Hey Dfaris,

Good info here for you! I'd like to add my 2 cents>

First, I have a used laptop I just bought for live gigs. It has win Vista and I am having one HELL of a time getting it to work with BIAB and Sonar. I remembered all the issues I had with Vista years ago when it first came out.
My main PC in the house has Win 7 32 bit and it just WORKS! No issues with my EWI wind controller and USB midi keyboard controllers. You have a decent interface, I had that cakewalk model for a short while and it worked fine for me. So, think about the following>

1. Go to the Cakewalk site and try to find the specific OS drivers for your model using Vista SP3.

2. If you find that you are actually using XP or Vista SP 1/2 drivers, first uninstall the driver on your machine, then right click the install file, choose the compatibility tab, and then choose either XP or Vista and also check "Run as Administrator".

3. As Mac suggested, make sure you know the difference between your onboard soundcard settings and your Cake interface settings. This MAY include some boring manual reading but in the end will pay off for you. Some users disable their onboard soundcard all together, this is a good way to keep from seeing confusing error messages or track down issues.
4. If all the above still isn't resolving your issues, I would seriously consider upgrading your OS to Windows 7 32 bit. Like I said before, it is working great for me. Also, I believe Cakewalk now has Win 7 drivers.

Keep us updated, I'm sure plenty of other users are going through the same type of things!
