I've noticed problems when using Poweramp equalizer on my redmi phone to eq my Bluetooth earphone.
It seems that the advanced player tracking feature expires after a while, after which only players that can be recognized without dump permissions can be eq'd. eg. netease music.
If I reinstall Poweramp equlizer and re-grant dump permissions, it works again for a while, but eventually it stops working.
Note that the failure here is that Poweramp equalizer can no longer detect any non-player apps that play audio, such as bilibili.
even though the advanced player tracking apps (like bilibili) appear in the list of known players, but in reality eq is completely ineffective.
dragging and sliding preamp has no effect on the volume, restarting the player and switching the player switch on and off in kown players list doesn't help
however, when just granting advanced player tracking permissions. non-player apps can be detected, eq is fully valid and changing the equalizer has audible changes. Dragging preamp immediately has an effect on the volume of the certain app (bilibili)
The settings of Poweramp equalizer don't see anything unusual, it still says dump permission granted, notification permission granted, and player tracking is on.but it can't detect any non-player app that plays audio.
the device I'm using is redmi note 11t pro, miui version is miui 13.2.3, and Android version is Android 13.
