Audio Playback from the Remote Computer to the
Local Computer
Sending of microphone audio from the Local
Computer to the Remote Computer
1. The application-generated audio output.
2. If an audio device is installed, the application-generated
audio is routed through it.
3. If there is no audio device (such as with a blade
workstation), the HP Remote Audio virtual device is
automatically installed, and the application-generated
audio is routed to it.
4. Audio from either the audio device or the HP Remote
Audio virtual device is sent to the RGS Audio Recorder.
5. The RGS Audio Recorder captures the audio, which is
sent by RGS to the Local Computer.
6. The RGS Audio Player on the Local Computer decodes
the received audio, and sends it to the audio mixer.
7. The output of the audio mixer is sent to the Local
Computer audio device.
8. The audio device drives an audio output device, such as
a speaker.
USB devices are local:
1. The user selects the microphone source, either a USB
microphone or an analog microphone. The RGS Audio
Recorder captures the selected microphone source.
2. The audio captured by the RGS Audio Recorder is sent
by RGS to the RGS Audio Player on the Remote
Computer.
3. The RGS Audio Player decodes the audio signal, and
sends it to the HP Remote Microphone virtual device.
4. The HP Remote Microphone virtual device appears to the
application as a local microphone, and sends the
microphone audio to the application.
USB devices are Remote: Beginning at RGS 5.2.0,
certain USB microphones can be mounted to the Remote
Computer using the remote USB driver for the supported
microphones. See the previous section for a description of
Remote USB operation.
In RGS 5.4.8, the device the audio is recorded from can be specified in the RGS Sender property
Rgsender.Audio.Linux.DeviceName.
Run the command:
cat /proc/asound/devices
