v7.1

+ DietPi-Software | soundcard: Remove setting controls on Sparky SBC generic USB DAC selection. Those with "playback" in their name are not necessarily volume controls and do not necessarily accept percentage values. Also multiple outputs might be available which shall not necessarily have 100% volume. Since that feature was falsely implemented before, but no user did complain, effectively nothing changes, but obsolete failing command calls are removed.
