Yes, we support synchronized playback for Squeezebox devices.
The next major release is slated to include RoonSpeakers support, and will expand multi-zone capability. Once that’s out, you’ll be able to link:
- Airplay endpoints with other Airplay endpoints
- Meridian endpoints with other Meridian endpoints
- Squeezebox endpoints with other Squeezebox endpoints
- RAAT endpoints, RoonSpeakers endpoints, and local/USB audio devices amongst themselves.
The “first class” solution going forward is RAAT/RoonSpeakers. Once that’s in place, the zone linking product will feel a lot more complete.
No-one on earth (that we are aware of) currently attempts to synchronize playback across technologies. It would be a huge challenge, but really, really neat. We haven’t scheduled any work for that project, but it remains on the list of things I’d like to see Roon do someday.
