Adafruit Voice Bonnet has a high pitched whine

[NightRise]

My situation essentially mirrors this post: viewtopic.php?f=50&t=183052&p=889886&hi ... et#p889886

I purchased an Adafruit Voice Bonnet for Raspberry Pi on September 3rd 2021.

The Bonnet's mic's have a consistent high pitched whine. The speakers work fine, but the microphone is essentially unusable due to the pitch.

The bonnet was installed on a raspberry pi 4b 4gb with a fresh install of raspberry pi os buster light.
The software was installed according to these instructions: https://learn.adafruit.com/adafruit-voice-bonnet
I've tried multiple speaker configurations, and used a pre-recorded test file to narrow the issue down to the mic.

What do I do?

@NightRise,

We can try a replacement or if you prefer a refund.

I'd prefer a replacement since I already have the speakers and such to match
