Hello Heiner,

the hardware volume control is not working yet – I believe it´s a mixer related issue – any idea how to fix?
My soundcard is from your bundle (7# touch display, PI 3 and IQaudIO PI-DAC+)

I used following command line in the extended shairport options:

-t hardware -m hw:0 -c Digital

Error Message:
Versucht zu starten … NICHT Erfolgreich Hier klicken für weitere Informationen
The alsa backend -t option is deprecated and has been ignored. FYI, using the -c option automatically chooses a hardware mixer.
Failed to find mixer element

amixer output:
