I'm having the same issue. Using the following pipeline

wasapisrc ! wasapisink

the sound will play for about 3 seconds and then goes silent.

Unexpected discontinuity in audio timestamps of -0:00:00.040000000, resyncing

I'll try to investigate it later, but would be nice to receive a feedback here.

By settying setting sync=false for wasapisink, the pipeline works fine (the
audio isn't interrupted).
