I've not used it, but the audio tool does appear to support USB audio:
There is the example: Audio -> HardwareTesting -> WavFilePlayerUSB that plays songs from the SD card to USB output.
You would need to set the USB type to one of the types that support USB Audio:
I believe this is for the normal USB connection, and not the USB host connection that the Teensy 3.6, 4.0, and 4.1 provide.

- Audio
- Serial + MIDI + Audio
- Serial + MIDIx16 + Audio

This is indeed using the teensy as an audio device.
I was looking at connecting a usb audio card to the teensy used as host.
Just another way to output audio next to SPDIF, I2S...
I am experimenting some problem with my VGA library while outputting audio to I2S or SPDIF simultaneously. Just wanted to try over USB if it ever did exist...no pb....
