+ DietPi-Set_hardware | soundcard: Fix amixer controls loop when generic USB DAC is selected, which did split at spaces within the control name. Use the unique numid (first field) as identifier. Outstanding test: Set "100%" for controls which do not take percentage values or are actually no volumes, like "Playback switch".
