Summary first - I'm looking for software to use for web-controlled music playback. Main requirement is playback via a DAC on the hosting device and a half-decent UI for it (though streaming would be nice...).

Hardware-wise, I've currently got a Pi Zero W paired with a HiFiBerry DAC+ Zero, which has been fine for me quality-wise, routed as an aux input to an old HiFi. That, plus plenty of space elsewhere to host split apps - currently running Emby as a main streaming host for other media, and the media is just on a NAS pulling over NFS.

I've been using Volumio for a while, but have been frustrated with a few things (UI, playlist management, etc) so I'm looking for a change. Streaming from Emby/Jellyfin via DLNA looks like it might be a decent fallback, but I'm wondering if there are any nicer ways to handle it.

Any ideas? Open to switching a few bits of infrastructure around, of course :)
