This does not work as expected.
load_prc_file_data("", "audio-library-name p3openal_audio");
I get a message:
this only works through the Config.prc file.
I can add a custom prc file, too, cannot specify an audio library. Only valid from folder etc.
The essence lies in the folder itself, if you place a user prc, then it will normally install the audio library.
