After you have selected the mixer, the Sender should record audio information and send it to the Receiver. Refer to the Windows RGS Sender Audio Calibration section to improve the audio quality. If you are not getting an audio signal, refer to the Windows Audio Troubleshooting section.
Calibrating Audio on a Sender for WindowsThe audio signal captured by the sender is modified by two different device driver volume controls and then the master volume level is artificially inserted into the signal. If these volume controls are too low, you might hear the audio signal. If they are too high, the signal may be distorted. This section describes a technique to hand tune the controls to reduce the amount of distortion. These operations should be performed while connected to the sender through the receiver.
The Wave line of the Volume Control is the first volume control to impact the audio signal outside of the application that generates the signal. Setting this value to the maximum level gives you the most resolution in your audio signal. The following image shows an example of this control at its maximum level.
