What are usual maximum output frequencies on computer sound cards?

Why is my sound stuttering?

• My dad recently talked me into trying out a new video card in my computer. Due to its dimensions, we had to switch the cards around, but ultimately decided it wouldn't fit. After hooking everything back the way it was, now for some reason the sound on my system starts to stutter and won't stop. At least, not until I stop the program or switch the output and back. Also, Cakewalk Home Studio has started acting weird with audio or even MIDI sometimes, and crashes every time I try to play audio or check the MIDI settings. I've tried various things, like re-installing the sound drivers and disabling certain devices, and NOTHING has worked! In researching I looked at my IRQ settings, and it turns out that my sound card, capture card, video card, and network card all share the same IRQ. Does this have something to do with it? Unfortunately, I can't seem to change the settings under Windows 7. Any ideas?

• Answer:

  Yes sometimes IRQ can cause problems like this. IRQ settings are adjusted from within the BIOS, not Windows. Otherwise, yes the annoying answer, try reinstalling Windows. I have done similar work to you many times. When reverting back to original hardware config, Windows is just never the same again, crashes or runs slow.
