I have my Arylic B50 connected to my computer using USB. (DAC mode)
Up2Stream USB Audio is selected in my audio settings.
Sony MX10003 Bluetooth headphones are connected to the Arylic B50.
When playing music on Amazon Music (ULTRA HD) for some tracks the audio is listed as follows:
Track Quality: 24 bit / 96khz
Device Capability: 24 bit / 48khz
Currently Playing At: 24 bit / 48khz
My Up2Stream USB Audio has 16 bit / 48000 hz selected (DVD quality)
Should I believe Amazon Music? Or is the Up2Stream audio what I am hearing in the headphones via Bluetooth?
