roon-cec-controller-extension v0.0.1

roon-cec-controller-extension

Roon CEC Controller Extension should allow you to control Roon Core (⏮, ⏪, ▶️, ⏯, ⏸, ⏹, ⏩, ⏭ ) from your audio amplifier remote control, having your amplifier connected to a Roon Bridge via HDMI using CEC protocol.

You should install this extension on a device connected to your HDMI amplifier, probably your Roon Bridge (although you may have the Roon Bridge and the Roon Core on the same computer).

NB: This extension is heavily inspired by roon-extension-powermate.

It relies on

• the Node Roon API
• hdmi-cec which relies on libcec

It should work with any device that supports libcec:

• Raspberry Pi
• Vero4K+
• Pulse-Eight USB-CEC Adapter
• Pulse-Eight Intel NUC CEC Adapter
• Some Exynos SoCs
• NXP TDA995x
• Odroid C2 (Amlogic S905)

This is a work in progress (but it works for me). Use at your own risks.

Todo:

• Add volume control from Roon Core to the amplifier.
• Display music titles on Amplifier
• Power on amplifier / switch source automatically

Install Node

Installing Node.js via package manager

wget -qO- https://deb.nodesource.com/setup_8.x | sudo -E bash -
sudo apt-get install -y nodejs

Install cec-utils and libcec (if not already installed)

sudo apt-get install cec-utils

Testing cec-utils:

echo 'SUBSYSTEM=="vchiq",GROUP="video",MODE="0660"' > /etc/udev/rules.d/10-vchiq-permissions.rules
usermod -a -G video YourUnprivilegedUser

Log off, log back in.

echo "scan" | cec-client -s -d 1

Install and run roon-cec-controller-extension

git clone https://github.com/benjaminbellamy/roon-cec-controller-extension.git

Et voilà !
