Audio Playback from the Remote Computer to the Local
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.
Sending of microphone audio from the Local Computer to
the Remote Computer
USB devices are Local:
a. The user selects the microphone source, either a USB
microphone or an analog microphone. The RGS
Audio Recorder captures the selected microphone
source.
b. The audio captured by the RGS Audio Recorder is
sent by RGS to the RGS Audio Player on the Remote
Computer.
c. The RGS Audio Player decodes the audio signal, and
sends it to the HP Remote Microphone virtual device.
d. 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—see Appendix B
for the supported microphones. See the previous section
for a description of Remote USB operation.
