I’m getting interested in getting some sort of smart device, mostly to stream music. I like the idea of being able to tell a Google Home device or something like that to stream a particular online radio station (NPR, WLIR, whatever). I don’t have to be able to use my voice – I’m OK with pulling my phone out to tell it to start streaming.
I can do this with a $350 Sonos device plugged into my stereo. I can do it with, say, a $100-$200 smart device, standalone, although that will sound much worse than my stereo.
However, I have several laptops lying around, not getting much use. I would happily turn one into a full-time Smart Device, so that I could tell my phone to stream something through it. It would stay on and plugged into my stereo, just waiting for my phone to tell it what to do.
How can I accomplish this? Looking around online, it seems like Rhythmbox may be a possibility, in that it can be a UPNP client. Would it appear to my phone as a device that can be streamed to? Is there some other way?
