How do I fix the weird Skype noises?

How to fix the weird Skype noises on Raring? It sounds completely distorted.

I tried a guide from askubuntu.com so it ruined my pc so I reinstalled Ubuntu but how do I fix the weird noises?

Here it is: Skype and VLC sounds sizzle/distorted/bad

Edit /etc/pulse/default.pa and add tsched=0 to the line load-module module-udev-detect

sudo gedit /etc/pulse/default.pa
                     load-module module-udev-detect tsched=0
                     load-module module-detect tsched=0 

Save and restart pulseaudio

$ pulseaudio -k
$ pulseaudio --start

Source

It should look like this

load-module module-udev-detect use_ucm=0 tsched=0
.else
### Use the static hardware detection module (for systems that lack udev support)
load-module module-detect tsched=0
.endif
