My Question or Issue

When streaming music with Samsung S10+  connected to a JBL Boombox, when increasing volume on phone there's too  large of increases in the volume...   Between one click and the next it's the difference between being too loud for normal listening  and  barely hearing  it  on the other extreme...   That's all in one single  adjustment of the volume buttons on side of the mobile device!
