I am new to the RPI world, but I am liking it. I have purchased a RPI3 and a DIGI+ card I have installed KODI and everything is working fine. On a set of desktop computer speakers. The project objective is to put this setup in my truck. I am trying to control the volume and other than a SKIN I have not had much luck. I would like to install a volume knob and was woundering if any one has worked with this setup. I see a lot of DAC+ but no DIGI+ I should note I am trying to use the optical output. I have sent the optical signal to a converter to split it to 5.1 surround. That is working but no volume control is putting a damper on it. Does anyone have any suggestions.
