[QUOTE="tourettes, post: 654809, member: 10858"] I cannot reproduce the lipsync issue with NVIDIA HDMI (cannot test with SPDIF since I cannot get picture to monitor with the HDMI in that case :)). Even 500 ms buffer give correct lipsync. Based on that I would say it is something in the Xonar's drivers (they have been already proven quite buggy :)) Also didn't you say that Reclock has lipsync issue as well? That would definitely point into the driver direction. I guess that could be the only solution with Xonar, lower the device buffer period as small as you want the maximun amount of possible lipsync to be - 10 ms could be a good choise since it is already two times more forgiving for the possible sample dropouts (CPU will be filling the buffer two times slower speed).
