Hello,

I'm planning to install a home automation system.
I've already started some testing, especially for the multi-room audio
function.

My current test config is :
- a RPI 3B running as server (Picoreplayer 3.50 with LMS activated),
- 2 RPI zero (one with Justboom Amp, the other with Hifiberry DAC, both
with Picoreplayer 3.50 and Squeezelite player activated).

All this is running fine.

My final config will integrate 10 players (10 RPI zero, with wired LAN),
and if possible the ability to stream analogue audio with 'low' latency
(typically 100 or 200 ms, mainly for TV audio).
For this I've purchased a ADC + DAC module, plugged it onto the RPI
server, and activated the Wavein plugin on this RPI.
With this the LMS server can stream analogue audio, but the latency is
high (about 3 seconds).

So I have 2 questions :
- has someone already tried a similar config : 10 RPI players + 1 RPI
server, all wired connected ?
- has someone tried to reduce the streaming latency, in the case of a
local ADC source ?

>From what I've seen on forums, LMS treats this ADC stream as a remote
(Internet) stream, and so uses a reception buffer of about 3 seconds of
data; which is probably oversized for a local stream.
Maybe there is a better way to stream an analogue audio source ?

Thanks for any information/suggestion.

Claude
