So I got new DAC modules today and it's working just fine with both I2S and a2dp_sink examples... the new modules are kinda simpler and have usefull solder bridges simplifying the "settings" of the DAC chip. Guess BCK is fine, but i'm still confused why BCK is so different. I'll do some testing to f...

@Jakobsen i used the i2s example and not the a2dp_sink example for the pictures. there the sample rate is defined as 36000, so everything fine with the wordclock. in the source: https://github.com/espressif/esp-idf/blob/master/examples/peripherals/i2s/main/i2s_example_main.c#L21 @jgustavoam as state...

I took the photos of my scope with the simple i2s example running (changed the pins in the code to match the default pins from the a2dp_sink example). As the i2s example cycles through the bitlengs the bitclock is changing (which it should i guess) but it looks off to me, it has an offset and pretty...

Thank you for your answer Jakobsen. I testet the suggestions but had no luck. The grounding and supply voltage seem fine. I also tested with headphones but still nothing. I took some photos so maybe you can figgure it out. I also took photos of my scope. Wordclock and Data lines seem fine to me, but...

Hi, i'm trying to get sound out of my esp32 (wemos D32 Pro) and bought a PCM5102a-Module. I don't have much experiences with microcontrollers and the esp32, so i tried the esp-idf examples first. I tried the peripherals/i2s and bluetooth/bluedroid/classic_bt/a2dp_sink, but both did not work. With my...
