No sound on Video Clips

[slowerhand]

I have a problem with my Dell PC running Windows 2000. Whenever I run Video clips I have picture but no sound. Both Real Player and Windows Media Player are installed on the PC.No errors messages are displayed and my Sound cards appears to function properly when playing Music CD's . Any ideas on this one please ?

If the only sound you can get is from audio CD's then:
-Check 'Device Manager/Sound, Video, and Game Controllers' for any IRQ conflicts or problems with missing or corrupt drivers, etc.
If an IRQ conflict exists, then manually assign a free IRQ to the sound card.
If there's a driver problem, then remove the sound card from Device Manager, restart the computer, reinstall the drivers.
-Go to Start/Settings/Control Panel/Multimedia/Audio, make sure the sound card is selected in the 'Preferred Device'
window under 'Playback', click the volume control icon next to the 'Preferred Device' window to adjust volume settings and make sure the Mute box is unchecked, click the Devices tab and click the + by 'Audio Devices' and make sure the circle is checked for 'Use Audio Features On This Device', and the box is unchecked for 'Do Not Map Thru This Device',
click the + next to 'Audio Codecs' and make sure there's a long list of codecs(MS, etc.).
-Make sure the volume control is properly adjusted in the sound card's software(if applicable).
-Reinstall Win MP and RP.
-If all of the above are ok, then the sound card may be bad. Try it on another system or try another card.

There is only 1 Audion Codec installed on the PC. Can you tell me please how do I go about installing additional Audio Codecs. Are there any particular codecs I should look out for ?

In Control Panel/Add-Remove Programs/Setup, click on the name Multimedia, then click on Details.
If the box for 'Audio Compression' is unchecked, then check it, insert your Windows installation CD, click OK, and restart your computer when prompted.
If the AC box is already checked, then uncheck it, click OK, restart, go back and check the box, and follow the above procedure.
