well for tmediaplayer you can do stuff like:

WaveOutSetVolume(hwo: Integer; dwVolume: Cardinal);

hwo is MediaPlayer1.DeviceId,

example:                           Right\/ | Left\/
dwVolume for Full L+R = $FFFFFFFF
dwVolume for Full L no R = $0000FFFF
dwVolume for Full R no L = $FFFF0000
dwVolume for no sound = $00000000

notice that the hi-order word refers to right channel and
lo-order word to left channel...
If use to set a mono soundcard, u specify the lo-order word
only.

WaveOutGetVolume retrieves the volume settings.
