If your getting distortion when you open Skype, and/or distorted sound when Skype make a notification sound, read on …..
Go to Skype – Options – Sound Devices. Un-tick “Allow skype to automatically adjust my mixer levels”
If your STILL getting distortion open a command prompt and type
sudo nano /etc/pulse/default.pa
Add tsched=0 to the end of the line that reads ‘load-module module-udev-detect’ so it looks like…
load-module module-udev-detect tsched=0
Save (CTRL-X – Y – Enter) and reboot.
Your good to go.
