Audio

The volume of the TV can be adjusted using the Keypad. It will trigger an automation that will change the volume using CEC. This part is mostly for my kids.

I use mostly my headphones.

The Sound Blaster Recon 3D is used connect the TV to the Douk Audio Mixer MX3 (2-CH) using an optic cable.

The audio mixer is used to mix the audio from the secondary Chromecast with the audio of the TV. I can also adjust their respective volumes.

These two devices are powered on automatically by a Smart Plug when the TV is powered on by any of the automations.
