Support for audio in the USB driver?

Thu Jan 16, 2020 8:28 pm

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,
