Hardware volume control in cs42l43 can go up to +31.5dB which can cause audio degradation. For best results, keep the hardware volume set to 0dB and let software volume control the output.
It's something which I dislike (software volume control). If there's a hardware limit, it should be added to the driver. Eventually, alsa-lib plugins may be extended to do this cropping using a configuration. Also, it may be a bug in pulseaudio/pipewire. The +0dB volumes should be handed with a care.
