profiles: SeekBarVolumizer: Properly setup the minimum of the seekbar

Some streams, like the alarm stream, have a minimal volume of 1
instead of 0 which leads to a seekbar where 0 and 1 result in the
same volume set.

Test: The seekbar for a stream with a minimal value of 1 (alarm)
      starts with 1 and other streams stay uneffected
