Configuring audio on Microsoft Windows Vista and Windows 7
Sender
When a connection is established between a Receiver and Sender, an audio session is created on the
Sender. When audio is enabled in the Receiver GUI, audio will be captured from the default playback
device. The master volume level on the Sender should have the expected impact on the remote audio
volume level. Windows Vista and Windows 7 also allow application specific volume controls through
the Volume Mixer. This can be opened through the volume control in the taskbar. This control will allow
the Sender volume to be adjusted relative to the master volume as shown in
Figure 6-12 Volume Mixer
for Windows Vista and Windows 7 on page 122

Configuring audio on Linux
The audio devices on Linux are not consistent in the naming conventions of the audio controls. The RGS
Sender installer will attempt to adjust volume levels for known audio devices to allow audio to be
captured. See Linux remote audio device support on page 230 for a list of supported audio devices.
This section describes how to adjust volume levels for the supported audio devices. This information
may be helpful for configuring audio devices that are not currently supported by the RGS Sender
installer.
Volume levels can typically be adjusted through the Volume Control application. This is usually found in
the gnome panel or the system preferences menu. The Volume Control application may not show all
available volume controls. The preferences for the Volume Control application may need to be adjusted
to allow access to hidden volume controls.
The alsamixer is a command line program for adjusting volume. This application won't hide audio
controls like its GUI counterpart, however it is not as intuitive. Press the h key after running alsamixer to
get additional information on how to control capture volumes.
