Hi Ethan,
Apologies for the delayed response. I don’t have an AIY Kit myself and based on the feedback from other users here, it goes through stages of working or not.
Can I check, are you using the latest Picroft image dated 2019-07-20? I know some fixes got pushed with that image.
Have you already had a look at our audio troubleshooting guide?
There are also some detailed instructions that others have posted for work arounds they have used.
We do try to maintain support, however it’s a constantly moving target and changes made at different layers of the audio stack outside of our control can have adverse impacts.
