Rare potential crash on starting audio engine with AudioGraph backend

[xris1658]

Description / Reproduce

On rare circumstances, starting the audio engine with AudioGraph backend (which is the only backend YADAW uses on Windows) will crash the program.

Log / Stack trace

Though the actual crash is rare, we can locate this problem on every startup with Dr. Memory. The following log is from result.txt generated after one session:

Note that "previous lower malloc" in MFCreatePropertiesFromMediaType allocated 0 bytes, which is weird giving that it seems allocating audio buffers we'd like to read in the callback.
