I have a Creative Sound Blaster Audio PCI 64V on board chip. Since upgrading to Windows Me I have very bad crackling on record and playback. Also there is no sound from CD on headphones. I have checked the lead from CD to Motherboard and it is OK. Sound is worse when mouse clicks or application running. The driver I have installed is mmdevldr.vxd (4.90.3000) Please can someone help
