Modify how Playtones() is used in Milliwatt() to resolve gain issue.

When Milliwatt() was changed internally to use Playtones() so that the proper
tone was used, it introduced a drop in gain in the output signal.  So, use
the playtones API directly and specify a volume argument such that the output
matches the gain of the original Milliwatt() code.
