AccessViolation in ASIO module

[mc0re]

When opening an ASIO control panel twice, the second time it produces an access violation exception. It cannot be caught by Visual Studio, so I had to use windbg to get this information.

that looks like code in the WASAPI APIs rather than anything to do with ASIO. Are you using any other parts of NAudio?

I query all possible sources, including WASAPI. But I didn't use WASAPI for playback.
