USB Audio headset
Overview
This sample app demonstrates use of a USB Audio driver by the Zephyr project. This very simple sample that performs loopback over IN/OUT ISO endpoints. The device will show up as single audio device.
Building and Running
In order to build the sample an overlay file with required options must be provided. By default app.overlay is added. An overlay contains software and hardware specific information which allow to fully describe the device.
After you have built and flashed the sample app image to your board, plug the board into a host device.
Testing
Steps to test the sample:
Build and flash the sample as described above.
Connect to the HOST.
Chose default Audio IN/OUT.
Start streaming audio (for example by playing an audio file on the HOST).
Start recording audio stream (for example using Audacity).
Verify the recorded audio stream.
