Sorry, but I've seen this happen on every machine I've encountered. There is only one surefire cure, but you left out all the details so I don't know if it will help.
1. Do not use Windows Media Player.
2. Try Winamp.
3. Set the CDROM playback to ANALOG.

When I am connected or trying to connect the internet sometimes when I play music the music stops and an annoying disturbance through the speaker. My modem is C56K Data/Fax modem(internal). My OS is XP and ME. Help me.
