[Bug?] DSP massivly oversteering bass with Oreo

[r00f]

My phone got an update to oreo (Honor 9).
Since then my equalizer did not change but everything is oversteering especially the frequences below 500Hz.
There have not been any chaning in equalizer or audio hardware or anything else.

Using latest update 2.02 i think.
Phone is Honor 9 and as headphones I use NuForce HEM 2.

Is there anything known about?
