If I have something like a Pi or any other small Linux based box (I'm thinking mainly about the cheap Android PC sticks you can get for about £30 with just an HDMI output), would it generally be able to output unencrypted audio over HDMI so that I can break it out using a simple cable[1]?
I'm looking to play with multi-room audio on Linux and little boxes like these seem ideal if I can get audio out of them easily.
I can't think of a good reason why Linux will encrypt things by default (and none of my sources will have evil DRM on them) so this ought to work fine, didn't it?
