I'm needing help to configure pulse audio to read from the mic array on the Matrix Creator One,
The following are the lists of devices, what creates the devices in /tmp here is the source that does it https://github.com/matrix-io/matrix-creator-malos/blob/1a09b776c5c762093a42b286457f06823ec46d78/src/driver_micarray_alsa.cpp [1] Essentially I can't get the mic_channel0-8 to input into Pulse Audio. Input 8 is a combined microphone input with beam forming done on the FPGA chip.
