2940U2W and SB Live! sound problems....
I'm using an Adaptec 2940U2W and SB Live! MP3+ on an Abit KA7. For the most part, things run smoothly. However, whenever I'm using any device on my scsi card and playing sound at the same time, a horrible static is generated.
I'm using an Adaptec 2940U2W and SB Live! MP3+ on an Abit KA7. For the most part, things run smoothly. However, whenever I'm using any device on my scsi card and playing sound at the same time, a horrible static is generated. If I'm running a drive on scsi by itself, or just sound, there's no trouble. Any ideas what might be causing this, or how to deal with it?

Sound like a classic sb live hardware conflict. With my machine it did the old painfull to the ears screeching static whenever I used D3D and played a digital sound. I'm sorry to say that no amount of experimenting over a 4 month period could fix it once it started. Tried everything from different mb's and video cards to reinstall of win2k. Nothing ever fixed it.
My theory is that some part of the sound chip grabs a motherboard resource, but doesn't tell it. Therefor the board thinks that the resource is free and gives it to another card or takes it for itself. The reason that Win98 doesn't have any problem is that the OS manually allocates this 'hidden' resource when you install the live drivers. It then forces the motherboard to not use the resource for any other card by using the OS's PnP controller. Basically, I think that every time the Win98 boots, it moves whatever the board has placed at this resource. The Win2k drivers don't seem to have that ability.
I finally solved it by getting a SB128 (1373). Sorry that I don't have a solution, but I was forced to give up on it. And believe you me, I don't like to give up at all! Four months I fought that damn card

It just occurred to me: I had no audio problems when I'm playing dvds of my scsi dvd drive...yet I have problems everywhere else. This is getting weirder.... The static isn't constant, though. It comes in little bursts. I was watching 2001: A Space Odyssey with no problems. But copying data from a disc or hd causes it. Damn, this is odd. No matter how much tech experience I get, something weird that beats all your knowledge will find it's way to you....
