This function returns whether the current sound system is the legacy or the normal one. The return value can be one of the following two constants:
|audio_old_system||the legacy sound system is in use|
|audio_new_system||the normal sound system is in use|
This function is important only if you are using the HTML5 target module, as some browsers are not compatible with the new audio system, and so GameMaker: Studio will automatically switch back to the legacy audio.
if audio_system() == audio_old_system
global.SS = false;
global.SS = true;
The above code checks to see if the sound system being used is the legacy or the new one, and sets a global variable accordingly.
