Beetle HW - audio randomly de-syncs/state loading fixes it

So in the latest RA Feb 3 2019 build with Beetle HW 0.9.44.1 playing SH with GTE or CPU OC will at random times start desyncing audio (cracking). Vulkan + Win7.

Saving a state, restarting RA and reloading it fixes it, so I don’t believe it’s due to my PC not being able to handle the emulation (using slight OC to get stable 30 FPS internal).

This can occur between 15-45 mins of playing, random locations. Again, loading a state in that exact spot fixes the problem.

Why?
