Hello,
Im trying to bring my speech control application over to the Rock Pi S. But I do not want to use the built in audio hardware, because Im using the Respeaker Micarray v2 (want to use the built in algorithms for beamforming etc. instead of build those from scratch).
The problem is, that the Micarray is detected (ca see it with lsusb), but not visible to alsa (arecord -L does not show them (only loopback and rockchip)). So I think, ALSA is not configured to use usb audio devices… but my linux skills are to poor to change that 
Can anybody help me?
Thanks alot
Carl
