Executable: (SDK Root)\Sample\Multimedia\DirectSound\Bin
Be sure your sound card is configured for full-duplex operation and that you have a microphone attached. Choose a format from the Output Format list. A list of formats appears in the Input Format list. Select one. Click OK. If full duplex is successfully created, another dialog box is displayed with a Record button. Click this button. Speak into the microphone and your voice is heard over the speakers.
