I have a StickC and a StickC+ and with both the Speaker Hat make a lot of noise when is enabled. This happen on UIFlow and on Arduino environments.
If I a usa a cheap PAM8403 extenal amplifier the noise goes away, therefore the problem is in the Speaker Hat.
I have two Speaker Hat and both produce a lot of background noise.

Am I the only one experiencing an high level of noise with the Speaker Hat?

I need to record the audio from stick-c internal microphone and I want to use python.
I found a couple of examples that show how to play the audio in python via I2S internal dac:

• Play WAV Files on Your M5Stack
• M5Stack RFID Face Wav Playing Flashcard Program

Instead I can't find anything in python for recordind audio via the integrated microphone. I found an example for Arduino but I don't know how to port it in python.

Can anyone help me?
