Now this thread is derailed,, OP your playback issue sounds like a clock rate change which is common when you change interfaces. But are you using the Lexicon now? 
Or did you find the ASIO drivers for the SB?  Here is what I found-

But it is not clear what the driver is as it does not mention if it is ASIO in the documents.

If you do have the Alpha working you may need to remove all traces of asio4all. There are may reported things that asio4all is not easy to kill 100% and it remains lurking somwhere causing issues. And to make matters worse, Creative drivers can also lurk. 
When I bought my M audio Fast track I had to remove the SB card and re install windows to set things right. 
 
The trick to Creative is to ONLY install the basic driver and in no way install ANY of the other software that comes with it. It's this bloatware that I believe is the cause of the grief. 
I am having no problem with this office computer and all the ins and outs work fine and I didn't install anything but the driver. If you get the Creative splash screen your in trouble! I forgot how bad it can be because it's been a long time since I used this card. You gotta admit the DVD tray breakout box is mighty handy. Not sure what the Firewire port does. At the time I thought I was buying the best money could buy...I'm sort of happy to get it to work again if only for listening to MP3's. Nice to know I can use it as a basic DAW too. Plug your guitar right in to the front. There's even a remote!

Another good budget choice would be the Steinberg UR-22. I use it, and being a hobbyist it is all I need and I have no problems with it. It's a USB.

One of the most troublefree interfaces i have owned. I got it as a portable solution and it has been rock steady

thanks for all your help. I do not have a Lexicon. I searched and searched and I do not think my current Audigy FX soundcard is ASIO compliant. It isnt a hi end thing at all... I got it at Best buy for about 20 bucks, a long time ago, so I'm not surprised.
 
I ordered the Audigy RX, for 50 bucks, with ASIO drivers. It seemed to be to good of a solution, to not try, before spending a lot of money on something I might not need.
 
I guess before installing it, I must un-install the drivers and all the software, for the existing Audigy card? And also uninstall ASIO4All. You mentioned that was difficult. Any steps you recommend?
