Multi room capabilities with Snapcast

Postby Mr. Mister » 01 Jun 2016, 00:40

I have added multi room capabilities to RuneAudio including Snapcast for timesynced streaming to multiple players inside a zone.
Have a look:

Create zone (player becomes a zonemaster) or add player/room to existing zone (player becomes a zoneslave)

Sorry for the next post, but I may add just 3 pictures.

Hi Mr. Mister,

welcome to RuneAudio.
Nice work you have done.

Let me know if you (RuneAudio Team) are interested on the source code.

Yes, we are interested in the source code.
Best option would be to make a pull request on Github (dev tree).

Hi Mr. Mister, good job. We are absolutely interested in such solution as it's already in our roadmap. Are you working on a fork of the RuneUI repo? I'd like to test your implementation and see how it could be integrated in our new system (the frontend and the backend have been rewrote almost from scratch).

Hi Frank, hi ACX

@Frank
You have a PM.

@ACX
Nice to hear :-) I'm not working on a fork of the RuneUI Repo. But I hope Frank will explain what to do that I can make a pull request on Github.

Before proceeding with a pull request on the dev repo I'd like to test the implementation myself. Forking the RuneUI repo is required also to make a pull request, so I'd suggest to start from there.

Dear
Great job what you do! Now it is time for bild my own multi-room system. I never use PRi before. So I have no idea how to program in linux. But you do great job and put it for free for us.
Well now it is my time to support you. I plan do design board with 3. amplifier (for 3. room) Volume control can be done with MCP4651 digital potenciometer on I2C. It can be address up to 9 MCP4651 on same I2C. For Amplifier I'd like to use TPA3110.
I'm good in design PCB but not so much on audio so please let me know if you find some errors.

Developer please let me know witch pin can be use on RPi

When board will be done and work I'll publish full schematic, board and gerber files

attach: schematic for 1. board (when it will be conform that is OK I will add 2. more )

Why is there additional HW required?

I was hoping for a solution like this: install multiple Raspberry Pi's in different rooms with extra plug-in board (example the: hifiberry) to either add optical audio connection or the amplifier plug-in board version so you directly can connect speakers. Then on the different Raspberries have the Runeaudio software running and then you can make one or multiple zones out of it. Exactly what Mr.Mister is showing in this thread.

I possible and I can help I would like to test this beta feature. I already have multiple Raspberries already lined up in different rooms. Just PM me in case I can help.
