How to transfer audio stream from computer to smartphone?

Question

Audio

The house has a computer (laptop) where movies are watched and music is listened to.
And on the other side of the room is a decent audio system.

Q: How do I get audio from my computer to that system without running audio wires across the room?

I thought that there might be a way to transfer the audio stream from a computer to a smartphone (Android) via WIFI, and then plug Android's audio output into the Line-in of the audio system.
I just can't find software for this.

Answer 1

SlavikF , if you want a "full" stream, then either SoundWire or Airfoil + AirBubble .
These are just paid options.

Answer 3

A decent audio system and Android's audio output is not the best combination.

Answer 4

Neither Audiogalaxy nor AirPlay allow you to send an audio stream from your computer. They only can send audio/video files to the phone.
The task is to send the audio stream. For example, if I go to youtube and watch from there, or open my player on the computer, that is, any sounds from the computer should be streamed to the phone.

Answer 5

Here and here they made radio headphones from an FM transmitter. Well, unless of course you are not embarrassed that your neighbors can listen to your music.
