Just reading the trouble-shooting section in
http://www.iqaudio.com/downloads/IQaudIO.pdf

Running dmesg has the following errors on the snd card:

[ 3.509569] snd-rpi-iqaudio-dac soc:sound: ASoC: CODEC DAI pcm512x-hifi not registered – will retry
[ 3.709710] snd-rpi-iqaudio-dac soc:sound: ASoC: CODEC DAI pcm512x-hifi not registered – will retry
[ 3.730279] snd-rpi-iqaudio-dac soc:sound: ASoC: CODEC DAI pcm512x-hifi not registered – will retry
[ 4.045982] pcm512x 1-004c: Failed to reset device: -121
[ 4.046527] pcm512x: probe of 1-004c failed with error -121

But googling for the errors did not give me a helping hint so far.
