Hi,
I am getting a lot of noise when using the speaker phat with raspberry pi zero w. Previously i had no issues. But recently i had used hw pwm to control motors along with speaker phat. The problem has appeared since. How can i fix this.
Thanks,
Check for pin conflicts. If your motor controller is using some of the same pins the speaker pHat is using that’s likely your issue.
I disconnected the motor controller. Still i am getting noise. Also there is this message appearing on the desktop failed to load overlay i2s-mmap on bullseye. I also tried buster but the issue persists.
Fresh, started from scratch, installs?
Yes, lot of noise on fresh install of bullseye and buster. Could i have damaged the speaker phat by running hw pwm motors and speakerphat simultaneously.
It would seem that’s what happened?
