Redirect the application sound to Matrix audio jack

[pilakedh]

Hi ,
I would like to use the AVS demo with the audio output directly from the Matrix voice device 3.5,, jack instead of that from Raspberry pi. Additionally I would like to access the same audio output buffer to use it as reference signal for echo cancellation algorithm inside . Could you please give me some directions in this area?

I also want to use this function. Any time window when this is available?

This question is ignored for a long time, also on the Matrix forum, so I would not hold my breath
