Im having audio issues from my laptop and recorded this last night http://soundcloud.com/dave71/audio-issue
i recorded it using my dj software so its taken directly from source. It intermittent as i can reload the same track and play it without the stuttering
Hdd reading issue, ram writing issue.
It generally comes to light after a couple of hours but is intermittent, the next song could be perfect. definately not related to my sound cards etc as i have swapped every external piece of equipment
Obviously try dismiss the fact its a god awful crap track to start with and just listen to the audio
I eat kebabs when i'm sober!
