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.

Have you made any progress? I've run into the same issue as you on Zero 2W, no output from DAC but HDMI output works. I've checked jumper pads and everything, but it didn't help

[Alexus-3000]

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!
