I have an sb3 and a duet and yes that’s pretty much what happens they just become an output. I think volume might work, but as I have migrated to rpi units with iqaudio boards those sb units are shelved. Pretty old tech
based on the next post I guess I didn’t really play about enough…my SB3 died and the controller for my duet has battery issues…
I’ve been running Roon with various Squeeze flavoured endpoints since they’ve been supported, including a three duets, a boom and a SB3. The remotes still work for basic functions (pretty much all you’ll need), and I was pleasantly surprised that the duet controller even still shows the artwork of the currently playing track. All my primary control of the endpoints tends to be via the Roon iPhone app, but I still keep the Squeeze remotes handy to pause, skip tracks etc. Give it a go, you won’t be disappointed!
While basic control like play, pause/stop, skip forward/previous seem to work, volume doesn’t work as I hoped it would.
It would be nice if volume control could be supported on Squeezebox devices…
