    Actually I can rerpoduce the issue, forcing bias 0.5 causes it to appear (not anything TsReader related as it happens with BDReader as well). Last time when I tested I had some logging commented out for other tests :whistle:

    Hello!
    I tested this with 15mins LiveTV and it is working great. No visible dropped frame and also no dropped frames in render stats (Shift+1). No A/V sync problems and no click sounds. Perfect experience! :)

    If I disable HWbasedRefClock, it seems that audio is in front of video. Logs are attached. Soundcard is a Xonar Essence ST/H6 with analog connected speakers.

    If I enable it, it is the other way round. Will attach logs in next post.


    regards, Winnie[DOUBLEPOST=1362574759][/DOUBLEPOST]Here are the logs with HWbasedRefClock enabled. Everything is tested with LiveTV ...[DOUBLEPOST=1362574888][/DOUBLEPOST]OK, somehow my two posts got merged to one. Hope, you can still see which logs belong to which setting ...

    From logs A/V sync is quite hard to debug (almost impossible at least for me). Some extra questions:

    1. How much the A/V sync is off in both cases?
    2. Does the issue happen with other audio HW than Xonar?
    3. Does the issue happen with Arcsoft Audio decoder DLL removed from LAV's install folder?
    4. Does the issue happen with all video files or with some specific videos only? (there is audio stream discontinuity without a stream change in the logs so the video might already contain something funky)
    5. Are GetMatchingSampleForTime related errors happening with all video files?

    1. It's less than 1 sec, but still very noticeable (lipsync)
    2. Will try with AMD-HDMI ...
    3. I'm not using LAV-Filters. I use Arcsoft filters directly.
    4. I just tested with LiveTV.
    5. ???

    regards, Winnie

    So it is off a huge amount, not something like 50 ms which would be hard to spot.

    Could you try the MS audio decoder that ships with the OS? I haven't ever tested MPAR with Arcsoft filters directly so who knows if they expose some bug or are not compatible with live tv at all.

    Please test with some other videos as well.

    audiorenderer.log contains GetMatchingSampleForTime related errors, but we aren't sure if this is related.

    This is now with MS-Decoders. Video seems to be late now. Funny.[DOUBLEPOST=1362589034][/DOUBLEPOST]This is now with AS-Decoders again but also with AS AudioRenderer. Everything is perfectly synced ...

    Can these GetMatchingSampleForTime-Errors be responsible for small Hickups in the Video (but no framedrops!)?[DOUBLEPOST=1362589201][/DOUBLEPOST]SH#T!!! posts merged again. Hope, you can differentiate. "ArcSoft-Logs" were written later ...
