[QUOTE="4Fred, post: 1091032, member: 16968"] Okay here goes... I have A/V sync somewhat off when playing some HD videofiles. Everything is fine when playing SD files or watching live-tv, sd or hd. Sound is a bit after the picture, lice half a second or maybe a bit more. It's not much but annoying. There are settings for audio delay at many places, my amp and in MPAR and so on, but I need the opposite.. what to do? Here is the longer story of things I already have tested how things are connected and configured. I have two Nucs, one in Bedroom and one in Living room. It was time to upgrade to Win8.1 and upgrade MePo so I did that, full wipe and clean install. no additional codec packs and stuff, clean system. I reinstalled the first client when it was in the bedroom, simple setup and directly attached to the tv using hdmi. Everything was just fine and all movies and videos played as they should. Codecs are configured according to the 5 min "perfect playback guide" and the only diversion from this is hardware acceleration is set to DXVA (Native) and not Intel Quicksync as the guide suggest. The reason for that is online videos problem with SVT Play. Switching back to Intel quicksync does not change anything exept breaking playback of SVT Play. So anyway, everything was fine and all tested a-ok so my thinking was to move this from the bedroom to the livingroom and that's what I did, things where still fine until I wanted to watch an epoisode of GOT, a/v sync off. Oh yeah, my amp does handle dolby digital and dts and blah blah so I ticked those boxes and figured things now would be in sync, but no, still off. So, as soon as connecting the computer directly to the tv using hdmi a/v sync is fine, and as soon as connecting it MePo --> amp --> tv a/v sync is off. First I tested different codec settings and audio renderers and no matter what I did i could not make it any better, playing with audio delay only made it worse. The tv also have some settings for a/v sync but these make no difference at all since audio never ends up in the tv. The amp have a/v sync and it can also only delay audio. I reset the tv to factory defaults, no difference. I reset the amp to factory defaults, no difference. Logs are attached and what I did are exactly this: Reboot PC so things are "fresh". (skipping forward in the logs is me searching for speaking scenes to make shure things are as I claim) AMP Says part is me pressing a button on the amp and it display what type of input is coming to the amp. Start live-tv SVT1 (in sync) AMP says: MCH 5.1, fs 48 kHz, 1080p/50 Switch to SVT1HD (in sync) AMP says: MCH 5.1, fs 48 kHz, 1080p/50 Start Fargo S01E01 (in sync) AMP says: PCM 2.0, fs 48 kHz, 1080p/24 Start GOT S01E01 (out of sync) AMP says: Dolby D 5.1, fs 48 kHz, 1080p/24 Start The Hobbit The Desolation Of Smaug (out of sync) AMP says: DTS 5.1, fs 48 kHz, 1080p/24 Start Arrested Development S01E01 (in sync) AMP says: PCM 2.0, fs 48 kHz, 1080p/24 If rating the different in or out of sync I would say "The Hobbit The Desolation Of Smaug" is the most out of sync of them all. Hardware used:"Livingroom Client" NUC model is Intel DC3217IYE Amp is Teac AG-D500 TV is LG55LM620T Connection is NUC --> AMP --> TV [ATTACH=full]152643[/ATTACH] [ATTACH=full]152644[/ATTACH] [ATTACH=full]152646[/ATTACH] [ATTACH=full]152647[/ATTACH] [/QUOTE]
