The game may not have sound, but it's completed.

My first ever game development project: not the best at all... 

some struggles were stronger than my begginer game dev capabilities could handle, but it's a playable 2D game!

The Struggle:  sound wouldn't play on the WebGL build (but would works fine in the Unity editor)

I went after a way to fix this...

• The import settings of the audio files?  

i even checked the  "Override for WebGL" option (likely a dumb idea) but nothing was solved :/

• My AudioSources had an audio clip but didn't have an Output (which required an Audio Mixer). 

took care of that and... nothing happened either :/

• The Audio Listener attatched to my Main Camera?

it was active... All good with that.

• The Audio Mixer i created as the Output in the Audio Sources?

yup. i am not even sure if that was really necessary but all good with that.

• The audio settings of the project?

they  were just fine as well.

• The 'Play on Awake' option on the AudioSources?

enabled or unenabled... both scenerios didn't make a difference into it playing :/

• The 'Audio Mixer Suspend' option on the Audio Mixer (in the inspector)?

i unckeck it and the Audio Listener (in the Audio Mixer) became active but..... no sound?!!!!! aaaaaaaa

I WAS  EXTREMELY CONFUSED!

buuuuut... i rather have a completed and published (awful and imperfect) project than a perfect one that never sees the light of day :)

So, here you have it. Pretend it is a simulation of how it would feel like to be hearing impaired.

If you'd play the game as it is, i would be thankful to you... 

Maybe, if you don't actually have some hearing impairement, have some nice music playing in another tab.

Have a nice day, as far as it is possible for you :)
