Success!!!!
That is the 2nd time you have given me a solution!
I re-read what you typed - hooked it up again - I hit the lot up icon, and sure enough - I had sound! This will be very helpful this weekend - I have a headphone meet with several friends, and carrying a DAP and connecting it to my DAC is a much simpler set up then the Aries renderer - and, I can connect it to the Chord Dave, the HoloAudio Spring, etc. DACs that will be there.
Now, if I could only figure out the AK Connect......a dealer suggested that I can control the SR15 using the AK Connect app on my phone. Don’t see that option in the manual - I downloaded the app - shows like a player - like the Onkyo app - I can connect to the Synology NAS and play everything through my phone, but that is not helpful
