Comment 5 for bug 877789

I can confirm that it also affects ATI/Radeon users as well. Playing audio of any kind, whether from Firefox, Banshee or Totem the audio is quite choppy. It does not appear that CPU load is a contributing factor. What is a contributing factor is keystrokes and mouse movements. A pop can be heard for each keystroke or mouse movement. If I hold down a key or drag my mouse across the screen the audio chopps. It definitely appears to be an issue within xservers or its driver sets as I installed fglrx, AMD's proprietary graphics driver, and the problem disappeared. Upon removal of fglrx the problem returned. Also I should add that I did not experience this issue in Natty.
