Answers checklist.

• I have read the documentation ESP-IDF Programming Guide and the issue is not addressed there.
• I have updated my IDF branch (master or release) to the latest version and checked that the issue is present there.
• I have searched the issue tracker for a similar issue and not found a similar issue.

General issue report

Hello, I am creating an issue post about this because it seems the only related issues are long closed. I am attempting to test out the speaker function of the new P4 kit, but when running this example I am getting no sound.

I (174110) i2s_es8311: [music] i2s music played, 640000 bytes are written.

is printing out over and over but nothing from the speaker. I saw an issue related to the P4 board about switching the DI and DO pins but that issue was fixed and closed. I tried it anyway, still nothing.

Is there anything I am missing that I could try?

Have you set the correct GPIO according to your P4-Nano board? https://www.waveshare.net/w/upload/9/97/ESP32-P4-NANO.pdf

ESP32P4 I2S_DO_IO is connected ES8311 PIN9-SDIN, from the schematic it's GPIO9, so please set it correctly in the example_config.h.

Please note, esp-idf example doesn't contain any BSP package, there's no guarantee that it can run out of the box for all boards on the market. We expect the user will read the README before trying the example.

This issue probably caused by the PA (Power Amplifier) is not enabled. According to the schematic from the link above:

The PA_CTRL (which is connected to GPIO53) need to be at high level to enable the PA. You can either set GPIO53 to high in the example, or just connect GPIO53 to VCC with a jump wire.

BTW, P4-EV board also uses GPIO53 as the PA_CTRL, PA is not enabled by default on these P4 boards, please take care when using P4 dev kit~

Back to the example, the example can't ensure whether the PA on board is enabled by default or connect to a particular GPIO. So, the PA enable step won't be added into the example. But I think we can add some hints since this issue is pretty common for P4 boards.

And thanks for the feed back! @Ncouch64

I appreciate the assistance here, still new to the ESP world so figuring things out as I go along. I will try what has been posted here and provide an update. Thank you!
