Help! Babelpod runs but no sound. Stops after selection of AirPlay speaker

[snibles]

Hey everyone!
I really need help to make babelpod to work. I already tried and tried again with no success.
Can someone help me, please?

I followed these steps:

A clean install of latest version of Raspberry OS. (Raspbian GNU/Linux 11 (bullseye))

sudo apt update && sudo apt upgrade -y
wget https://nodejs.org/dist/v9.8.0/node-v9.8.0-linux-armv6l.tar.xz
sudo mkdir /usr/local/lib/nodejs
sudo tar -xJvf node-v9.8.0-linux-armv6l.tar.xz -C /usr/local/lib/nodejs
sudo mv /usr/local/lib/nodejs/node-v9.8.0-linux-armv6l/ /usr/local/lib/nodejs/node-v9.8.0
nano ~/.profile,

then I added the lines:
# Nodejs
export NODEJS_HOME=/usr/local/lib/nodejs/node-v9.8.0
export PATH=$NODEJS_HOME/bin:$PATH

source ~/.profile

Installed an old version of Python:
sudo apt install python2
npm config set python "/usr/bin/python2.7"

then I used @maexdaemaege repo:
git clone https://github.com/maexdaemaege/node_airtunes2
cd node_airtunes2
npm install
cd ..

I also used @maexdaemaege repo for Babelpod:
git clone https://github.com/maexdaemaege/babelpod.git
cd babelpod
npm install
node index.js

Following these steps, Babelpod runs, and I can select the input/output on the web browser.
It evens recognize my USB sound car.
But as soon as I select the AirPlay speaker, it stops.

This is my terminal output:

@afaden @maexdaemaege is this project dead and current version doesn't work anymore?
This is such a cool project and I can't get it to work. Frustrating.
