[andyvans]

Hi Phil

I saw this video that uses an espressif example to send and receive USB audio from and esp32.

I also saw you have a sandbox version of usb audio protocol. Are these working? I was wanting to stream mp3 to a USB audio sink that that is plugged into an amplifier. I think I would use the USB host port of the S3

No, not working yet.
I want to have a solution that works on all environemnts and not only for the ESP32.
Unfortunately the TinyUSB integration is working completely differently on the ESP32 than on all other environemnts

Please, @pschatzmann what is your opinion on the matter? Will it be possible in weeks, months, or years? Or am I misunderstanding the current stage of development? Is it possible already to have, say i2s to uac conversion on rp2040 or esp32sX? Examples for PicoSDK and ESP-IDF gives quite little of optimism...

[pschatzmann]

For the rp2040 and other non ESP32 platforms I have a proof of concept that I plan just to leave as that.
For the ESP32 you can try this library.

For my planned platform idependent version, it will be rather months if ever ...
It's the next big topic on my todo list after completing my current dlna project.
