There is noise for recording if I run below pipewire command to record with 44.1k on Pi4 which installed latest PiOS based on Debian12.
pw-record --rate=44100 --channels=2 --format=s16 pw_record1.wav

OS version:
Distributor ID: Debian
Description: Debian GNU/Linux 12(bookworm)
Release: 12
Codename: bookworm

The issue only happens on Debian12 PiOS, not happen on Debian11 PiOS.
The difference is that Debian12 uses pipewire as the default audio engine.

Also, both playback and recording have noise what ever sample rate is on Pi5 with debian12 PiOS.
