no problem, ulcer123,
for your system specs, check out this link:
System Info - See Your System Specs
for the other info, i'm sorry but i forget exactly where in protools you select the audio
driver - it's been so long since i used it.
check your windows control panel >> sound to see what the default windows playback device is.
i'm off to play skyrim for a bit, then i'm off to bed, so i won't be able to reply to you for a good few hours, but if you can supply the above info, there are many other knowledgeable forum users who may see this thread and will be able to offer you some help before i get back.
