I had a similar issue where the volume wheel was a bit tight and there was almost all noise from the speaker.
Immediately following the first boot up, the sound seemed to work great, but after a little tinkering the sound went all noise.
First, rather than cutting the case around the wheel I simply loosened the bottom corner case screw, which relieved the pressure and the case is plenty secure.
I then went into the RetroPie --> Audio menu and chose to 'reset' the ALSA sound, which helped quite a bit with game sound but the noise was still present.
Then i added 'audio_pwm_mode=2' to the /boot/config.txt , and that totally fixed the Noise issue!
Ed i would suggest updating the retropie image file with the audio_pwm_mode setting, as i would think all users would need this on the zero-w
