Support for audio in the USB driver?

[dpotop]

Hello,

I've looked into several bare metal USB drivers (Circle, USPI, CSUD) and I can find no support for audio beyond MIDI.
Has someone worked on things like reading data from a USB microphone and possibly pushing sound to USB
speakers?

If such a driver does not exist, could this document allow me to write one ?

Addendum - I found something in Ultibo.

Does anyone know the status of Ultibo? The last news they have is from May 2018...

Cheers,

SimpleAudio is the audio driver for the audio jack only. It doesn't support any other audio devices (USB, I2S, HDMI).
