help with an I2S DAC and pigpio interferences

hello
I am working on a radio with pCP plus Rpi Zero W where I add an I2S Rpi DAC (Adafruit MAX98357a).
I also add an I2C display, a couple of buttons and a rotary encoder.

To control the buttons I try to run "sbpd", but as soon as I start the pigpiod, the sound get interferences and distortions. I think it's a problem with I2S interface clock, but I'm not sure.

I have tried the "-t 0" parameter in pigpiod, but no luck.

Any idea how to fix the problem?
Maybe I missed some parameter or settings?
Can I control the buttons and the encoder in another way than using pigpiod?

Thanks to all.
