How to resolve the audio distortion in Skype on Ubuntu 13.04 and previous versions

If you have problems with Skype audio on Ubuntu (distortion, croak, noise…) the simple way to get it fixed is editing the file /etc/pulse/default.pa, change one line and restart the system.

From: load-module module-udev-detect use_ucm=0

To: load-module module-udev-detect use_ucm=0 tsched=0

For simplicity you can execute the following command that will do all the job:

sudo sed -i "{s/^load-module module-udev-detect use_ucm=0$/load-module module-udev-detect use_ucm=0 tsched=0/g}" /etc/pulse/default.pa

Restart now the system and the Skype audio should work fine!
