fwiw
I had major issues with sync of audio when "Adjust display refresh rate to match video" was set. It was only happening on one TV (Samsung LCD) and not on my other telly (Samsung Plasma). It would drop frames like crazy! I discovered that I had set "Deinterlace Video" to "On". Changing it back to "Auto" has fixed the issue completely. I have "Sync playback to display" set to "Video clock (Drop/Dupe audio).
I run at a default of 1080 50Hz (NZ broadcast DVB-T at 50Hz) and I now auto-adjust to 1080 24Hz (or whatever the source video is) and it is perfect. I am running my own build from "Master" on September 8, 2012 post the merge of PVR code. I have live tv working perfectly using TVHeadend and now ALL content is running buttery smooth with perfect audio sync.
Both cards are Nvidia. One is native HDMI while the other is DVI-HDMI cable. Audio in both cases is via SP-DIF via the onboard audio of the motherboard (both optical and via a shared 3.5m port).
I am running Debian Testing and compiled using gcc 4.6.
