Volume control scale has an odd jump

The volume control jumps a lot from third step to fourth step (if I remember the steps correctly).

This is an annoying problem with louder BT-speakers like the JBL Charge 5. When one step is way too loud and the one down from that is way too quiet.

Does anyone know if there are any settings or workarounds to re-scale the volume somehow?

The JBL sadly doesn’t appear to have it’s own volume control.
