fix: No-op on single player setAudioContext in desktop platforms

[livtanong]

Description

Calling setAudioContext on the windows platform throws a NotImplemented error. setAudioContext is handled as a no-op in the global method call, but not in a method call for a single audio player. This PR simply adds that no-op (and log message) for a single audio player.

Hi @Gustl22 , I'm not familiar with c++, so I'm just doing my best pattern matching as a human. 😅 Please advise me if this was the incorrect way to log the message.

Very cool, thank you. I try to add some tests and then we can be sure it works.
