You have been subscribed to a public bug: Repro: plug Logitech C270 (one I have) webcam in USB port (others with builtin microphone are affected most likely)
Expected: device hooks up and works properly Actual behavior: pulseaudio becomes unresponsive (totem freezes, volume controls work with huge delay, sound is not played at all), dmesg becomes flooded with messages like "7:3:4: cannot set freq 48000 to ep 0x86" After unplugging webcam pulseaudio becomes responsive again.
