Just got a "Trust" webcam, which gets recognized on my Ubuntu Lucid. It has a built in microphone - which also gets recognized - however, I cannot really get it to act as the system microphone input?

Here are some screenshots of what is shown by gnome-volume-control:

The default window shows Trust webcam - which has two profiles: "Analog Mono Input" and "Off" - of course, I have it on "Analog Mono Input":

However, on the "Input" tab - there is no matching "device for sound input" - neither a matching connector:

Then I installed pavucontrol - but that doesn't show that much more; it tells first that gnome-volume-control reads from "Internal Audio Analog Stereo":

Then in "Input devices" tab, there is again nothing resembling the mic input from webcam:

Finally, under "Configuration" tab, the "Trust" webcam shows, but even if its profile is on "Analog Mono Input", nothing much happens:

So, does anyone know how I could get this webcam microphone to be recognized as the system input?

Many thanks in advance for any answers,
Cheers!
