TTS on remote RaspberryPi?

I have OH2 running nicely on a Raspberry Pi 3 locked away in a cupboard. I’d like to try TTS however want the speaker output in another room. Is it possible to set up a spare Raspberry Pi 2 to deliver the audio? I know there is Audio Sink features in OH2 but unsure what to install on the RP2 “client”. Suggestions?

There’s the Squeezebox binding (OH1, OH2), there’s also android clients for squeeze servers…
