Solution 1: Check that your system volume is not muted or set too low.
To adjust your system volume levels, you will need to access the speaker icon on your taskbar. If you do not see the speaker icon on your taskbar, please read
RealPlayer plays sound using the Wave Out controls of your sound card. If the Volume Control sliders are muted, RealPlayer will not play sound.
To make sure the volume is not muted on your system:
1. Double-click the speaker icon next to the clock in the lower right corner of your screen.
2. In the Volume Control dialog box, make sure that all of the Mute boxes are clear.
If the Volume Control dialog box does not display the Volume Control or Wave sliders, add them:
1. Double-click the speaker icon, select the Options menu, and choose Properties.
2. In the Show the following controls section, select Volume Control and Wave.
3. Click OK.
Solution 2: Determine if the problem is with the specific file.
To rule out a problem with the file itself, try playing the sample file provided with RealPlayer:
1. From the Windows Start button, select Search (Find), and then For Files and Folders.
2. Type videotest.rm and click Search.
3. Double-click the videotest.rm file.
If you can hear the audio of the sample file, then the problem may be with the specific file you were trying to play.
Solution 3: Check the connection of the CD-ROM audio cable to the sound card.
If the file you are trying to play is from a CD, the CD audio cable that runs from the CD-ROM drive to the sound card may be missing or damaged.
To check the cable connection:
1. Plug a headphone set directly into the CD-ROM audio jack (usually next to the CD-ROM drive).
Note: If you do not have a headphone set, unplug your speakers from your sound card, and then plug them directly into the CD-ROM audio jack. Make a note of where they are currently plugged in so that you can easily replace them when you are done.
2. Play a song from the CD.
If you can hear the music, this means that the CD-ROM audio cable is not connected to the sound card. Contact your computer or CD-ROM manufacturer for help with connecting the CD-ROM audio cable to the sound card.
If you cannot hear the music, continue to try other solutions.
Solution 4: Close other programs that might be using the sound card.
