Button press plays audio on all platforms,except Android!!!

I tried with various codecs, on button click and trigger event methods and even using script with IEnumerator.
I simply need to call a sound , it plays on all platforms, except Android! The same sound play nicely when set On Awake, just like other music files I have lodaing on the scene.
Anyone have a straight answer, something that is supposed to work?
As I can uunderstand this is a major Unity problem for years!
I am testing on Bluestacks and a Samsung J5(5.1.1 stock)
Thank you in advance!

 

Nvm, it just worked.... my fault.
