I have just installed a M810 L 7.1 mainboard with 1.2 gig amd k-7 cpu. The board has onboard sis 730 chipset with all peripherals built in. I have reinstalled multimedia drivers several times, and cannot get any audio. The OS is Win98, second edition. Any suggestions how I can get the multimedia to play sounds? It appears to be playing, yet no sound. I have tried even plugging speakers in to all the external jacks, yet to no avail.
