Hi Thomas!
Great to hear from you too, and that you were able to get the power button working on the Audiophonics Network Player. I bet you were relieved when it stopped blinking! 😉
Perhaps (probably!) I am missing something… when I SSH into the IQaudIO RPi and enter ‚amixer‘ I get the following output, and no indication regarding whether to choose ‚Digital‘ or ‚Master‘:

EDIT: Since I have disabled to on-board audio of the RPi3, is it possible that that is the reason why it does not differentiate between Digital and Master, i.e. amixer only „sees“ one audio device, the IQaudIO?
An updated Power Button how-to with your edits would be great, aber kein Stress… 😉
Best regards,
