Hi,

I would like to mute my amp when the Boss DAC is not playing any music, could you give me some more info on the mute amp pin on the J19 connector?
Does it operate in parallel with the auto mute function of the DAC? Or do I have to use the GPIO calls via code?
What are the states at DAC mute and unmute?

What about pin 13? When is that active?

Thanks!
