The folks over at raspberry pi just announced that they will officially support and sell the iq audio products under the raspberry pi brand:
Very interesting boards and features. I will definitely look at the raspberry pi zero size hat that will arrive in the new year. It has a build in mic and a speaker amp plus a green and a red led on two gpios. It also has a mono mic in.

Would not be so glib.
Just dropped this here for information not to start a discussion about the pro and cons as non of us have used these.

If I am playing audio then I want AEC and that sort of puts a mocker on it for me.
As said the https://www.microchip.com/wwwproducts/en/ZL38063 would be great but for voice AI the Dacs do come with a few problems if for use that way.
