My sound is choppy while listening to DVD's and CD's. If I copy the DVD or CD to my computer and then play it the sound work just fine. Both CD and DVD games work on my CD/DVD player. I think that the problem is either with my CD/DVD player or my sound card, but I don't want to go out and buy any new hardware until I know what the problem is. I use Windows XP and the 'Sound, video and game controllers' devices that are listed in Device Manager are: Unimodem Half Duplex Audio Device, Ralted AC'97 Audio for VIA ® Audio Controller, Audio Codecs, Legacy Audio Drivers, Media Control Devices, Legacy Video Capture Devices, Video Codecs. If any further information would help please tell me. Thanks

I may have had the same sound problem -- I discovered that my problem was that the DVD drive was reverting to PI0 transfer method rather than using DMA. The PIO transfer method can give choppy or "thumping" audio from both CD's and DVD's.

On Windows XP If you go to the "System" control pannel, then "hardware" then "device manager" then "IDE ATA/ATAPI controlers" then double click on "primary ide channel" (also be sure to check "secondary ide channel") then "advanced" and see if transfer mode is DMA or PIO. If it is set to PIO it may be hard to change back. There is a page that describes how to force PIO to change it back to DMA at: http://www.michna.com/kb/WxDMA.htm

Good Luck!
