I want to setup for my parents for them to be able to play mp3 music files that are on a non Bluetooth PC (motherboard: ASUS B85M-G R2.0) and have the sound come out of an old stereo (non Bluetooth, Sony FM Stereo/FM-AM Receiver STR-AV770) in another room on the same floor. They have a PC in the basement where the internet goes to and then the internet goes to a 2nd computer upstairs using Powerline. It is from the 2nd computer upstairs that I want to be able to select the songs to play on the stereo (I don't want for them to have to run up and down stairs to change the music being selected). I'm not sure what I need to do? I live in BC, Canada.
