I just got a K7S5A Pro mainboard. Everything works fine except for the onboard sound. I can't seem to get it working, it's like there is a really, really, really low sound whenever I play music or stuff like that and it dissapears when I pull the audio-plug so it's not just some interferense. It doesn't matter how high I set the sound to. All I can hear are faint sounds if I crank it wayy up. I have win98se.
