Mic stream returns mostly 0 in iPhone 14 and later.

[manish3008]

listener = stream?.listen((value) {
log(value.toString());
_audioStream!.add(value);
});

when I am printing values for iPhone 11, 12 and 13 , it is working fine as I am getting values between 0 t0 255,but with same code when running in iPhone 14 and 15, I am getting mostly 0.
