We have just moved into a house that has wired outdoor speakers only. The cables come out of the wall and into in our lounge. I am wondering if there is a device that will connect to those speakers so I can play my songs from my pc wirelessly. Or any other suggestions would be appreciated. My aim is to play songs from my windows media player on my pc (that i have synced many many years of songs to) through my outdoor speakers. Maybe something bluetooth that I can swap and play songs from my phone through the speakers also. Please help. Prefer not to have to get a av receiver. Thanks
