wifi calling in Pixel 4a 5g, I can't hear

I bought a pixel 4a 5g straight from google. It's fully stock. When I'm on WiFi calling, I almost always (not always though) can't hear the other side on the call and have to switch to cellular. The other side of the call reports hearing me without an issue.

 

My phone is fully updated with google updates.

I'm having the same issues on Pixel 5. The other side of the call says they can hear me fine, but I can't hear them. The only fix is to disconnect from wifi. 

Did anyone find a more permanent fix?
