I have installed Docker on my OpenWRT (RPi4 4gb), it works great, however I'm trying to get the following app to work. : https://github.com/dubo-dubon-duponey/docker-shairport-sync
I have installed kmod-sound-core and kmod-sound-arm-bcm2835 along with alsa-lib,alsa-utils ,alsa-utils-test, and I simply cannot get it to broadcast a signal.
I have tested it on a spare RPi4 and it broadcasts on buster.
I'm 99.9% sure I'm missing a key element to this but not sure what.
I tried tcpdump but it doesn't look like it's broadcasting anything on port5353, while on Buster it does.
Any help would be greatly appreciated.
