This is making me crazy.

After upgrading to Ubuntu 12.10, Skype 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:


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.

  • for me, unmuting the microphone was enough (under the 3rd tab) – BЈовић Jan 11 '13 at 21:44
  • @f.cipriani thanks for the solution .. it worked for me .. but when i logout/restart, the changes revert .. is there a way to make this permanent? – Abhinav Aug 20 '14 at 13:57
  • Works now on Xubuntu LTS 14.04. – Serge Stroobandt Dec 28 '14 at 16:32
  • Thanks a lot. Apparently skype is changing the input device when starting a call... but with pavucontrol it is possible to switch back directly. – luator Dec 9 '18 at 16:58
