I have problems to reproduce any sound through the audio injector Octo.
Any sound  is reproduced just  like noise.

How can I solve this problem?


I’m using a Respberry Pi 4 with OS Raspbian Bullseye


And tanking advantage of this mail. A second question:


Which GPIO use Audio Injector? I would like to connect  some sensors, and I don’t know which GPIO are available.

Attach a sample of the Audio Injector Sound:

Thank you.
