I have two K7S5A mother board with the latest Bios upgrade.

The problem? Popping sound when playing a DVD movies.

I have two computers nearly identical Same k7S5a and Athalon 1800 CPU. Computer A uses the On board sound (SIS), Computer B uses a sound blaster live card. and both have over 500 mb of ram and plenty of disk space. both are running XP Pro.

When playing back a music CD the sound is perfectly clear but the DVD sound is garbbled and there is a back ground popping noise.... I took the drive out and put it in a known good system and the DVD sound was perfect so I know the DVDROM drive is fine.

It can't be the sound card or the on board audio...because they produce the same kind of back ground popping.

The Drives are set up Master Slave. The Master being the DVD and the slave being the writer.

I am at a loss her folks...Could it be possible that two mother boards could be bad?

as a side notes:
1. the picture quality is perfect.
2. I used different DVDs
3. the poping noise does reduce when turning down the treble. But the audio is very garbeled...
4. when playing an Audio cd the sound is loud and clear...when playing DVD the sound is low...abnormally low.

Thanks for any help!

the on board sound sucks. If i move the mouse when playing mp3s i get static sounds. try not moving your mouse.

sounds like you have a irq conflict. find out what devices are sharing the irq with your sound device. the bios assignments of irq's are "poor". you may have to shift around cards or disbale unused devices to free up irq.
