I haven't been able to get audio on my webcam for a while. My initial guess is that it has to do with all of the udev changes.

I'm using gnome w/ pulseaudio. The audio properties show the device on the input tab, but it doesn't detect any activity.

what is in your `Configuration` tab after running `pavucontrol`?

i had trouble getting sound working consistently until i realized i had that on the wrong device ... even though it seemed like the "right" choice.

I have:

RS880 Audio Device [Radion HD 4200]        Digital Stereo (HDMI) Output

Hercules Dualpix Exchange        Analog Mono Input

Internal Audio        Off

when I turn the input volume all the way up in both places, I think I can hear something slightly. If I do a Skype test call I hear a lot of white noise and some faint tapping if I hit the webcam.

I suppose it's possible that it's actually using the wrong device somehow, but there are no other mic's that I know of on this desktop =/ I don't think there's one built in to the HDMI monitor.

hmm yeah i don't know a whole lot about it :-( after enough tinkering i just got my to work finally and never looked back ... mine had lots and lots of "profiles" for each device, of which only 1 or 2 worked correctly (mainly because i didn't have the equipment to support the others, eg. 5.1/7.1/etc) only other thing i could suggest, and maybe you already did this, but make sure your devices aren't muted in `pavucontrol`, have volume (== input sensitivity for mic IIRC), and make sure appropriate devices are flagged as the default/fallback -- this is all in `pavucontrol`.

Hmm, it may or may not be related, but downgrading to 2.6.38 certainly solved the problem. I'll continue the discussion of the forum. Thanks!
