You can also enable "PLL adjustment to maintain audio sync" which attempts to do this without resampling which does allow passthrough,
but the amount of adjustment possible is less so it is possible this won't work satisfactorily (e.g. trying to adjust 24fps video to 50Hz display).

Thanks I wasn't aware of that compromised solution. I might try it out .

We can be watching for ages and nothing will happen and then the picture pauses for a few seconds whilst the sound continues but after that few seconds the picture then catches up.
Sadly enabling sync playback to display no longer seems to enable DTS audio pass-through for sound.
It didn't use to happen but again due to the randomness it is hard to remember when it did start.

Yes indeed. I have been trying to get something repeatable so that this could be investiated deeper, but it is illusive. Does seem to be both settings and video dependant though, just not exactly sure what combination.

I too have been trying to find something repeatable, like you note. As yet I haven't been able to. Last night it happened, the video paused for a few seconds and the audio continued and then the video starts starts back up, jumping to be in sync with the sound.
For ages I thought that it was kinda unique to my system as I searched for "pauses" and not "stutter". I'm not drawing comfort that others can be affected but perhaps that might increase the chances of one of us capturing a meaningful log for the Devs to look at.

Yer your not the only one, I've had this problem, but it fairly rare for me to see it.
The only thing I did notice was last time the picture was freezing my memory usage was in the low 90%, not sure if this was causing the issues though.
Will also try and get a log but I'm not hopeful as its so rare these days.,

I'm also having this problem. I saw it when running alpha3, then it disappeared in beta1, but now it seems to be back again in beta5. Due to the randomness of the problem it might have been there the whole time though, maybe related to the video files I am watching.

I was never able to reproduce it with debug logging for the video component turned on, maybe it should give it some more tries.

I think all my settings related to sync are on default.
