Got myself a new headphone amp/dac (Xduoo X5 plus), which has a display where you can read the samplerate of the connected source device over USB, in this case the A50 is the source. I noticed that the A50 doesn't send a bit perfect (original 44khz) audio signal but an upscaled 192khz one.
It shouldn't do that by default. I tried my old Galaxy S5 and this one does it right, it sends 44khz.
In the A50 menu there is a hi-res setting but this doesn't affect usb audio, only the internal da converter.
