Hello,
I am trying to use the 4mic array v2.0 with a raspberry pi 3b+.
The mic has been factory reset using : python dfu.py --revertfactory.
Our raspberry is connected to the mic through usb and use it as default output. Our speaker is then connected through jack to the mic.
The speaker is playing sound (so the mic receives sound) but the merged playback channel is always empty.
Pactl info :

We tested the same microphone on a computer with the same pactl info output and it works.
Do you have any idea why it does not on the raspberry pi ?
Thanks in advance,
