Audio delay or video advance with Dolby digital
Dear AVS users. This is my first post, and I apologize if this is not the correct place for my question.
My setup is Samsung TV UE65NU6025 connected to Denon AVR-X2500H via HDMI using CEC/ARC. Control works fine.
My issue is as follows:
When I set the TV output to Dolby Digital, I have audio lag/delay. I see lips moving before the sound arrives. Or in other words, picture comes first, then the audio.
On the Denon AVR, delay is already set to 0, so theres no way to advance the audio further. On the TV there is a setting for Audio delay as well and this one is also set to 0 so no option to advance furthere. By the way, this setting applies for SPDIF only, so no use anyway with HDMI/CEC/ARC. I tried to disable the auto sync feature in the Denon but with same result.
1. When I set the TV output to Dolby Digital I have perfect surround sound but also distinctly audio lag/delay
2. When I set the TV output to PCM, I have little audio lag/delay, but not much. The problem with using PCM, is that I loose a lot of effects especially in the rear speakers and the audio is less punchy overall in comparison to Dolby Digital as output.
3. I tried to use SPDIF optical cable as the audio source instead of HDMI. Audio delay is still present but it is low in both PCM/Dolby Digital output mode from the TV. The problem with using SPDIF/optical cable is that I have to disable HDMI CEC and therefor no longer are able to cotrol the AVR with the TV remote.
Does anyone else experience this issue and if you have, what have you done to fix it? I would really appreciate any tips, tricks and test, any of you can recomend me to try?
I have read and searched for answers on this, but all I can find is about delaying the audio in situation where the audio arrives before the picture. My situation is the opposite. I see lips moving before the audio arrives. I see dors shut, before I hear the "slam". I see kingkong hit his chest, before I hear the boom ect.
Any feedback will be appreciated and again, sorry if I posted this the wrong place.
