The waveOutSetVolume function sets the volume level of the specified waveform-audio output device.

MMRESULT waveOutSetVolume(
DWORD dwVolume



Handle to an open waveform-audio output device. This parameter can also be a device identifier.


New volume setting. The low-order word contains the left-channel volume setting, and the high-order word contains the right-channel setting. A value of 0xFFFF represents full volume, and a value of 0x0000 is silence.

If a device does not support both left and right volume control, the low-order word of dwVolume specifies the volume level, and the high-order word is ignored.

bcraven did a great mixer control example available from this thread:

It sets the master volume but it can be used as a jumping off point for what you want to do.
