Okay may be it switches automatically but disabling it does not make sense such enhancements are good and improves the overall experience. Any idea where can I find some hi res content? Also any Asus person can confirm this behaviour?ColorSage said:Hi-Res doesn't work with "default output" because it is determined by audio source. If a player generates Hi-Res audio output of let's say 192 kHz DTS will detect it and disable itself to avoid sound alteration(I guess that was the idea). In other cases, ie system sounds, Spotify, Youtube audio output is 44.1/48kHz so it will not be Hi-Res.
