A good example is LibeELEC generic advancedsettings file (which is not used for Amlogic projects!):
LibreELEC.tv/advancedsettings.xml at libreelec-7.0 · LibreELEC/LibreELEC.tv · GitHub
So even though i see this being loaded in the log file
[code=php]
NOTICE: Contents of special://xbmc/system/advancedsettings.xml are...
<?xml version="1.0" encoding="UTF-8" ?>
<advancedsettings>
<showexitbutton>false</showexitbutton>
<cputempcommand>cputemp</cputempcommand>
<gputempcommand>gputemp</gputempcommand>
<video>
<latency>
<delay>0</delay>
<refresh>
<min>23</min>
<max>24</max>
<delay>175</delay>
</refresh>
</latency>
<busydialogdelayms>750</busydialogdelayms>
</video>
<samba>
<clienttimeout>30</clienttimeout>
</samba>
</advancedsettings>
[/php]
It doesn't actually do anything?
EDIT: Ok after assuming that the above was working and was the reason for my audio issue for a while now, i add this to my own advancedsettings.xml
[code=php]
<video>
<latency>
<delay>0</delay>
<refresh>
<min>23</min>
<max>24</max>
<delay>0</delay>
</refresh>
</latency>
</video>
[/php]
And suddenly no more audio issues, so the default advancedsettings.xml in /usr/share/kodi/system was causing the problem lol
EDIT again: also the "<busydialogdelayms>" in that default advancedsettings.xml was removed in v12 Frodo advancedsettings.xml - Official Kodi Wiki
