Volume control of my wireless headphone ?

[funicorn]

Hi guys,

I'm using Ubuntu 10.04 upgraded from 9.10 directly. Before upgrade my 2.4G wireless headphone works fine. When I toggle the volume controller (a electronic trigger, not mechanical wheel), the volume goes up or down with a beautiful gnome-osd volume bar displayed. But now the headphone's volume control does not work any more. There is no osd display, and no change in the system volume. Does anybody know why this happens and how to fix it ?

Many thanks.

Well I found the reason. I manually changed the shortcut key of gnome volume rising and lowering. Changing it back to the default value XF86AudioVolume... (for me I toggle the volume controller on my headphone) solves the problem.
