hrmm, when you say the software was bad, do you mean you didn't like the way it was performing, or were you having functional problems with it ? what audio card do you use, and what kind of computer / laptop ?
this sounds similar to the realtek problem , in the sense of having multiple drivers fighting for resources.
don't quote me on this because im not tech support, just a user trying to be helpful, but Im guessing you may have a driver conflict issue thats causing your system to act strange.
the solution might be as simple as removing your drivers and reinstalling only the ones you need. You may have old drivers in your current mix, but check with someone else on this first please.
