SoundBlaster X-Fi Crackling and Popping Update from Creative
 

Further to the reported cases of crackling issues reported by owners of Sound Blaster X-Fi cards, we have extensively tested both Creative and non-Creative audio cards on motherboards where the issues were reported in an effort to isolate the root cause.

The findings indicate that circumstances causing these audio glitches only arise on Nvidias nForce 4 range of motherboards, with the exception of the newest n590 board which does not exhibit this issue.
