergent approaches to code changes in the sink & source callbacks.
