I just installed a Logitech C310 webcam, on my onieric system, and I have a problem with it's audio. When recording sound from the webcam's source, the resuult is played very fast, in a very high pitch. I believe it has something to do with pulseaudio, since when I tried recording directly from alsa (by using audacity), the result was fine.
EDIT: I checked it further, and the problem occurs only after I switch between different users.
EDIT: I've also found a similar bug reported on Fedora.
