I use PowerAmp only and notification set to silent, if is some other not-silent show, PowerAmp is on oneline (with control), if not is on more lines.
If i now switch PowerAmp to not-silent show same on more line but in not-silent section…
Anyway i look into PowerAmp Settings/LookAndFeels/Notifications and have set “Notification Type” to “Media with custom cover”, if i set to “Auto” or “Media colorized” then is pinned ;-)
