Bluetooth audio from windows PC has a high pitched noise and is quiet.

Hey first thanks for making this project, it's pretty awesome. Secondly I know you've moved the project to mpradio-py, but for the life of me I cannot get it working on my raspberry pi zero w, so i just installed one of the precompiled images. Works great.

My issue is when I'm playing BT audio from a windows 10 pc, there is a persistent high pitched squeal.
This seems to go away when i'm using an android phone.

Thanks in advance for any insight.
