Revert "CompoundButton: Let text can be changed by config"

This reverts commit 8143b266ff7e26d6e2a2ebced228d300bc9f53d4.
Increase available volume levels

Increase media volume levels from 15 to 30 to have more precise
volume control instead of having only 15 levels from 0-100%

For example, when listening to music it is often the case that one
volume level is too quiet and the next one higher is too loud (especially with Headsets).
