From someone who struggled with the SB Live 5.1/Via 686B issue for a few weeks, I would suggest a different soundcard. Believe me I tried everything to fix the issue on my A7M266; changing PCI slots, BIOS fixes, 4-in-1 patches, etc. and nothing fixed the problem until I just broke down and got a Philips Acoustic Edge soundcard. It has worked flawlessly and sounds great (includes 5.1 sound also).
I know a bunch of people will think that I didn't do something right or flame me because it works on their system, but I know from experience that all of the SBlive!/Via 686B problems have not been worked out. The funny thing is that my SBlive Platinum 5.1 worked fine for a couple of months, with only one episode of drive corruption with an old TNT2 Ultra. When I switched over to a Hercules 3D Prophet III (Geforce 3 model) was when the corruption really got bad (like every day or two). From searching around on some of the boards and FAQs (www.viahardware.com was helpful) it appears that having an nVidia card sometimes seems to amplify the corruption problem between the SBlive! and the Via chipset. It's very odd and flakey and appears to occur somewhat randomly while playing games. Who knows, my Adaptec 2930CU SCSI card may not have helped the problem either. Between it busmastering, the IDE working on DMA, the SBlive working through DMA, and the graphics card being bandwidth hungry, I ended up with a nasty brew that was nothing but headaches. Like I said, though, going with a different sound card cured all of it instantly.
I've used Soundblaster cards for over ten years and will still suggest them for people with Intel based systems. I know they are the "reference standard" but I also know my experiences with them. Even people with Intel systems have sometimes reported DMA problems with the SBlive like stuttering or crackling during game play. My feeling toward Sblive! cards and the Via 686B problem is that it is like a time bomb waiting to happen. A change in video cards caused it to appear on my system.
I've also heard several good reports from people using the Turtle Beach Santa Cruz card which is also supposed have really clean sound.
My 2 cents anyway.
