I haven't tried using the HDMI output for audio. I have used the USB output but this wasn't satisfactory because the Ethernet port uses the same USB controller and this produces audible interference (clicks, pops and dropouts).

See above. I have also used the I2S output to drive the Wolfson/Cirrus Logic card and the results were much better than USB.
