I'm currently struggling with this motherboard & video/audio sync. I'm running Myth CVS and the latest Alsa and have 3 DNTV Live DVB-T cards installed, 1G ram, sata driver, amd 64 3200+ cpu. I have yet to get as far as using the spdif outputs, although that is the ultimate plan (connecting to my amp). I've spent weeks on this and have yet to get a decent clue to the problem. During playback of recordings, a/v sync is fine, however with live tv, the sync is fine when I first go in, but as soon as I change channels, the audio lags behind the video usually by around 1/4 sec.. but sometimes as much as 2 seconds. Exiting livetv and entering it again will correct the problem. I'm also seeing lots of pre-buffering pauses etc in the logs, I've tried all sorts of settings in myth, all of which just made things worse. Since the mb only has 3 pci slots, I'm loath to go down the soundcard route (being able to watch tv while recording 2 programs or record 3 at once is a nice feature!). FWIW, I'm running Ubuntu (hoary pre-release), a custom compiled 2.6.10 kernel (with patches to enable the dntvlive cards), NVidia 6600GT PCIE video card with the ltest nvidia drivers (patched) (not using Xvmc, that seems to make myth very unstable and the osd loses all color). Also, I had a lot more problems with this motherboard when I first built the machine, the original bios was completely useless.. failing to boot half the time the latest bios seems solid though. I'm a linux noobie.. it's been a steep learning curve but I'm getting there!
