Rabies: Yeah, I'm sure that the pops are from something other than a hot input. I tried turning down the record level and experimented with different things but it still had pops.
I thought changing the video driver was a weird solution, but after reading every faq, readme, troubleshooting, file I could find, and trying all the other (what I thought to be) more likely causes,
irq problems, hardware acceleration, etc...I finally gave in and tried a generic video driver because of a technical note in one of the troublshooting docs. that said to try using a different video driver. Well, I tried it, and the pops disappeared. Of course, things have a way of seeming fixed, and then popping up later on this computer, but I recorded a bunch of things with the generic video driver and never heard the problem. I switched back to my regular driver and then there were pops in the audio again.
I think it the problem has something to do with the way Guitar tracks communicates with the hardware. I noticed that both Cubase, and n-track mention an Asio driver, where Guitar tracks uses Direct x.
I agree with you about this soundcard, it is really nice!
The thing I like about Guitar tracks is that it works like a tape player. It's set up like a regular mixing board with effects sends, etc...for each track. It only has two views to work with, mixer view, and edit view. You have all of the controls you need right there without having to change menu's etc...too bad it doesn't seem to work like it should.
