DAC installation issues [solved]

[Alexus-3000]

Please help me: I connected the 1602 display with i2c, the HW-040 encoder, and the PCM5102A DAC to the Raspberry Pi Zero.

After that, the system freezes

Can you post a photo of your hardware, especially what is wired to what on the GPIO header, and your minidexed.ini file?

The error-sounding messages you have here are pretty typical and nothing particularly unusual.

Does it do anything if you don't power up with the USB device attached?

I figured out almost everything. Everything works via hdmi. There is no sound through the DAC. Everything is connected as in the sample on the website. I changed the DAC, there is no sound.

Are the solder jumpers correct on the back of the DAC? Details here: https://github.com/dwhinham/mt32-pi/wiki/GY-PCM5102-DAC-module.

I made jumpers. It hasn't worked yet, there may be soldering defects. I will continue to experiment

And check the tiny solder bridges on the other side vs. what is in our wiki.

So far, I have installed the CJMCU 5102 DAC module. Works.

I plan to replace the encoder with buttons. If there are examples of schemes and the minindex.ini file, I would be very grateful!
