Windows XP Audio-Driver
If sound is troubled while playing MP3s or DVDs under Windows XP, it is caused by an old driver version located on the CD. This problem does not occur anymore with the latest driver version (see download).

Mainboard-Version

The version's name is imprinted onboard.  (AK31 Version 3.1 has no changed sticker, but it has been pasted over)
