hi. i can't find the correct driver for my audio device. i've got windows XP home edition, the one i need is 18.104.22.168. other codes listed are very similar and i installed one of these thinking it might be an upgrade. however its no good as the sound although now playing for the first time,is speeded up , with vocal sounds sounding like they've been sucking heliumj. Can anyone tell me where to go next?
