I got a Logitech Quickcam Pro 9000, the cam itself is working as it honors the UVC spec.
This fancy WebCam has a integrated mic which worked some time before but now, it does no more. (Note: I use pulseaudio as it is a USB Mic and I am not really keen on the hassle of ALSA setup)
Things I check already are if it gets detected at all:
$ lsusb |grep Logi Bus 002 Device 002: ID 046d:0809 Logitech, Inc. Webcam Pro 9000
is not muted in alsa-mixer, volume at 100; pavucontrol shows it too, but no input level bar!
On top of that, if I open the gnome3 (fallback mode) audio panel (from the desktop panel), and disabel/reenable it in the hardware tab, it works "for some time".
Any hints? Any ideas? I am really out options for now, and the fact it worked like 6 months ago (perfectly) makes it no better.
