For over 1 year I have this bug with Poweramp v3, currently running 906-911. (LE: actually from the moment v3 was in alpha and wasn't available in playstore, but I was too lazy to report it)
Ecountered it on 2 devices: Samsung Note 2 (GT-N7100) runnning multiple custom roms and Huawei Mate 10 Pro (BLA-L29) stock from android 8 to 10.
I listen to music with Equ and Tone enabled, but everytime I lower the volume even one step, it sounds horrible, music starts to rattle. I can describe it sounds like broken speakers. Setting the volume back to max fixes it. The only way to listen at lower volumes is to disable Equ and Tone (Limit is always on).
I tried all the possible settings, nothing seems to work, tried all output plugins, different buffers, etc. It does the same on phone's speaker, bluetooth, cable, everything.
