Fresh Rune Audio user here.
Set it up on my RPi with a TX100-transmitter from Audio Pro as USB soundcard and it worked like a charm!
To the point: I'm looking for alternatives for Squeezebox and there's especially one feature that is missing, and I don't just mean in Rune Audio. I've looked at a lot of systems (Sonos, BlueSound, Raumfeld to name a few) but NONE of them feature any sort of jukebox. It's starting to get really frustrating. It seems these systems aren't designed for listening to music but rather albums.
I know you are just looking at incorporating proper browsing of tagged files so this would of course have to be in place first and foremost. But after that, do you have any plans on looking at something "jukeboxy"?
For example, the way I use it today on the Squeezebox:
Select random play -> Pick genres -> Play songs randomly.
This coupled with auto play is really nice, rarely need to do anything but turn the system on to get some background music going. Thoughts? Is this perhaps already built into MPD in some way or is it more a matter of the client creating playlists on the fly in the background?
