Sorry to resuscitate this thread. But I want to use my Topping as Shield TV output, but the problem is how to manage the audio I want to play. What program should I use?
The Shield allows to use its own internal DAC, which it does have, or passthrough it to the AVR you are using. The OS on the Shield is Android, and AFAIK those two I mentioned are the only two output digital options I have.
Kodi was the program I was using, and I find its music playing having less quality than another option I tried some time ago, with a Raspberry loaded with a Linux audio management program, Picoreplayer, and using the Rasp USB output into the Topping DAC. But the Rasp had its own screen and remote control.
In this case, to use the DAC I would have to use the AVR analog input that has no interface with Kodi to control the player options.
Let's hope I'm being clear on what the problem is.
