This does not make sense - as we want to guarantee that exactly the amount of swap buffers is met that refreshrate is giving us. You mean "Adjust Refreshrate to match video" right above?
a) Can you try what happens with: vsync turned on, method video clock and resample audio? - you need to disable passthrough completely for this test. Is that better or the same bad?
b) Can you try: vsync enabled, "Adjust refreshrate to match video" disabled(!), Sync Playback to Display enabled with method video clock and resample audio?
Thanks for the feedback.
Aero does triple buffering which is hard to get in sync if the video clock is using swapbuffers as a measure.
To confirm Torcar's findings I reported this earlier in the thread. Switching off vsync provides perfect audio playback - no need for latency adjustments, though obviously introduces screen tearing. Switching on rids playback of tearing but introduces audio latency issues.
