Having problems with programs like Skype, Viber or Spotify sounding distorted on linux system like debian or ubuntu? Other have tried to explain the sound as jittering, sizzled, robotic, grainy, fuzzy, overdriven, crackling or simply weird.
The solution is rather simple, open the following file:
Replace following line if you are using udev:
load-module module-udev-detect tsched=0
Replace following line if you are using hal:
load-module module-hal-detect tsched=0
Save the changes and restart the computer, all done!
