Using DAC ouput to amp instead of I2S

[griffinmt]

It is not clear (to me at least) what I need to do or set up to have the audio output use DAC instead of I2S. I am using a PAM8302 with attached volume control and running ESP-NOW. Any and all help would be appreciated.

The code is not currently set up to output to the DAC, but o think to should be straightforward to make it work. I'll have to have a look.

I would truly appreciate it.

Looks like it's already there!

in the config.h file, just comment out the line:

#define USE_I2S_SPEAKER_OUTPUT

Already tried that but no change. I tried commenting the other 4 i2s speaker lines, but that just raise errors.

your description states the following:
" modify the code to use the built-in DAC for output "

[cgreening]

That should be all that's necessary - that will start writing samples out to the DAC.

Might be worth running a simple test to make sure you can output audio normally to the DAC and sound comes out.

I've been trying to achieve the same, but so far no result. I think it's something simple with defining the pin of the built-in DAC somewhere (GPIO 25 or 26), but I can't seem to figure out where to put this.

Can you check it again, a lot of fixes were made to the I2S implementation
