I got annoyed by having to start pulseaudo-dlna always with the terminal.
Just use that file in ~/.config/argos/pulseaudo.5s.sh
and run chmod +x ~/.config/argos/pulseaudo.5s.sh
to make it executable.
Install argos, the better bitbar alternative from here: https://github.com/p-e-w/argos
You might need to install pulseaudio-dlna before that.
You can stream your audio to many devices, even if they don't support chromecast. I have a delay, but that doesn't matter with music. The script offers a start, stop and settings option and shows whether it's running or not.
