How to load sounds based on selected value?

I want to load some audio files based on user selected environment. Let say env1.

I want all audios for env1 to be loaded into the project. I have many different environments, something like 25. If i load all of them, there will be lots of audio files which are not used for that environment.

what is the solution?

Music is loaded as you play it. For the sound effects you can disable the 'preload sounds' project property so they are not all loaded at the start of the game, then you can use the preload action to load the audio content you want. Later you can also unload it if for example you switch to that different environment and you no longer need that audio.
