Delayed audio problem

Quote from Crotach

Does syncing refresh rates cause audio delays?

It does for me, i have both "Adjust display refresh rate" and "Sync playback to display" turned off like that i have no delay problem.

I used to have "Adjust display refresh rate" to "on start/stop", but my gf and i are watching a lot of 3D movies recently and i have an addon to automatically switch to 3D mode on my TV when a 3D file is played.
Having "Adjust display refresh rate" to "on start/stop" would create a lot of problems, like not switching the TV to 3D or not putting back to 2D when the movie stop or having the screensaver in 24hz.
I have "Adjust display refresh rate" to "OFF" for a while now and i have not seen stuttering yet.

Kodi still has a default audio delay in its internal advancedsettings, you can either undo that in your own advancedsettings.xml file, or use Kodi's video OSD option, and select the audio offset in the Audio & Subtitle settings window, and then save that new setting as default for all videos.

thank you! this hint helped me to solve my audio delay problem! First I guessed that the audio passthrough is the problem as I did not have it with liveTV (it always gets transcoded to PCM). But the problem was the 24fps default internal delay of Kodi of about 200ms. I added this advancedsettings.xml to user config folders and reboot. DTS and AC§ are in sync now

<?xml version="1.0" encoding="UTF-8" ?>
<advancedsettings>
  <video>
    <latency>
      <delay>0</delay>
      <refresh>
        <min>23</min>
        <max>24</max>
        <delay>-200</delay>
      </refresh>
    </latency>
  </video>
</advancedsettings>

Thanks, it relay helped. I double checked your information and indeed, the default delay in the advancedsettings.xml is 175.

But if you want to override the settings, you do not have to reverse it, you need to set it to 0.

Fore me the following code worked just fine:

<?xml version="1.0" encoding="UTF-8" ?>
<advancedsettings>
  <video>
    <latency>
      <delay>0</delay>
      <refresh>
        <min>23</min>
        <max>24</max>
        <delay>0</delay>
      </refresh>
    </latency>
  </video>
</advancedsettings>

I think delay configured by default is only relevant if your TV can't play 24p nativly.

Hawk. That really made my day. I have a libreelec installed on my mac mini (late 2014) which is hooked via hdmi cable to the AVR Yamaha RX-A1050 and then to the TV (Samsung 46f8000). To gain shutterfree playback I need to set player option to adjust refresh rate (always), but then the problems with audio just began. I did almost everything; played with different settings, factory reset. Adjusting audio offset did work somehow, but I was never 100% pleased with playback until I created advancedsettings.xml settings listed above.

For me, with Pioneer VSX-930 + Panasonic TV (fully supporting 23.987, 24 etc.), the value -200 works: this is mandatory delay, when is AVR in turn off state, and works just like HDMI passthrough to the TV. Interestingly, when is AVR turned ON, the delay seems to be gone (even when AVR auto delay is OFF), so I just have setuped +200 delay on AVR.

Thank you very much for this thread, until now I need to setup audio delay for all videos within Kodi Audio OSD - and that way I cannot choose different values for different fps.
