Nexus 7 2013 + USB DAC Fioo E10K (stock rom, rooted) http://fiio.net/en/products/27
Hi res audio on Poweramp only support 24bit-48Khz (according to output status) whereas the USB DAC should able to playback 24bit-96Khz. Any ideas? Attached is the audio_policy.conf and below is the /proc/asound/card2/stream0 file while playing back audio from poweramp
