For software, I'm using Cakewalk Music Creator
Pro24 2004. I don't know if you're using that, or if you're familiar with it or not, but here are my audio settings in it:

I thought maybe not sharing drivers with other programs would help, but it didn't. I messed with nearly all of these settings to no avail. The only thing that really changed the quality of the recording was the buffer size. You can adjust it from fast (latency of 10 ms) to safe (latency of 340 ms). Safe sounds a lot better than fast, but even all the way over, and with Buffers in Playback Queue set to 16 instead of 2, I still get some popping and clicking, like static.
Also, the IRQ is not the problem. I messed around with hardware profiles and in BIOS until I finally got the M-Audio card on its own IRQ (IRQ 3, I disabled to COM ports, hehe). There was no change in the quality of the recording, so IRQ sharing doesn't affect this card, obviously. It is something else. Should I use ASIO drivers or something? I don't know what my default is, it's just set to "Default."
I'm not quite sure about your setup, but if you think the card is okay, then it must be the setup. Some certain combination of hardware might cause the noises, which needs to tweak a bit to run smooth. Can you post your complete setup again?
WOW!
I should be able to hear it if I save it and then restart and enable the AC'97, though.. If this works, there should be no problems with the recorded audio, I would think. I'll try that.
