(info) In addition to providing an emulated sound card to the Solaris guest operating system, the audio configuration also enables the Keyboard Buzz feature, i.e., it allows Solaris applications to create keyboard beeps.

Prerequisites:

On the Linux audio server, PulseAudio must be enabled for network access. Perform the following steps to enable network access to PulseAudio on the Linux audio server:

Configure PulseAudio on Linux for network access

StepDescriptionCommand
1

Check if PulseAudio is installed on the system.

# rpm -qa | grep -i pulseaudio

If the software is not installed, use

# yum install pulseaudio pulseaudio-utils

to install it.

2

Enable network access to the PulseAudio server.

Edit the PulseAudio configuration file:

If PulseAudio runs under the non-root account of the current desktop user (normal case, recommended):

# vi /etc/pulse/default.pa

If PulseAudio is run as root user (system mode, not recommended, only useful in special cases – e.g., embedded use where no real local users exist):

# vi /etc/pulse/system.pa

Add the following line if it does not already exist:

load-module module-native-protocol-tcp auth-anonymous=1

Save the file.

3

Restart the PulseAudio server.

If the default.pa file was modified, the following commands must be run as the non-root user under which PulseAudio was originally started.

Stop the PulseAudio server:

$ pulseaudio -k

Start the PulseAudio server:

$ pulseaudio --start

If PulseAudio was started in system mode and the system.pa file was modified, the system-wide service must be restarted.

Please note: if “autospawn = yes” is set in /etc/pulse/client.conf, the process will be restarted automatically after stopping it.

4

Check if the server is listening on its port.

# netstat -an | grep 4713

OR

# netstat -a | grep -i pulse

(warning)  Make sure access to the PulseAudio server port is not blocked by a firewall. However, access to the port should only be allowed as required in order to minimize security risks.

...

After configuring the audio function and rebooting the Solaris guest system, use the command-line utilities audioplay/audiorecord, the GUI-based Java media player, sdtaudio, or audiotool depending on the Solaris version used. These tools allow you to record and play back audio.
