Satellite doesn't talk to me :-/

[tsx-5]

Here's hoping this is a simple question, that I'm just being daft on... Following the tutorial I've put together a wyoming satellite. The led's light up when I speak to it, I can see in the debug window its hearing me speak, and it executes some commands - however, I can't hear it speak back. I've installed pulseaudio (as I do plan to play music through it) and have it bluetooth'd to a bluetooth speaker. I can play sounds that do play on the speaker (using aplay). Any suggestions on where I should be looking to fix this?
