Music Player container

I currently have a Raspberry Pi (with DAC) in my room attached to an amp and speakers, with Moode Audio installed on it, and it's perfect, been using it for many years. I can use plenty of MPD clients, or go through the web gui, and the sound outputs from the Pi itself.

I have similar hardware downstairs, except instead of a Pi, I have an x86 Dell thin client, with various Docker containers running on it. I'd like something that does the same job as Moode Audio (which is unfortunately ARM only), and outputs the sound directly from the host.

I've set up a Jellyfin container, and it's a great bit of software (will keep it for TV and movies), but doesn't allow me to output sound from the Dell PC itself. Is there a plugin or some other config that would let me do this? I'm aware that Airsonic would probably work (installed it, but not full tested it yet), but I much prefer the look and feel of Moode and Jellyfin, especially as it's not just for my use.

Does anyone have a similar set up?

Thanks

[edit: I can install Mopidy-Jellyfin, and cast to that. It works within the Jellyfin gui, and outputs from host. Would prefer something in a container (had to install directly on the Linux server) and I'm still looking, but I have something that works.
