Multimedia AppletsCD Player AppletCD Player Applet, shown in Figure 42, allows you to play CD's from a Panel. To add this applet to a Panel, right-click on the Panel and choose Panel->Add to panel->Applet->Multimedia->CD Player. UsageThis applet is used to unobtrusively play and control CD's while you get real work done or play FreeCell. To use it, just press the small buttons in the applet like you would on any CD player. Right-clicking on the applet brings up a menu containing the following items:

Mixer AppletMixer applet, shown in Figure 43, provides a simple and convenient interface for controlling the sound volume and launching the Audio Mixer. To add this applet to a Panel, right-click on the Panel and choose Panel->Add to panel->Applet->Multimedia->Mixer. UsageTo adjust the volume, slide the volume bar up (louder) or down (quieter). To mute (or un-mute) the volume, press the speaker icon at the bottom of the applet. Right-clicking on the applet brings up a menu containing the following items:

Sound Monitor AppletSound Monitor applet, shown in its default theme (appearance) in Figure 44, is a sound volume display and an interface for controlling ESD (the Enlightened Sound Daemon) -- GNOME component responsible for sound output. To add this applet to a Panel, right-click on the Panel and choose Panel->Add to panel->Applet->Multimedia->Sound Monitor. Sound in GNOMEGNOME uses a special program, called ESD (the Enlightened Sound Daemon), as an intermediary between applications and sound card. ESD allows mixing sound from several applications, so that you can play a game and hear the sound effects while listening to an aduio CD. To hear any sound from GNOME applications, ESD must be running. Normally GNOME is configured so that ESD is started every time you login; if for some reason this is not so, click on the Main Menu button (the foot icon) and select Programs->Setting->Multimedia->Sound and make sure that the option Enable sound server startup is enabled, so that the next time you login, ESD will be started. You can also start or stop ESD using the Sound Monitor applet as described below. Non-GNOME applications usually are not aware of ESD and need full control of the audio card --- they can not share audio card with other applications. This means with such applications, you can either have sound from GNOME or sound from non-GNOME application, but not both. In many cases, this means that you have to temporarily stop ESD to get sound from non-GNOME applications (otherwise, you get error messages like Device /dev/dsp busy). UsageSound Monitor always displays the volume of sound being produced on your system graphically. You may control sound by turning ESD on or off by right-clicking on the applet and selecting Place Esound in standby or Resume Esound respectively, as described below. Right-clicking on the applet brings up a menu containing the following items:
CustomizationYou can customize Sound Monitor applet by right-clicking on it and choosing Properties…. This will open the Properties dialog (shown in Figure 45), which allows you to change various settings. The properties in the General tab are:
The properties in the Theme tab are:
The properties in the Advanced tab are:
After you have made all the changes you want, click on OK to apply the changes and close the Properties dialog. To cancel the changes and return to previous values, click the Cancel button. The Sound Monitor ManagerTo start the Sound Monitor Manager, right-click on the applet and choose Manager…. This will open the Sound Monitor - Manager dialog (shown in Figure 47), which allows you to view and modify various ESD settings. The Server tab displays the following information:
The properties in the Streams tab are:
The properties in the Samples tab are:
After you made all the choices you want, click on OK to make the changes and close the Properties dialog. To cancel the changes and return to previous values, click the Cancel button. The Esound Persistent Volume Daemon (ESDPVD)The Sound Monitor applet comes with a companion program called the Esound Persistent Volume Daemon (ESDPVD), which can run in the background and remembers the volume and balance of each stream that connects to the sound server. The main purpose of ESDPVD is to be used in conjunction with the Sound Monitor applet's Manager dialog to retain volume levels for individual streams that connect to the ESD sound server. As an example, suppose you are running the GTCD CD Player and you lower its volume using the Manager window. Normally the volume setting will be lost when the program (in this case GTCD) is exited and restarted. However, if esdpvd is running and you start GTCD again, the volume will be restored to its previous (in this case, lower) value from before. If you configure GNOME to start ESDPVD each time GNOME is started (using the control-center's Startup Programs section), ESDPVD will remember sound volume and balance customizations between GNOME sessions. ESDPVD also remembers volume and balance adjustments to cached samples (often used for interface sound events such as button clicks, menus, etc.). Known Bugs and LimitationsThis applet only shows the sound volume for sound produced by GNOME applications (to be precise, sounds passing through ESD); it will not show sound volume for applications that directly connect to audio card.
