Feature request: audio played also if window closed #3217

Would be nice if the audio sent from a contact can be played also closing Unigram to the system try icon.
In Telegram you can play the audio then close the Telegram Window, the audio still be played.

1. Open a chat with an audio and play it
2. Close the Unigram Window to go on the try icon

Result: audio stop.

Expected result: Audio still play

Also because if the window is closed and audio stopped you cannot resume from where the audio has been stopped, you need restart all the audio from the beginning.
