Hi, I’m having a weird issue with the microphone array…
I have microphone set up correctly, following the Alexa tutorial & some issue threads on this forum (.asoundrc in place, defaults.ctl and defaults.pcm in alsa.conf pointing to snd_dummy) and microphone works and I can record sound with it successfully. However, it stops working after a while (maybe after 10-15min or so). “arecord -l” still lists the devices correctly, “cat /proc/asound/modules” still lists snd_dummy and I can even attempt to record sound with arecord, but the microphone is receiving no data. Rebooting the device seems to fix the issue, but only for a short while as the mic always dies soon afterwards.
Please help!
