Audio in media files randomly glitches and sometimes repeats for 1-2 seconds and then continues playing normally. These glitches seemingly happen at random times and don't recur in the same part of the audio tracks.

These glitches did not occur on Fedora 17 nor on Windows so there is nothing wrong with the hardware nor the files themselves. Tested on various media players.

I'm trying to fix this problem by installing the same audio drivers/software as Fedora has, but I don't know where to start.

Edit: I'm using GNOME 3 and I've found another audio-related glitch. It occurs when the mouse is moved to the top left corner and all the open windows are shown or when the start key is pressed (the same "GNOME menu" opens). These glitches are not of the same nature but this never happened on Fedora 17 either.

Also on 12.04 I have noticed this too. –  Captain Giraffe Aug 22 '12 at 22:01
