Anonymous from May 13 again. Just worked out how it was working for me. It's on by default in the LineageOS custom rom (the setting is called "Control playback" if you search your settings for those running the ROM and it has a description under it of "Seek music tracks by long pressing the volume keys while the display is off"). Has been there since LineageOS 15.x at least (https://forum.fairphone.com/t/lineageos-15-1-settings-reference-wiki/41954). I find it hard to listen to podcasts with the screen off without the feature.
