ESP32A1-S

[Udaymakxenia]

I had been using your library with the Ai-Thinker Audiokit and everything works fine. But for my final product I wanted to use the ESP32A1S chip . But when I upload the code to the chip the library says that the board is not initialized. Does audiokit only support the board or does it also support the ESP32A1s chip? Can you suggest examples to test the chip.

I don't see any reason why this should not work - assuming that you were setting the the AUDIOKIT_BOARD to a value with corresponds with the audio chip provided by the ESPA1S!
Does it have a AC101 or a ES8388 ?

Can you provide the output from the log ?

This is the log . My board has ES8388

Obviously the I2C communication is not working: so double check if you connected the right pins.
Maybe they also need to be pulled up?
See i2c pins

Thank you phil I got the issue solved it was actually a AC101 chip. But now while I play it using a speaker the sound output is very low. I tried with volume (1.0) still the output is very low. I use a 4 ohm 3 watt speaker which should provide a pretty good output. Is there something in the code that I should enable. I tried the same speaker with the audiokit and the output is still low.

[pschatzmann]

Hmm, I have an AIThinker AudioKit which is based on the AC101 and it is actually pretty loud.
So I don't think that this is related to this software.

[Udaymakxenia]

Oh. Mine is the ES8388 version audiokit . I thought there is a PA Enable on the code. The voltage I get from the output is 2.5V peak

[pschatzmann]

I moved this logic from the AudoTools to the AudiKit begin method. The PA is enabled if you do not specify the earphones as output device
