1. Sony Xperia Z4 Tablet
2. 6.0.1 official ROM
3. official specs indicates it supports 24-bit 192khz output, alongside with DSEE HX upsampling (3.5mm output only), aptX and Sony's Hi-Res audio etc.
I'm wondering if Poweramp is able to upsampling a low bit rate file and then output to a aptX/Hi-Res bluetooth device, since DSEE HX doesn't work for wireless protocol...
