No sound from speakers

Hello.

I've problem with installing drivers for Raspberry PI OS Full. I created dedicated module using PCM5102A and PAM8403. All works fine when i setup new Raspberry PI OS Full at then new SD card, but when i have to install drivers on existing OS, evrythings looks fine but finally speakres do not play any sounds. I have to update about 70 RPIs so i dont want to reinstall whole Raspberry PI OS.

What can i check more?

In addition i'm using a lot of GPIO eg.
-LCD Display via SPI
-NFC Reader via I2C
-RGB Diodes via GPIO 13 (PWM1)
