For some reason it is turned off in the ESP32_GENERIC_C6 build. See #define MICROPY_PY_MACHINE_I2S (0)This used to be the case for ESP32_GENERIC_C3 also, but that setting is removed. The default is defined in |

Yep. That builds and makes I2S available in machine. I did not try, if it works. |

I was able to build a ESP32_GENERIC_C6 successfully ( I think the I2S in in the build, I noticed that the module was compiled: micropython/extmod/machine_i2s.c.obj) but have run into an invalid image block. ets_main.c 331 with the following details: bin file is roughly the same size as the recent generic release. First time I've tried building mp. Did I miss a step? |

Sorry- I do not have a C6 to experiment with.

I understand. Since I'm new to this, I think I'll first verify that I'm able to correctly build a generic ESP32 . After that I'll try to look for other settings that may interfere with the capabilities of the particular XIAO C6. Any other suggestions would be appreciated. |

Using mpbuild can save a lot of time and setup headaches. https://github.com/mattytrentini/mpbuild?tab=readme-ov-file#mpbuild |

I was able to add I2S to the ESP_GENERIC_C6 build. Setting the worked. So is this a bug? I don't feel like I should do a PR unless it is the only way it will get picked up. |

Verified operation on XIAO ESP32-C6 with following pinout. Using Mike Teachmans I2S examples as test cases. I2S Board was generic PCM5102 audio generator with 3.5mm output.

Great. I'm stumbled on this lack of I2S for C6 as well. Can you provide a PR so that it gets into the main build? |

Thanks for doing the PR. I still have the XIAO versions of the -C6 if any additional testing needs to be done. |

I would appreciate if you can test if it works for you. I'm unable to get it to work for me. Although, I'm expecting it to be my code it would be nice to out my PR. |

What do you use for playback. I have a PCM5102A and I'm starting to suspect that I have the same issue as here |
