Windows 10 Anniversary update with a creative card by any chance? I get it with my Soundblaster Z and it's Windows 10 that keeps changing the audio source. It's only been happening since the anniversary update. I disabled every option in the sound settings apart from the Soundblaster Z and it hasn't changed the source since I did that. I still get that message about the enhancements but only when I go into the windows sound settings and then it asks if I want to re-enable the enhancements. The latest Creative driver didn't fix this so it's a windows problem.
No issues with my sound blaster z and latest version of Windows 10
