Keyboard - Host-N (By default, Host is the right Ctrl key.)

Command - Use the -i or --clientid command option of the ovdc command.

Hotdesking from a Sun Ray Client to another Sun Ray Client with a different monitor configuration, monitor resolution, or monitor orientation.

Hotdesking from a Sun Ray Client to an Oracle Virtual Desktop Client running on a client computer, and vice versa.

Resizing the window while running Oracle Virtual Desktop Client in window mode. The session's display automatically resizes to the new window size. If you reduce the size of a window without desktop session resizing, you must use scroll bars to view the entire display, because the session's display does not automatically resize and is too big to fit in the smaller window.

Rotating a tablet from landscape to portrait mode while running the Oracle Virtual Desktop Client application, and vice versa. The remote desktop automatically rotates with the tablet.

Use the Oracle keyboard audio keys and check the volume and mute buttons.

Display the Sun Ray session's audio settings:

$ utsettings

and verify that the audio output is selected properly, for example, for headphones or speakers.

Make sure the volume is not muted in your desktop session.

Try a set of external speakers plugged into the Sun Ray Client's audio out or headphones port. If that works, the Sun Ray Client might have a broken speaker.

To test whether the audio is working, type the following:

$ cat audiofile > $AUDIODEV

Oracle Solaris provides suitable sample PCM-encoded audio files in /usr/share/audio/samples/au, so for instance this command:

$ cat /usr/share/audio/samples/au/gong.au > $AUDIODEV

should produce the sound of a gong.

Linux generally does not provide PCM-encoded audio files. If you can not locate a suitable file then this command can be used to generate a continuous tone:

$ perl -e 'foreach(-8..8){push(@v,pack("n",4*$_))} while(1){print @v}' > $AUDIODEV

If the cat or perl command hangs, you might need to quit any other applications that are currently trying to play audio, for example, a browser.

Check the current release of the Flash plugin and make sure it is at version 9.0.r125 or later. To check the Flash plugin version, type about:plugins as the URL in the browser.

Try quitting Firefox and explicitly restart it in a terminal window.

If all else fails, quit Firefox, go to your .mozilla directory, and rename the "firefox" directory to something else, for example, firefox.jan09. Then, restart Firefox and see whether the audio works with a completely clean configuration.

If the audio works with the clean configuration, then something is wrong in your browser's previous configuration.

To optimize the shared memory used by PulseAudio, add the following line to the /etc/pulse/client.conf file on the Sun Ray server:

shm-size-bytes = 131072

When using Oracle Solaris 11, the Oracle Solaris 10 SADA audio interface is automatically available if needed for compatibility reasons. An additional SADA-specific utaudio process is started for each session. See Section 13.1.7, “Audio Output Troubleshooting (Oracle Solaris 10 and Oracle Linux 5)” for more details.

For Oracle Solaris 11, the Adobe Flash Player is a SADA application that uses the $AUDIODEV interface. A device lockout may occur if multiple SADA applications share the same $AUDIODEV. To fix this problem, launch a separate utaudio command for each SADA application.

For Oracle Solaris 11 Trusted Extensions, two audio devices should be displayed in the Device Allocation Manager, one for the SADA interface device and another one for PulseAudio. Make sure to allocate both audio devices.

Use the Oracle keyboard audio keys and check the volume and mute buttons.

Display the Sun Ray session's audio settings:

$ utsettings

and verify that the audio output is selected properly, for example, for headphones or speakers.

Make sure the volume is not muted in your desktop session.

Try a set of external speakers plugged into the Sun Ray Client's audio out or headphones port. If that works, the Sun Ray Client might have a broken speaker.

Make sure the pulseaudio process is running. If it was not started with the user session, remove the $HOME/.pulse directory, exit the session, and start a session again.

Make sure there is a utaudio process running with the -p option to accept streaming from the PulseAudio sound server. If the process does not exist, check the /var/opt/SUNWut/log/messages log file to see if there is any error message from the pulseaudio or utaudio command.

If audio does not work when using GStreamer-based programs, such as Totem or Rhythmbox, make sure GStreamer is configured to use PulseAudio by running gstreamer-properties. The PulseAudio Sound Server setting must be selected for both Audio Input and Output.

For Oracle Linux 6, make sure ALSA is configured to use PulseAudio. To verify the configuration, make sure the /etc/asound.conf ( server preference) or $HOME/.asoundrc file (user preference) includes the following:

pcm.pulse {
     type pulse
}
ctl.pulse {
     type pulse
}
pcm.!default {
     type pulse
}
ctl.!default {
     type pulse
}      

If both files exist, the $HOME/.asoundrc file takes precedence.

If audio does not work with OSS applications on Oracle Linux 6, make sure the $AUDIODEV environment variable is set to an instance of utaudio. For Oracle Linux 6, the $AUDIODEV environment variable is not defined by default. Here is an example of setting $AUDIODEV:

$ export AUDIODEV=`/opt/SUNWut/bin/utaudio`

OSS applications on Oracle Linux 6 can also work with PulseAudio by using the OSS wrapper (padsp):.

$ padsp OSS_program
