4th Generation Apple TV as a music streamer

Has anyone tried to incorporate the latest 4th Generation Apple TV as a music server (either streaming directly from TIDAL or playing from downloads made to the onboard storage)? According to the Apple website (https://support.apple.com/kb/SP724?locale=en_US), the 4th Generation Apple TV supports the following audio formats:

• HE-AAC (V1), AAC (16 to 320 Kbps), protected AAC (from iTunes Store), MP3 (16 to 320 Kbps), MP3 VBR, Audible (formats 2, 3, and 4), Apple Lossless, AIFF, and WAV; Dolby Digital 5.1 and Dolby Digital Plus 7.1

I was curious if the internal DAC could be bypassed in favor of an external DAC, and then how this might be connected (as the 4th Generation Apple TV has no optical or USB outputs). I don't know if there is a converter box that will take HDMI 1.4 (the audio portion) or 10/100BASE-T Ethernet and convert it to USB, SPDIF or AES/EBU XLR... as those are the inputs accepted by my external DAC. It would be nice if the 4th Generation Apple TV could take the place of my Mac Mini as a music server.

Perhaps more importantly, can the 4th Generation Apple TV handle up to 96 kHz/24bit or 192kHz/24bit AIFF music files?

 

I found this HDMI audio converter, but I am unclear if it has an internal DAC (which I am trying to avoid, since I want the original audio signal to be processed by my external DAC):

Of course, more searches may uncover an audio converter with better specifications. I also don't know if adding this to the chain will degrade my audio signal.
