KyleKatarn: Not to derail the thread but did you test it to see if that "Levels" tab fine-tunes the recording volume? I'm just curious because I really like being able to fine-tune several different sources with the recording control in XP and from what I've read from googling this issue just now, people like me who like that feature in XP have been frustrated with Win 7. It's an issue I wasn't aware of and it kind of put a damper on my enthusiasm for upgrading.
It has been awhile since I've used XP, but I think actually like the sound control in Windows 7 better since I can adjust the volume for each program individually (at least while the program is running... I don't think it remembers settings between runs).
Here's the screen I'm talking about for reference:
Note: I don't have a mic plugged in for the screenshot, but the concept is the same as I remember XP (I think),
I realize I didn't exactly answer your question. I don't have a mic to really test things out.
I don't know if that will affect the recording volume or not. That might also boil down to the sound card, too.
