Play phone's music wirelessly through computer's speakers

I realize this thread is a couple years old now, but in case anyone else comes across it:

With windows 8.1 (not sure about windows 8), you don't need anything extra to play audio from an Android phone (not sure about iPhone), just pair the phone with the computer and go to Bluetooth settings and select to connect to the PC (by name) then select whatever audio on the phone you want to play.

Any media played on the phone will play through the computers speakers. Phone calls will still be routed to the phone.

Alternatively, if you have an android phone (im unsure if it is available for iPhone), you can download an app called Bubble UPNP from the google play store. As long as your PC and phone are connected to wifi, and windows media player is open and set up on your pc, you can play music wirelessly to your PC from any where in the house.

To configure windows media player, if in windows 8+, click stream, and allow all of the options if you can. If you don't have windows 8 or above, then google how to do it. There are tutorials all over the internet for configuring windows media player for streaming. Then go onto the Bubble upnp app, click devices. Your PC should appear provided your phone and PC are connected to Wifi. Next go to Libraries to select the music you wish to play. Finally, go to the now playing tab, click settings, and click Renderer. Ensure your PC is selected. You can now play music to your PC, change song, and even adjust the volume of your PC from the app!

Hope this helps. Any further enquiries then just ask.
