Skype sounds audio distorted in Ubuntu

Now that I have Skype installed on Ubuntu 13.04 I discovered that the various Skype sounds were distorted.  It was almost like the sounds had some static mixed in with them.  I thought it was probably just a problem with the new version of Skype, or the new sound drivers.  However, I made a discovery that fixed the issue.

I tried the AlsaMixer fix, but it didn’t work. (A reboot simply resets the PCM to 100 again, and the sound is still crackly.)  So it all came down to a simple file edit to get it fixed.

Edit the file /etc/pulse/ using the command:

sudo gedit /etc/pulse/

Add the following to the end of the line shown:

pulse audio file

So after adding “tsched=0″ to the end of the line “load-module module-udev-detect” you will be all set.  After a reboot the sounds is still good.

Enjoy!  Hope it works for you.
