hi can you give me the microphone connection diagram, and are the 2 microphones working fine?

Hi All

Ive tried everything to get this working with no luck, anyone willing to help.
Please

I am having trouble running an INMP441 and the max 98357a amplifier. They are sharing the bus as in the original design here.
The amplifier is running on the left channel (by default), while the microphone is on the right (pulled up to 3.3V).
The wakeword is working but the speaker is giving an error message: "Parent bus is not free".

Running a minimal sketch with only the speaker I can get the media pipeline to work. Announcement is not outputting anything.

Did anyone encounter the "parent bus not free" error?
Did anyone get this to work on a shared bus?
