Streaming audio to speakers

Question

Arduino

Good afternoon!
There is an old Sony amp with decent speakers at home, a vinyl player is hooked up to it. I really want to be able to output sound to it when watching movies, when listening to music. Those. from a computer / phone via bluetooth or wifi, in extreme cases ethernet / miniusb / * cable for iphone / ipad. In other words, turn it into wireless speakers that you can pick up from any device.
Tell me how can I implement this?

Answer 1

shairport, xbmc with airplay enabled.
Linux users - pulseaudio over the network.
but in any case, there is nothing better than a direct connection with line out --> line in wires.

Answer 2

Well, I caught how to stream sound from IDEVICEs through raspberries, the question remains how to do the same with a PC, ideally it would be to emulate a playback device in Windows, i.e. now I will connect to the main PC via hdmi TV and small speakers, in the sound settings I can choose where to direct it, it would be convenient if the third option appeared there with output to raspberries.

Answer 3

In Raspberry, the sound quality is below average, unfortunately.
You have to screw on the outside.
