Pi4 Build in audio output

[anon1796887]

Here is discussion and also solution how to use RPI output with Dietpi&Roon
(not RoopieXL solution)

Raspberry Pi 1/8" headphone end-point?

Which end-point software supports the built-in 1/8 headphone jack on the Raspberry Pi? This may be sacrilege, but I’m trying to find RAAT-compatible software on the Raspberry Pi that will output a simple 44.1Khz/16bit output on the built-in 1/8" audio jack. This is for a “Lo-Fi” application. Separately, I have a HiFi-Berry with a Digi+ board, but I’d like to set up an endpoint with an even cheaper hardware setup that doesn’t require the higher fidelity.

Chris_Lewicki has done good work to found out how to enable that headphone out with RoonBridge

I had an extra RPI4 and tested to install according Chris instructions (below) and it works perfectly

After setting up DietPi, the brief steps were:
apt-get update
apt-get install ffmpeg
apt-get install libasound2
