How to use the AudioDriverES8311 to the fullest.

[nielsnl68]

For my combadge i just switched to the new M5stack Atom EchoS3R.
This small unit uses the ES8311 and NS4150 as Speaker Amp.
To see how it all work i'm doing some test using the rtttl class. At first i forgot to add that the NS4150 has an enable pin to be set true. So i added the basic pinmode() and digitalWrite() functions to enable this pin and it did work perfect.
Then i saw that the AudioBoard Class could also control this pin using the PA pin configuration. But i'm missing something i belief, because i do not get any audio out of it this way.

Not sure: I suggest that you set the audio-driver library to debug mode.

It might also be a good idea to define this device in the audio driver library.

It was already very late and i did not rebooted the device manual, that seems to be needed with it.

I will look into it to make it a device for the audio driver.

I committed a DRAFT implementation.

Thanks

Now that this part works, could you give me some hinds on creating a bidirectional setup using the above and the espnow configuration, I think i have slightly an idea on how define the pipelines, but how to no clue what to do to setup it so that we need to click the button to start sending audio and a second time stopping it again.

I also saw somewhere on you repo's that you where working on a echo_canceling solution but now i cant figure out where i saw it. I like to test that as well in the near future.
