Sound Problem

When I am trying to play an MP3 via Real Jukebox - I am getting an error message "Can not open the audio device.  Another application may be using it."  But I don't think there's anything else using sound.  Some sound is working through my speakers in that if I make a modem call - you can hear the modems handshaking through the external speakers.  Help please.
Who is Participating?
Why do I receive the error message "Cannot Open Audio Device" when starting RealJukebox 2.0 and earlier versions?
RealJukebox 2.0 and earlier use the sound card to record and playback media files. If the sound card is in use by another program, or if RealJukebox cannot detect the sound card, the following message will appear:

"Cannot Open Audio Device. Another application may be using it."

To correct this problem, do one or more of the following:

Solution 1
Close unnecessary programs.

Use the following directions to close all unnecessary programs in the "Close Programs" list, then try running RealJukebox.

1. On the keyboard, hold down CTRL and ALT keys, and press the DEL key once.
2. In the Close Programs dialog box, select the first program in the list and click the End Task button.
3. Once the dialog box disappears, press CTRL+ALT+DEL again.
4. Keep repeating steps 1-3 until all entries except Explorer are gone.
5. Start RealJukebox.

Note: Do not "End Task" on the Explorer or SysTray items.

Solution 2
Restart Windows.

1. Exit all programs.
2. Click the Start button, choose Shut Down, and then Restart the Computer.

After Windows has restarted, start RealJukebox before any other programs.

Solution 3
Enable the full-duplex feature on the sound card.

In order to use the "Playback while Record" feature in RealJukebox, you must enable the full-duplex feature your sound card.

To enable full-duplex operation on your sound card, do the following:

1. Click the Start button, choose Settings, and then Control Panel.
2. Double-click the System icon.
3. Click the Device Manager tab.
4. Click the plus (+) sign next to the "Sound, video and game controllers" category.
5. Find the entry under the "Sound, video and game controllers" category for your sound card.
6. Select your sound card and click Properties.
7. Select the Settings tab.
8. Look for a check box that is labeled "Allow Full-Duplex operation" and select it. If the check box is labeled "Disable Full-Duplex operation", deselect it.
9. Click OK.
10. Restart Windows.

If you cannot locate the full-duplex option, or you need further assistance configuring your sound card, please contact the manufacturer of your sound card or computer system.

You may also receive errors when playing a mono formatted file while simultaneously recording a track in Analog recording mode. Analog recording mode requires more system resources. To prevent errors while recording in Analog mode, please do not play files while recording.

Solution 4
Update the sound card driver.

A sound card driver is a small piece of software that allows the computer to communicate with, and control, the sound card inside the computer. Most soundcard manufacturers typically release a new driver several times a year. Downloading and installing a new driver for your sound card can enhance the performance of your sound card and eliminate driver corruption or software incompatibilities.

Sound card driver updates are usually available free from the manufacturer's web site. Please refer to your sound card or computer manuals for further contact information. We also recommend that you refer to the technical support contact provided by the sound card manufacturer for more detailed download and install instructions.

If you continue to have audio device problems after performing these steps, please contact RealNetworks Technical Support.
