I think there's a problem with my sound card / driver. Every so often when i click mouse (usually in internet explorer or itunes) a loud buzzing sound comes from all speakers. So i immediately turn off the speakers, and when i turn them back on there is no sound for approx 30-40 seconds, but also an mp3 track will not play (while sound is muted) until the sound comes back on.
I'm running windows vista 32bit with soundblaster x-fi sound card.
Ive searched for latest driver in the device manager but it says i'm using the current driver.
