I'm on Huawei Honor 8 and I also hear similar noises on low volume passages. An example would be John Preston's soundtrack to the maze runner, specifically the first 10 seconds of the Finale track.
What's strange is with the stock music player the noise isn't there. I have actually tried other players and even bass boosting apps, all of them has a similar noise issue so long as any sort of Eq is active.
On the Honor 8 you can only output to 48khz since that's what the audio configuration exposes, even though on paper the same dac is used in Mate 8 and P9 as well and that was listed as 24/96
I suspect it's to do with resampling, as dither settings help alleviate some of it, but not all.
The issue is present regardless of whether dts headphone system setting is turned on.
If I increase play back volume then the noise becomes more of an uniform floor and less like distortion in the characteristics of the rising violin. It almost sounds like the resampling happens post digital volume reduction, which is really terrible if true (really like 3 bits worth of dynamic range?). I'm not sure if this is an android issue in general, though it happens on marshmallow and nougat beta.
I was hoping to get high res support to custom output at 44.1khz instead and see if that works. Still, it's a bit a mystery to me why the stock player works if it does resampling.
