Problems:
1. I can't get a remote client such as "Retune" to connect to fork-daapd on OMV. I've got the standard plug-in fork-daapd working for a DAAP client on my network (Rythmbox). The remote client, "Retune", is definitely broadcasting to the server (can see it when I run "avahi-browse -r -k _touch-remote._tcp") but I can't connect to it using the "/usr/share/doc/forked-daapd/scripts/pairinghelper.sh" script. I've noticed the remote section is missing in the forked-daapd.conf config file.
2. The standard config isn't setup to connect to local server audio output, which is how I want to use the server plugged into my stereo. I would go through and set this up in forked-daapd.conf however at the top of "/etc/forked-daapd.conf" there is the statement "# This file is auto-generated by openmediavault.... # WARNING: Do not edit this file, your changes will get lost." There is no web admin interface for making any changes other than the basics of one directory to scan for music.
3. fork-daapd plug-in in OMV is version 26.4 which was released on 2 Oct 2018. There have been a lot of improvements from what I can tell, the current release version is 28.2. I realise this is a Debian problem, since Debian maintainers haven't updated this package, not OMV. I understand this is also a Debian problem of why there is no web interface to fork-daapd.
4. There is no information about the fork-daapd plug-in in any of the documentation for OMV, other than a statement that it exists.
Question: I am correct to assume the current plug-in version is really only for sharing music to DAAP clients across the network where other configuration isn't required? And, for what I want to do, using the server as the media player connected directly to my stereo and controlled by remote on my phone, I need to either compile and configure the later version or install the latest docker version of fork-daapd?
fork-daapd has been renamed to owntone-server for anyone interested.
