Actually wizmo can set both the volume for the wave device and the overall volume:
volume={0-100} — set the system's audio level
If you enjoy associating sounds with system events, you probably grow accustomed to the sounds being at a certain volume level. So, when you need to turn that volume up or down when playing a video clip, or being away from your machine, it is convenient to be able to return the volume to its original level. Wizmo's "volume=" command easily sets the system's volume to a percentage of full volume. Another use for this is creating simple script programs. The example below demonstrates a simple script to turn the volume up while the screen saver is active, then back down after blanking is cancelled.
Exemple: wizmo volume=90 monoff volume=20
wave={0-100} — set the system's wave file audio level
The system's wave file playback level can be controlled independently from the overall sound level. The "wave=" command allows this to be independently set.
Example: wizmo wave=25
