I am having a very strange problem. I have perfect audio when I am playing music or video from my hard drive, but if the source is a cd or dvd, the sound is slightly distorted and jumpy. It is a new computer and all my drivers appear to be working, up to date and compatable. I am using a tdk dvdrw1612dlb. XP home, gigabyte motherboard with built in sound card.

I also cannot rip a cd and listen to music at the same time. As soon as I start ripping, the playback becomes distorted. Never had such problems on my older more basic computer.

Any ideas would be very much appreciated.
