UDA1334A I2S DAC outputing only noise

[Windorey]

Hello, I have recently purchased the breakout board mentioned in the title, but when I connect it to my Teensy 4.1 board, I only get noise output, however, if I solder them directly together I do get an output. This is not an issue with my ESP32, even on a breadboard it works fine. Any suggestions on what to do are welcome.

What I am sure about:

• My code is working

• The I2S output is working

• The connections are correct

• The audio data type is correct

Post a photo showing your hardware and connections and we'll take a look. 800x600 images usually work best.

Thank you for your reply. Currently I am unable to take a photo, but a few days ago I filmed a video.
I figured out it does actually work, but only when I touch the pins. Here is a video demonstrating it:

I have now decided I want to use an external Master Clock instead of having the built-in PLL generate it for me. How do I do that? The GitHub repository says it's possible but gives no info on it.

That noise is probably the clock signals, capacitively coupled to the Vin pin through your fingertips.

The UDA1334A doesn't use the MCLK signal. In audio mode, it generates its internal clocks from the WSEL signal.

There's a video mode where it can accept a 27MHz reference clock from the SCLK pin, but that's different from basic audio playback.
