To implement this, the audio data from the Pi is being replaced by the audio data from the TOSLink input. This requires the Pi to deliver audio data to the DSP. If there is no playback on the Pi, the DAC and amplifier on the Amp100 won’t work.\u003c\/p\u003e\n\u003cp\u003eHiFiberry has created a small program that outputs a dummy data stream on the Pi.
