I have used the app before on many other phones without issue, however I am not able to get it working on my current device. I am using a Lenovo ZUK Z2 Plus with LineageOS 18.1 custom ROM based on Android 11.
I have installed the app and enabled the advanced player tracking switch, with both DUMP permission and notification listener permission granted. All of my audio player apps (Spotify, YouTube, etc) appear in the "Known Players" section with the switches enabled. When I play audio from these apps it shows "Time last seen: 0 minutes ago"
Despite this, there is no sound processed by Poweramp EQ. The name of the current player does not appear above the bass/treble knobs on the homescreen and there is no sound visualisation even though Poweramp EQ has permissions for full microphone access.
Can anyone figure out what could be causing this issue? I have attached some screenshots that I hope will be of assistance. The stock AudioFX equaliser that comes with Lineage has been switched off and disabled via ADB.
