Ubuntu – Ubuntu 12.10 Skype webcam microphone not working

12.10microphoneskypewebcam

This is making me crazy.

After upgrading to Ubuntu 12.10, Skype 4.1.0.20 can't use my web cam microphone anymore.

  • I can record correctly from the web cam microphone using the sound recorder
  • the web cam microphone is selected in the global sound settings and working in any other application.
  • Also tried to start skype with LD_PRELOAD=/usr/lib/i386-linux-gnu/libv4l/v4l1compat.so /usr/bin/skype and LD_PRELOAD=/usr/lib/i386-linux-gnu/libv4l/v4l2convert.so /usr/bin/skype

No matter what, Skype will keep using the front panel microphone for audio capture. Mic was working fine with Ubuntu 12.04 before I upgraded to 12.10.

Solved with pavucontrol. I had already tried the pulseaudio volume control, but you need to do a particular thing to make it work.

First, install pavucontrol:

sudo apt-get install pavucontrol

Then start it:

pavucontrol

You'll get the volume control window. Now, you could go to "Input devices" and select the webcam microphone as your input source: THIS WON'T WORK. This is how you do have to it:

  • Click on the "Recording" tab. This tab shows the applications that are capturing audio in that very moment, so it will probably be empty.
  • Start skype then call the Echo / Sound Test Service (or anyone you like who will answer)
  • When the other party answers, Skype begins capturing audio and will be shown in the "Recording" tab of the pulseaudio volume control window
  • From the "Input from" drop down list, select your webcam

And voilà, you'll get your microphone back.

Alternatively, as described in SkypeTroubleshooting

  • [..] go into the Skype Options menu - Sound Devices
  • remove the tick at: Allow Skype to automatically adjust my mixer levels.
  • Click Apply.
  • Readjust the sound mixer controls (pavucontrol input devices will work now).

This worked fine for me.
