I ran some tests and here is what I found: I can record normal sound from webcam's microphone, but only once after reboot. Any subsequent attempts will record high pitch garbage. I've also noticed that track duration counter in gnome-sound-recorder lags (one second in counter is like 2-3 normal seconds) as well as input level indicator. There is also noticeable sound glitch when starting first (normal) record, so maybe this bug is not about the kernel but pulseaudio's fault.
