GNOME Audio for UD Sun Ray Terminals

The Sun Ray terminals have sound capability and a built-in speaker. There are two levels of sound control. The GNOME sound control is near the upper-right corner of the top panel. The lower-level sound control is done with the keys near the upper-right corner of the keyboard. Make sure the speaker is not muted and the volume for both controls is up.

In a lab setting, please bring a headphone set to plug into the Sun Ray terminal. If you do not get sound from your headphones, see Troubleshooting in the GNOME Desktop document.

Playing an audio file from a Nautilus window

You can recognize an audio file by the icon used in the Nautilus window:

MP3 Audio Dolby Digital audio MIDI audio Sun mu-law audio Wave audio RealAudio Apple audio format

There are several ways to play an audio file:

  • Double-click on the audio file.
  • Right-click on the audio file and select an option in the Open With menu.
  • Launch an audio player and open the file from the application.
  • Drag the audio file and drop it into an audio player on the desktop.

With the following hints, this should be straightforward for those familiar with a windowing system.

  • If the audio file is in your home directory, open a Nautilus window to your home directory by using Applications > Home Folder.
  • If the audio file is on a USB flash drive, open a Nautilus window for your USB flash drive using Applications > System Tools > mount USB mass storage device.
  • The audio players "Media Player" and "Sound Recorder" are both available from the Applications > Sound & Video pull-down menu.
  • To put an audio player on the desktop, drag one of these applications from the pull-down menu to the desktop. It can then be used as a drag-and-drop spot on the desktop.

Playing an Audio File in Firefox

Bird sounds

The Firefox web browser can also play audio files, but it needs to be configured. Middle-click on the Bird sounds link on this page. If your Firefox browser has never encountered a WAV file, it will ask you what to do with the file using a dialog box similar to the one shown below. If you see a Browse.. button displayed after Open with, then Firefox has no recommendation for this type of file. Click the diamond next to Open with and click the Browse button.
