[Bug]: Talkback Audio does not work fine
### What happened?

Hey there,

I use a T8200 Video doorbell and want to use talkback Audio.

The problem is, that there is just some fancy noise when I want to speak to the doorbell. Hearing is fine so far.
I'm using a Rapsi4, thats why I only can use less resolution.
