Just in case this fixes the issue for anyone else.

I had av sync issues with 24p content for the longest time - but for me it was resolved in 13.0. BUT ONLY if I use these settings:

enable adjust display refresh rate to match playback
and enable Sync Playback to Display
and use A/V Sync method Audio Clock

I am bistreaming audio to my Yamaha AMP using wasapi.

If I disable A/V Sync then the issue comes back.

Pressing o during playback shows a missed counter which increments by 1 or 2 per hour, or if I pause it runaway increments until I resume playback.

I'm using an AMD 5450 graphics card.

FYI - the above settings which worked for me in 13.0 and 13.1 no longer work in 13.2. Back to 13.1 for me.
