I have the following set up:
- Atom/ION 330
- Windows 7 32 bit
- latest nVidia drivers 260.xx - desktop res 1920x1080 @ 50Hz
- latest SVN Dharma RC
- True full screen
- Aero OFF
- Auto adjust refresh rate ON
- Sync playback to display ON & sync method "drop/dupe audio"
When I play 24p material (I should say, 23.976 Hz), the TV nicely switches to 24Hz and I can now most of the time (but not always!) get perfect lip sync - without the 'patch' mentioned prior in this thread.
History
- I did not experience this sync issue as long as I was sticking to the desktop refreshrate of 50 or 60 Hz (with Auto adjust is OFF).
- The issue started when I started to use Auto adjust refreshrate (to benefit from TV optimization for 24p video)
- With "sync playback to display" turned OFF I was getting the audio sync issue almost everytime for 24p material. I experimented with the patch to always have 250ms delay in this case, and it worked fine.
- Now with "sync playback to display" turned ON (and no patch), there is still a minority of videos where I get a ~200 ms out-of-sync issue. Generally in those cases, I see a rapidly increasing vblanks "missed" counter.
What info do the devs (bobo1on1) need to get to the bottom of this? Thanks!
