I've just finished putting together a new system for a friend, and have come across a wierd problem with the audio. It plays back fine in games, but there is an issue with music playback in windows. When I start playing MP3's it starts off fine but then after 20-30 seconds Winamp (or windows media player) just freezes up and no more sound comes out. I can't close the playback program unless I use task manager, and even then it won't end the process no matter what I do. At that point the whole system is just on a major go-slow and won't even shut down properly. Incidentally, I've not been able to repeat the problem with Audio CD playback, but it happens on almost every MP3 I play regardless of the program used. I've got exactly the same problems under WXP and x64 so seems unlikely that its a driver issue (although I am using the gigabyte drivers for both installs). The system spec is as follows: Gigabyte GA-K8N Ultra 9 Athlon 64 3000+ 160GB SATA Maxtor HDD PNY GeForce 6200 w/256MB RAM 2* 512MB Corsair Value PC3200 Onboard ALC850 AC97 Audio codec Has anyone got any ideas or suggestions what may be behind this, as I'm really stumped and am ready to tear my hair out about now.
