i Am using Xiaomi Redmi Note 4 Snapdragon 625. in Marshmallow 24bit/192khz was working fine in Poweramp Alpha but after Updating to Nougat That Option is Gone , No more Hi-res..
Why is that .. ? is Nougat Not Supported. ? ANy way to get that option Back.. ?
I encountered a same situation on my device.
LGE g3 variant, snapdragon 801ac SoC
Android 7.1.2 lineageos based ROM
Poweramp 704 alpha
Poweramp detects Hi-Res Output, but it fails when I selected it.
After some investigation, I found out that Poweramp seems to use AudioTrack without AUDIO_OUTPUT_FLAG_COMPRESS_OFFLOAD flag when it fails.
(I believe we need the flag on my device because audio~policy.conf has a compress_offload entry for Hi-Res output.)
