A while back I 'upgraded' Sound Forge Pro from the Sony Release to the latest Magix. I also bought Camtasia Studio 9 for recording YouTube videos.
 
Both of these muck around with audio and take over the system in various ways - Magix loads an ASIO4ALL-type driver and Camtasia does not support ASIO.
 
So I found out how to load the Fruityloops WASAPI2ASIO driver to further complicate things.
 
To make a long story short - very few people seem to understand audio like the Cakewalkers. I'd blame them last for any problems I encounter.
