Not true. SoundVolume only affects the specified sound (as do the other Sound~ commands).
Oh, well then perhaps you could explain this straight from the docs: ChannelVolume channel_handle, volume#
Parameters
channel_handle = variable assigned to the channel when played
volume# = volume level floating value between 0 and 1
Description
While SoundVolume happily changes the volume of the entire program, this command will let you adjust volume rates on a 'per channel' basis. Extremely useful.
The volume value is a floating point value between 0 and 1 (0 = silence, .5 = half volume, 1= full volume). You can do other cool stuff like ChannelPitch and ChannelPan too!
