Soundplay volume on Macs

[joshwalawender]

Some info on sound from Brad Holden is below. Putting it here for reference.

The sound player for the Mac, afplay, wants a value for the volume between 0 and 1. Eventsounds gives a value between 0 and 100, so even a volume of 1 is maximum. Setting the -pv option on sound play lets you re-scale the output value of afplay. A value of 0.01 for Macs is recommended.

I do not edit the config.

I have a horrible line in soundplay.py that says basically

if  'macosx' in  soundplayer:
   cmd.append('-pv')
   cmd.append('0.01')

I am hoping to get Will to remake soundplay for the Mac so that this scaling becomes the default.
