Set to listen for 3 seconds, but have tried other settings. This was working perfectly on my old Pixel 2XL, but recently updated to the Pixel 4XL and now all I ever get is 0 from Current Noise. AutoVoice has no permissions denied, is not battery optimized. I have also turn on "Control Noise Listener" under Ambient Noise, but that doesn't seem to fix it. Is there anything else I can do?
