I experienced a popping/cracking sound during recording and playback when using my Sound Blaster Live! on my Win98 system. Why is this so?
This problem happens when you are using a VIA motherboard with either Apollo VP3(VT82C597) or Apollo MVP3(VT82C598) system controller chipset with a VIA IDE Bus master driver version 2.1.33 update. To remove the popping/cracking sound, follow these steps: 1. Run SETUP.EXE of the VIA IDE Bus master driver version 2.1.33 again. 2. Select the Enable/Disable (Ultra) DMA option instead, and then press the NEXT button. 3. Unselect/uncheck the available devices, and then press the NEXT button. 4. Reboot the system Please check
