audio mux for H2/H3 - orange zero / one

Recommended Posts

Hi,

 

Trying to setup audio mux on orange pi boards, for now trying to stick on orange pi ZERO & ONE ( both of them ).

 

By mux, meaning will try to setup some peers which can play locally or stream sources they have.

Let's say all peers have

- x2 line in

- x1 mic

- x1 line out

 

Want to dynamically connect any source to any output on any peer.

For example after choosing, you can able to play line in of peer 1 on peer 1 output   OR   peer1 line in on peer 2 output

And I think CD quality is more than enough.

 

Trying to find any tools that will help to make this.

 

Two solution points needed:

- hardware:

        ?? as far as I can find, there is "line in" on ONE, maybe also in ZERO but how to connect them? ( can see on the chip specs but no luck on orange boards ?) Or is it more easy to     

        connect a usb sound card which have these inputs ? (actually line in is the problem , maybe muxing mic in or ... )

        By the way trying to hold the cost. Find some cheap usb sound tools , dont know if suitable or not. And ok if it needs to solder, for an optimum solution.

- software:

        Lots of choices available, if doable mpd seems to be fine ( not sure if dynamic enough ) or ffmpeg seems to be an easy one.

        Headless solutions will be good so all terminal tools without GUIs.

 

Can you share your ideas about this project ? Right direction to a path or any comments on a title will deepen the approach.
