Title:
pulseaudio stops responding after plugging Logitech webcam in
Status in “pulseaudio” package in Ubuntu:
Confirmed
Bug description:
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.
