Volume settings V2 with IQaudIO DAC+ with AMP+

Hi, one of my RPis wears a couple IQaudIO hats. It has the DAC+ and the AMP+, i.e. It’s a complete item with no other kit except speakers. I’m not sure how I should set the volume settings in Volumio v2. I just deafened myself and I don’t want to risk blowing the speakers. Guidance would appreciated.


Choose hardware volume, but I suggest to set a max Volume as well (start with 50, that should be enough).

Let me know

Thank you.
Can you explain the choices under a Mixer Control Name?
