Need help to stream sound from android to pc Over Wifi(similar to bluetooth).

My audio system(speaker,with no wireless connection ) is connected to my PC via aux cable,and i want play music from my android to it wireless. So I want know is there any way to stream sounds from my android to PC over WiFi(like Bluetooth).
There are many ways to do the reverse( that is from PC to android).But i want sounds from android to PC over WiFi not Bluetooth(as range is too low).
