Description: This program is equivalent to the "Mute all" check box of Windows Volume Control for Playback. The Master Mute control is the MIXERCONTROL_CONTROLTYPE_MUTE control of the MIXERLINE_COMPONENTTYPE_DST_SPEAKERS destination audio line. It belongs to the switch controls (MIXERCONTROL_CT_CLASS_SWITCH), which are two-state switches. It uses the MIXERCONTROLDETAILS_BOOLEAN structure to retrieve and set control properties. Whenever the check box is clicked, CMuteDlg::amdSetMasterMuteValue() is called to set the Master Mute value accordingly. The MM_MIXM_CONTROL_CHANGE message is received once the state of the Master Mute control has changed. In this case, CMuteDlg::amdGetMasterMuteValue() is called to retrieve the current value of the Master Mute control and update the state of the check box accordingly.
