I'm not entirely sure if this feature exists but I want to ask.
I've got my RPi 3 with runeaudio on it + connected USB HDD & Speakers. I want to ask if it's possible to use my RPi as a sound reciever from other devices f.g. phone or computer with windows on board through WiFi. Can I configure runeaudio on my RPi in that way? For example let's say I'm working on my laptop and somebody sent me music video from youtube. I open the link and I can hear music on both my laptop and rapsberry pi at the same time. Is even something like that possible? I suppose it has something with UPnP / DLNA, but I'm new into this and have no idea how to use it yet. Any help would be highly appreciated.
