Yep I have that test sample to. But it's in Dolby 2.0 I think. I will pm you later for the uploads.

@meridius interesting. could you please do another test: remove the AVR and connect the Kodi box directly to the TV set.

Hi there

Just did that test and it seems the amp is introducing about a -20ms to a -30ms delay when hdmi is hooked straight to the tv and bypassing the amp

HDMI = PC to Amp to TV (hardware acceleration On ) -180ms
HDMI = PC to Amp to TV (hardware acceleration Off ) -50ms

HDMI = PC to TV (hardware acceleration On ) -150ms to -160ms
HDMI = PC to TV (hardware acceleration Off ) -20ms to -30ms

the audio is still out of sync with or without the amp but at least this test showed me I have a -30ms to -20ms delay with my amp.

what next ?

[FernetMenta]

Interesting. Considering all this information I would guess that your AMD systems suffers from the issue and the Intel system does not. Could you confirm/bust this assumption by the following test.

- disable passthrough and set number of channels to 2
- remove the Amp from the chain
- test intel and amd with and without hw acceleration

[meridius]

hi mate sorry for not getting back to you but will try and get this tested soon been a busy weekend and have to do the test next weekend as I had a load of xmas shopping to do this weekend

[FernetMenta]

thanks for the update. I stay tuned here.

[Rouzax]

I have the same issue with Intel. When I sync TV display rate to source I have to set a delay of 200 ms for it to be in sync. When I disable sync display refresh rate it is 60 Hz and 24p material plays without delay.
This is my setup with Windows 8.1:

please don't spam this thread with useless info. nobody here is interested in the type of your memory or SSD.

[DerekCuster]

Pretty sure if he didn't post his specs he would have got an almost carbon copy of that post but complaining he hadn't provided enough info lmao

[Piers]

I'm certainly noticing this on v14.0 RC2, not 175ms but near enough.

[brimnac]

Yes, when the screen resolution / GUI is at 24 Hz and the video is as well, the delay is still there, for those who asked. I tested this tonight, and it's too late to get any debug logs. My apologies in advance, I wanted too help with what I could. Openelec didn't have this, just Windows.

[meridius]

Hi there brimnac we already know this as I posted that about a week ago. I will get back onto this on the weekend as I will have alot more time this weekend to do some more testing as requested.

Unless things have changed - Openelec has a delay of -175ms preinstalled on their builds (hence why there is no delay).

Thank you for that constructive feedback.
Just wanted to be sure my CPU was listed as this is responsible for the decoding.
