This project will add USB audio to the HDMI2USB firmware. It will allow the FX2 USB module to present itself as an audio device as well as the current video device. USB audio is a much needed addition as it reduces the number of required cables when setting up a presenter’s laptops. It also has applications for other sources as many HDMI capable devices send their audio over that HDMI connection. Note that this does not include the HDMI capture side of the audio.
