Hello. On my Dad's computer, XP professional, quite a low spec 500Mhz AMD CPU thing whenever he plays an audio CD it 'crackles' (his description).

On investigating this it appears the PC plays audio via the IDE bus, and as it's a lowly machine every time the HDD is accessed, the audio get interrupted which causes the 'crackle'.

There is the usual audio L+R cable running from the rear of the CD to the audio input socket on the motherboard but how do you persuade the CDROM drive and/or windows to stop using the IDE bus and just play via the audio?

Weird!

Thanks for any help.

The problem is the sound card/chip.

The remedy is to not use the onboard sound chip (which is CPU-intensive, of necessity) and install/use a PCI sound card which is not CPU-intensive.
