customizable audio device for volume control

hi... i have many audio devices....  i have special configuration that allows me to capture what i am listening, i use this configuration for video conferencing for example, for remote people could hear what i am playing (for showing videos for example)

so, my output device to my speakers IS NOT my default device... so when i point the system tray and move the mouse wheel i am not changing my playing volume but my recording volume.... i still hear low, but my conferencing partners blow their ears without me noticing

i would like an option to select the audio device when controling the volume with 7tt...  thanks for all
