One issue that I have run into is that it seems like the audio from Amazon Music (my preferred streaming app) is not getting routed around the android audio. I've tested this with ultra HD songs, regular HD songs, and standard songs, and regardless, the bit rate indicator at the top left of the player displays 48khz. The app correctly recognizes that the DAP supports 24bit/192khz files, and indicates that it is playing files at their native bit rate (24/44.1khz, 24/96khz, etc), but the bit rate indicator at the top left indicator bar of the DX300 always indicates 48khz. I first installed the app through google play store, then uninstalled and reinstalled the app from Apk Pure, but ran into the same issue. Is Amazon music working correctly for anyone else? Any ideas?
