Hello, I'm using board with MAX98357A chip and Raspberry Pi 4 model B.
I followed examples on this link https://learn.adafruit.com/adafruit-max ... y-pi-usage
After rebooting I see BCLK and LRCLK signals on oscilloscope but there is no DOUT pulses (only zero logic level) from GPIO21 of Rasberry. As a result there is no sound from speaker.
I tried Raspberry Pi CM4 board with IO Board but result the same.
So, Do you have some ideas how It can be fixed.

Re: MAX98357 issues
What OS image are you using?
Did you see any errors when you ran the install script?

There is no errors. Everything goes as it described in adafruit manual.

Re: MAX98357 issues
Thanks, that should all be fine.
Were you using the Fast Install or the Detail Install approach when setting things up?

Can you post a photo of your setup so we can look for anything that might be wrong with the hardware.

Re: MAX98357 issues
Thanks for attention.
Everything is solved.
After second rebooting I re-ran the script and choose N the /dev/zero playback service.
Than sudo reboot and after that i2s started working.
