No modern PC can and should do without sound. Windows XP as well as a lot of applications use sounds to give feedback to the user, or to signal an event happening. And when you play an MP3 file or watch some video, you definitely want to hear sound from your speakers or headset. Another typical area where sound problems can come up is while making voice calls over the internet. Skype, AI, MSN, Yahoo, GoogleTalk, the all are very suited for voice calls.
When you are facing audio problems, a structured way of finding the cause can be helpful. We will skip the steps where you check if everything is plugged properly, since that should always be the case. If your audio card uses jack sensing technology, make sure you select the proper device when asked about it (when plugging devices). Follow the green = speakers, pink = microphone and things should be okay.
Steps to Fix Sound Problems
* If you have an onboard audio card, you need to make sure the onboard audio device is enabled in the Bios. Instruction will vary per motherboard, so you need to follow the instructions in your PC or motherboard manual for this. If you are using a separate sound card, the onboard should be disabled of course!
* In Windows XP, open the Device Manager (open the Control Panel -> double-click the System icon -> in System Properties dialog box, select Hardware tab -> click Device Manager button).
* In the Device Manager, open the “Sound, video and game controllers” group. Here you should see your audio device as shown in the image.

* If the sound device is not listed, check if any devices are listed in the “Other devices” or “Unknown devices” group, most likely with a yellow exclamation mark.
* If the device is not listed or if devices are listed under the “Unknown devices” group, the most likely cause is a missing or incorrect device driver. If you have the sound driver for the sound device, (re)install the sound drivers. If you do not have the drivers the easiest method is to use a driver update tool.
* If updating the drivers does not work, you need to find the cause of the problematic device.
* If the sound device is listed in the Device Manager, and you still do not have sound, first open the Control Panel.
* In the Control Panel, double-click “Sounds and Audio Devices”.
* In the first screen, with the Volume tab active, make sure the Mute checkbox is not selected and that the volume slider is close to High.

* Next, click the Advanced button, and in the Advanced Audio Properties dialog box, make sure you have a valid Speaker setup. At least make sure it is not set to “No speakers”. Click OK when done.

* Now click the Speaker Volume button. Both the Left and Right speaker volume should be close to High. Click OK when done.

* Next, select the Audio tab in the Sounds and Audio Devices Properties dialog box.
* In the Sound playback group, you want to set the Default device to your sound card device. Part of the name will normally match with the name you found in the device manager.

Also click the Volume button in the Sound playback group and adjust the Volumes to a high enough level. The Volume Control will show the mixer, which does depend on the audio device installed. The sample has a SoundMax audio card. Clear all the Mute checkboxes.

* You can repeat these steps for the MIDI music playback.
* Although not a frequent problem, check if the Audio Service is running:
o Select Administrative Tools in the Control Panel.
o Then double-click Component Services, which will open a separate window.
o In the left-hand pane, click Services (Local).
o In the right-hand pane, scroll down to the Windows Audio service and make sure it is not disabled. If necessary, right-click Windows Audio, in the popup menu select Properties and then set the startup type to Automatic.
* If you have sound problems in games, you can check the sound card resources. Especially older games have limited detection of sound cards in respect to resources (IRQ, I/O address range).
Test Sound with an Application
With these steps, you have checked and adjusted the sound setup in Windows XP. If sound problems still persist, chances are there are problems with the sound settings in the application you are using. If the sound problems are present for all applications, there probably is something wrong with the hardware.
The best application to test your sound setup with is the Windows Media Player, as it will use the standard Windows sound setup, which you just verified and adjusted.
One setting in the Windows Media Player that needs to be verified is the DirectSound device.
* Open the Windows Media Player.
* In the Media Player, select Options in the Tools menu (press the Alt key to show the menu if not visible).
* In the Options dialog box, select the Devices tab.
Windows Media Player Options
* Now select the Speakers device and click the Properties button.
* In the Speaker Properties dialog box, select the audio device to use for Sound playback. By default it will have Default DirectSound Device selected, but you can change it to the DirectSound device that is listed for your audio device.

Also clear the Use 24-bit audio for audio CDs for now to make sure that this Performance setting is not causing any problems.
* Click OK to close the Speaker Properties and then click OK again to close the Options dialog box.
For testing purposes, use an audio file that was installed with Windows XP. These audio samples are standard audio files, which do not require any additional or special audio codes.
Other applications that use sound will normally have a similar option to change the sound device selection and volume. For games, the sound setup is particularly sensitive. The right and latest device driver is often required.
Audio and Video Codecs
When a computer plays an audio or video file, it will decode the audio or video data to be played with the sound device. Each different audio and video format requires its own decoder, or codec. One of the possible problems with no sound is that the right audio codec or video codec is not installed.
If your standard audio files do play, but a certain MP3, AVI or WMV file does not produce audio, the first thing to try is to install missing codecs. You can try and find out which codec is required and then find and install that code, but luckily there are a number of codec packages that can be downloaded and installed.
One of the most used codec packages is the K-Lite Codec Pack. With that installed most audio and video should play without problems … and with sound. There are more of course, a quick internet search can help you find others.
Find Out Which Sound Card Is Installed
Knowing exactly what type of sound card is installed in your computer can be of great help in looking for solutions to sound problems. It can help you find the right sound driver, look up software and maybe help search the internet for more targetted problem descriptions based on manufacturer and model.
One handy way of finding out which sound card is installed is to use a program like Belarc Advisor. It will analyze your system and tell you about your hardware and software.
