hI,

WaveOutSetVolume(hwo: Integer; dwVolume: Cardinal);

hwo is MediaPlayers DeviceId,

example:                          
dwVolume Full L+R = $FFFFFFFF
dwVolume Full L no R = $0000FFFF
dwVolume Full R no L = $FFFF0000
dwVolume 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.

so something like:
waveOutSetVolume(Mediaplayer1.DeviceID, $FFFF div 2);

should do it..
Regards Barry
