system volume

hi all,

What i would like to do is to be able to change the system volume for all outputs (mp3, video etc) and be able to do this while a sound is playing. Does anyone have any ideas, or can point me in the right direction.

Many thanks

To change system setting you mostly need an API call, probably one of the following:

or

hope this helps,
Rick
