Poweramp Build: build-899arm4-play [899004-6b777921]
So some additional notes: when I boot the phone, if I open Poweramp immediately, I get 24/32 bit 384khz depending on the connected device. However, if I put the screen to sleep or disconnect and reconnect the device, it goes back down to 16/48 and sits there. I can upload a log if necessary. When hi-res output is playing, I was able to run adb shell dumpsys media.audio_flinger and have also attached that output. If it is helpful, I have a screen recording of the failure as it happens and will be more than happy to help troubleshoot further. Thanks to the team for all your hard work!
