Multi speakers wireless in sync, Technology not there ?

[mariusco]

Hi,

Looking for a solution to keep in sync 10+ speakers (with volume control / speaker) playing music from one server / device,
which streams non-stop.

I've tried so far:

• mplayer with udp sync and source - get's out of sync in 10 seconds.
  https://www.joshcurry.co.uk/posts/synch ... eaudio-vlc did not work for me
  http://gqrx.dk/doc/streaming-audio-over-udp is as well out of sync with 2 clients
  https://github.com/hzeller/gmrender-resurrect could not get it to run
  http://www.pogo.org.uk/~mark/trx/ did not worked for me. I did some code changes to select right pcm device, nada, no sound.
  https://github.com/badaix/snapcast/blob ... r_setup.md decent, but the latency between speakers is annoying

I am open to any other options, other RF chips, FM modulators, as long can keep the speakers in sync. (with smart control over volume/speaker)

Thank you.

Have you looked at Logitech Media Server aka squeezeserver aka slimserver and its software client squeezelite?

That does sync over ipv4, ethernet or wifi.

forked-daapd and shairport-sync work for me.

Had it working and in sync with 4 sets of speakers.

forked-daapd is an itunes/airplay server
shairport-sync is the corresponding client.

Far as I know both are open source, and shairport-sync also works with other airplay sources.

The OP needs to clarify what he means by "in sync".

LMS is certainly able to have the same source playing on speakers in different rooms and the relative delays can be adjusted. But multiple speakers in the same room or large hall is a different ball game.
