After you replaced the ogg, did you try Shift-restart?
Yes. But that doesn't change a thing.
Hmm. There are OXP/OXZs which are replacing the main theme or docking music. Please try without any AddOn and let us know.
I installed RandomDockingMusic.oxp and without removing the addons it worked right away.
So... Thank you very much for the hint.
One other thing, though...
Because my test sound file is rather short I thought i could set it to repeat.
So I changed
and because that didn't work I tried
It didn't work as intended (start playing the ogg sound again if it ends before the docking sequence is finished).
I read some documentation and it says:
function [b]playMusic[/b](soundFile : String [, loop: Boolean])
Play the specified music file, optionally looped. This may have no effect depending on the player’s music settings.
I wonder where those settings are...
