I'm not sure, but I will check it out. If PLEX will work (which I haven't tested yet) then Foobar should too, provided it's a DLNA server. My general impression is that people aren't crazy about the HEOS app, finding it too clunky and with limited features. I don't mind it (at least not yet, I've only been using it a few weeks), but I'm old school. I hear wonderful things about Roon. Someday down the road I may try that with some Raspberry Pi dealio.
