Created attachment 63705 [details] Uninitialized memory fix for XAUDIO2_VOICE_SENDS*
I believe the crash is due to an uninitialized pointer sending bogus data to our send wrappers, does the attached patch fix the issue? It works for me, but I could be missing more variables...
I tested the demo (requires native d3dcompiler_47) and can confirm the crash. Your patch fixes the issue for me.
