Had a similar good experience a while ago with a Fire TV. The remote can be configured to control my audio amplifier, although it's a rather obscure brand [0] and not even an AV receiver at that (it only does stereo audio, and has no HDMI or video inputs / pass-through). --- [0] They are, however, very open and publish the remote codes.
