[ReSpeaker 2-Mics Pi HAT] Input and Output simultaneously


I’m creating a SIP client with the ReSpeaker (audio output), an USB microphone (audio input) and PulseAudio for AEC. This setup works - however, I would like to use the microphones on the ReSpeaker instead of the USB microphone.

Therefore my question:
Is it possible to use the ReSpeaker as an input and output device simultaneously?

Currently, when I point everything to the ReSpeaker I don’t get any audio.


@bortus , were you ever able to get this working?

Unfortunately not. I’m stuck with the USB mic solution for now.
