Hello!

I use an example from the AG library and I can't connect a wide-band headset to my application.

Narrow band headsets work fine - there is audio.

But when I connect the wideband - there is no audio.

Would you like to see if I am using the wrong settings? Or the chip simply does not support the wideband?
