I have in fact recorded Black Ops 2 with Bandicam, and I haven't gotten this issue. Might be your sound card/Windows settings.

Download and install Bandicam, after installing open up Bandicam and go to the 'About' tab. Click 'Register'.

I believe he already unchecked that.

Just letting you know, Bandisoft team rarely ever replies in the weekends, so since you bumped this on Monday (today), it shouldn't take them long to reply.
