Remote Audio on Linux
The following table describes the paths taken by both application-generated audio output and
microphone audio on Linux.
Table 8-2 Linux RGS audio data paths
Audio playback from the remote computer to the local
computer
Sending of microphone audio from the local computer to the
remote computer
1. An application on the remote computer generates audio
output.
2. If an audio device is installed, the application-generated
audio is routed through it.
3. If there is no audio device, the application-generated
audio is routed through the Virtual Audio Driver.
4. Audio from either the audio device or the Virtual Audio
Driver 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 Remote or Local/Remote: Certain USB
microphones can be attached to the remote computer using
the Remote USB functionality. The remote computer must be
running Windows.
NOTE: For more information, see
Remoting USB
microphones on page 52.
USB devices are Local: RGS on Linux does not support
locally-mounted USB microphones.
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
From this, you will see a list of the audio devices and it will look something like this:
0: [ 0] : control
1: : sequencer
8: [ 0- 0]: raw midi
16: [ 0- 0]: digital audio playbac
17: [ 0- 1]: digital audio playback
24: [ 0- 0]: digital audio capture
32: [ 1] : control
