From the project

Modular, Open-Source, Audio (maybe Video later) Receiver

I'm building a modular open-source AV receiver platform, with the following features - Receive digital audio from TV via HDMI ARC - Share control signals via HDMI CEC - Multi-channel audio decoding and amplification - Multiple outputs - Apply DSP effects

Use-cases: - Allow your TV remote to seamlessly control an existing analog amplifier/receiver - Send a mono mixdown from your home cinema to the bathroom - Room/speaker compensation - Start with a 2.0 system, later upgrade to 5.1
