Well, The Sound of my computer keeps Cutting in and out and i don't know what to do its affecting all my games including TB.

Try the simple things first. Are all your speakers/headphones plugged in? Will changing out the speakers fix the problem? If that fails to solve, have you made any changes lately effecting audio? if so roll back changes.

Well I did have my music up a bit loud it may have messed up the Speakers.
