I have no doubt its something Delta 1010 MAudio related....
MAudio cant write drivers for toffee.....
I'm using the 5.10.0.5076 drivers as the latest Win 7 Drivers wont let me change Sample rate from 44.1 no matter what!
For reference the latest Win 7 Drivers and Sonar still crashed anyway....
I did try all the usual things guys, like when Sonar crashes, kill all the Maudio processes, Windows Audio Service, everything Audio related basically but still SonarPR.exe wont free itself up.
But guys, Sonar is the only bit of software I have ever used that behaves like this after a crash.....
