Support play audio from internet url

[Wiggly8193]

Fixes #324

[ujas-m-simformsolutions]

@Wiggly8193 First of all thanks for creating the PR. I'm not sure but does directly setting audio url actually works? If yes then rather just adding a boolean for local files we would like to have a base abstract class and this will be implemented by all different types of method from which user can also provide path so that we can manage urls efficiently. So this will be overriding the current implementation.
