ESP32-LyraT V4.3 with ES8388 support

[Omirax]

Hello!

Unfortunately, only headphones work for ESP32-Lyrath V4.3 with ES8388.
The microphone and speaker do not work, although all pinouts are the same:

Could you take a look at what the problem might be?

Hi @Omirax, I do not have such a device so I cannot test it myself. The code seems to work because the logging shows no error.

Hello!
Unfortunately, as I wrote earlier, only the headphone output works. It is possible that this is due to the fact that both ESP32-Lyrath microphones are connected to the ES8388 pin 23/24. While contacts 21/22/23/24 are used on AI

This is ok?

[Romkabouter]

Yes, that is ok. That is the state of the state machine.
Your intent was not recognised (no mic is working) and then Rhasspy sends an error (+sound)
That is the logging you see.

It is possible that there is a problem with the pinouts difference, your link at the top is not for the board with ES8388, is that correct?

I found all the little problems and shortcomings with the volume and playback quality.
But I still couldn't figure out why the microphones aren't activated.

@Romkabouter Maybe you have some ideas?

[Omirax]

@Romkabouter
Work with es8388_write_reg(ES8388_ADDR, ES8388_ADCCONTROL3, 0x02);

[Romkabouter]

Well, PR's are welcome but I do not have such a device so I cannot test it and therefore will not change code myself

[Omirax]

#define ES8388_ADCCONTROL3 0x0b
...
ES8388 User Guide: es8388_write( 0x0B 0x02); // Reg 0x0B = 0x02 (Select LIN1and RIN1 as differential input pairs)
ESP32-LyraT Use only LIN1and RIN1 for mic input. LIN2and RIN2 - for AUX

@Omirax Are you still trying to find a solution?
