No sound with Pulseaudio on NAS with Iris

Q&A
1

I was looking for a web player for my music collection on my NAS and just found today Mopidy. I have the server version of Ubuntu 20.04.3 LTS running. I had no audio server running so I installed pulseaudio. I changed /etc/pulse/default.pa, added this line load-module module-native-protocol-tcp auth-ip-acl=127.0.0.1 and also changed the mopidy.conf according to the documentation. pulseaudio is running. I also tried restarting the whole system but I couldn’t get a sound out of Iris.
What could I have done wrong?

I thought my post got deleted. My problem is solved, I misunderstood Mopidy as I thought I could stream my music via a browser to all my devices. I’m using Plex now to accomplish this.
