Question about RME Audio ADI-2 DAC FS

I am thinking of getting an HD660S2 and an RME Audio ADI-2 DAC FS. 1. is it possible to use an Nvidia Shield TV / KODI as a player via USB ? According to the technical data, this should fit, I think: (High resolution audio playback up to 24 Bit/192 kHz via HDMI and USB) High resolution audio upsampling to 24 bit / 192 kHz via USB Audio support: AAC, AAC+, eAAC+, MP3, WAVE, AMR, OGG Vorbis, FLAC, PCM, WMA, WMA-Pro, WMA-Lossless, Dolby Digital Plus, Dolby Atmos, Dolby TrueHD (Passthrough), DTS-X (Passthrough), and DTS-HD (Passthrough))
