Audio delay ~200ms when "Adjust display refreshrate"

Hi!

I'm on LibreELEC Generic 8.2.5

I run my Kodi gui in 1080p@60 for a smoother experience. I am also having "Adjust display refreshrate" set to start/stop because the video stutters if not set properly.

Recently I swapped my Odroid C2 for a Intel Nuc6cayh and I suddenly noticed that when Kodi sets the TV to 24p, my audio wont stay in sync.

So for liveTV running at usually 50hz it's fine, but for a movie in 24p it's out of sync. (Which makes saving a global audio offset just as bad as having to set it everytime I start a movie)

I do experience that the audio delay is worse when watching DTS content, I guess that might be because I use DTS transcoding since my Sonos playbar only handles Dolby digital.

Is this something that can be solved or will I have to accept the fact that I need to constantly adjust the Audio offset?

You can add some adjustments in the advancedsettings.xml file, see the video section.

Example:

Code

<refresh>
  <min>23</min>
  <max>24</max>
  <delay>125</delay>
</refresh>

Will that only affect 24p video? Because I wont need the settings for ex. liveTV or youtube

And weirdly audio passthrough stops working when i have the delay settings present in advancedsettings

Nvm. Typo in advancedsettings caused the failure of passthrough. It's working now! Big thinks!
