Hi guys.
I’ve been fumbling quite a couple of days to make it work.
I installed Balena Sound on a Raspberry PI 4 and it is connected to my hifi. I could not see the Balena renderer from my Android phone using Neutron Player connected on the same wifi.
I saw on some thread someone had some similar issue and he found this workaround: you’ll need to write a more recent version of Debian in a file.
In the repo files, go to the folder “.plugins/upnp”; open the file Dockerfile.template and replace, in the first line:
“FROM balenalib/%%BALENA_MACHINE_NAME%%-debian:buster”
with
“FROM balenalib/%%BALENA_MACHINE_NAME%%-debian:bookworm”
Push, update and restart and if you’ll have my same luck the UPNP will appear in the controller
