HTC 10 everything stock

Hi-Res output somewhat works, but occasionally crashes when changing songs or when I pause the song and play it back immediately.
Also there is big output latency (1687ms) when using wired headphones!
The seconds in the "now playing" bar are unsynchronized and they skip. Sometimes when I start a song, it doesn't start from the beginning (0:00), it starts from 0:03 or similar.
There's a bug in audio management: for Android, audio is recognised as casted from an external device, and not directly from smartphone.
I hope the next Poweramp build will fully support Hi-Res output on HTC 10, currently one of the best phones when it comes to audio.
