Hmm, I've been playing around with Atmos/DTS with headphones and neither of them work at above 16/48k. That's unfortunately and makes anything above that sample rate practically useless for gaming. after listening to music on the highest bitrate all day, that 16/48k sounds like crap. Also, the issue with the DAC disconnecting and having to be restarted seems to occur when I am using the highest bit/sampling rate. It disconnected during game play and the game had to be completely restarted after restarting the DAC to restore audio.
