Remote Audio

Remote Audio allows audio generated by the sender to play back on the speakers of the receiver.

The following sequence describes the path taken by audio during an RGS connection:

1. Software on the sender generates audio output.

2. The audio output is routed to RGS Sender using a physical or virtual audio device.

3. RGS Sender encodes and transmits the audio output to RGS Receiver on each receiver.

4. RGS Receiver decodes and sends the audio output to the audio mixer of the operating system.

5. The audio mixer of the operating system sends the audio to the default audio playback device.

6. The audio device plays the audio output on a connected audio peripheral, such as a speaker.

NOTE: Sounds that play through an internal speaker, such as the ToggleKeys sound on Windows, are not

captured by RGS.

For information on the audio settings in RGS Receiver, see Audio on page 18.

For Remote Audio troubleshooting tips, see Troubleshooting Remote Audio on page 69.

Using Remote Audio (Windows)

On Windows, Remote Audio should work by default. If the sender has an audio device, the RGS Sender

installation process detects it. If the sender does not have an audio device (or if you disable all audio devices

prior to installation of RGS Sender), then the HP Remote Audio virtual audio device is also installed during

the RGS Sender installation process and will be used by RGS instead.

Using Remote Audio (Linux)

On Linux, some manual conguration might be required for Remote Audio depending on the audio capture

method you intend to use.

If the sender has an audio device, RGS supports two dierent methods of audio capture:

●

PulseAudio—See PulseAudio on page 37.

●

Advanced Linux Sound Architecture (ALSA)—See ALSA on page 38.

The following property species which audio capture method will be used (see Global properties that can be

set manually only on page 60 for more information):

Rgsender.Audio.Linux.RecorderApi

NOTE: Some audio device drivers might not have the capability to capture application-generated audio.

If the sender does not have an audio device, see Virtual audio driver on page 39.

PulseAudio

Any audio device that is congured for PulseAudio can be used. PulseAudio provides a software interface

similar to the Stereo Mix capability for ALSA. PulseAudio also provides a dummy device that allows the audio

system to function when no hardware audio devices are available.

When using PulseAudio to capture audio, RGS Sender attempts to detect and connect to the default capture

device of the sender automatically. Explicit control of the PulseAudio capture device is available through the

following property (see Global properties that can be set manually only on page 60 for more information):
