Apps like Audionirvana (Roon is another) operate in "Exclusive Mode" on MacOS, which means they're able to automatically take control of the sound output and dictate the bit depth and bit rate of songs to MacOS without requiring adjustment in Audio MIDI Setup. Apps like Amazon Music (and Apple's own Music app, weirdly) don't operate in Exclusive Mode and therefore need adjusting in Audio MIDI Setup on an album by album basis (which is a ridiculous way to do things and makes MacOS very frustrating in this respect). In my own experience, LosslessSwitcher works pretty well with Apple Music and the Music app, but I don't use Amazon Music, so I can't comment on that (and I may in fact be wrong about it not having Exclusive Mode, so I would check for that first).Thanks for both replies. @turbo87, I looked up the LosslessSwitcher on GitHub, and release notes say that it automatically switches audio devices to the bit rate by song played in Apple Music (mentions this several times). I use to Amazon Music for streamed music, and AudioNirvana for my own high res files. Not sure Lossless switcher will work on these other apps. @Kentajalli, I'd like to make sure I understand what you're saying "If Mojo reports it is receiving 192kHz, then it must have happened beforehand." As I mentioned, for some reason the Mojo 2 doesn't automatically adjust to the changed resolution in Amazon Music, but does automatically switch within AudioNirvana, which causes me to believe that the issue is the way the music playing app is "delivering" the music to the Mojo 2 via USB. Will now look through the Amazon Music forums. Thanks again!
