Comment # 9 on bug 1181097 from J���rg K���hne

Hi,

I have the same issue with my Logitech webcam C270. No microphone available in
pulseaudio. If I boot the older kernel, everything is fine.
In alsa the microphone is detected.

arecord -l :

**** Liste der Hardware-Ger���te (CAPTURE) ****
Karte 0: PCH [HDA Intel PCH], Ger���t 0: ALC1220 Analog [ALC1220 Analog]
  Sub-Ger���te: 1/1

I can record my voice via

arecord -Dhw:2,0 -f S16_LE test.wav

But 'pacmd list-cards" and pavucontrol do not list the USB device.

Thank you
