2 years ago Can you share the code snippet you used too?
Can you try with this answer from stackoverflow https://stackoverflow.com/questions/45444010/alsa-issues-on-raspberry-pi
Such configurations can be difficult for new comers in raspberry pi. Will work on a docker image for raspberry pi to have quicly reporducible results
