Any bass boost on the app distorts the bass on Pixel 9

Title. It's happening even on AIDL mode. I tried setting preamp, different headphones, changing eq presets.

It seems the program's algorithm normalizes the output audio based on the average of the minimum and maximum correction levels. Values ​​above zero dB appear, causing distortion. Ideally, the maximum correction values ​​should be equal to or below zero dB. I've noticed this in my own corrections. I suspect the same applies to other effects.
Adjusting the channel balance to -9.9 dB, for example, fixes the issue.

Setting channel balance to -9.9 dB doesn't work for me.

Automatic post gain in the limiter options should fix distortion. It's similar to setting pre amp.

It's more like, when having this auto post gain enabled, the distortion actually disappears, but whenever the bass hits, the volume gets really turned down.

Can you share the exact settings you have applied so I can reproduce the issue? And which headphones and music player do you use? Please also share a test song.

I use SPC Gear Viro Plus headphones with breathable earpads. They're connected to the phone via cx31993 + max97220 dongle. Usually I use Spotify but the problem appears on other music apps too.
Test songs:

1. JPEGMAFIA - ''NEMO - OFFLINE''
2. Charli xcx - ''365 featuring shygirl''

I've noticed that this is also happening on my bluetooth headphones Xiaomi Buds 3.
