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!

Hi,
Please find below answers for your questions
1. You can control the mute of your AMP with the GPIO22 of the RPI. In the BOSS board,GPIO22 comes on 14th pin of J19 Connector.
2. You can control the mute of the DAC with the GPIO6 of the RPI.
3.13th pin(GPIO23 of RPI) of J19 connector is used for shutdown control of VOLT AMP board.
With Regards

Thanks, however I do not want to control the mute manually, I want the Boss DAC to control the amp mute automatically based on the auto mute login the the Boss DAC. So when the Boss auto mutes, it should bring pin 14 low and when it un-mutes it should bring pin 14 high.
Is that possible? Can a driver update introduce that functionality?

You can use 20-pin PSUs in a 24-pin mobo.No need to use any converter but u should use a 24-pin PSU so that your board get enough stable power.
