Why does sound work with Media Player but not with IE or system sounds?

By bamac86 ·
Dell Inspiron 6000 ( years old)
OS: Win XP Media Center
Sound: SigmaTel C-Major Audio

Nothing was working, no sound at all... so I went into Dev. Mgr. and disabled and then re-enabled the sound card. This caused the sound to begin working with Media Player, but it will not work with anything else, such as system sounds or YouTube on the web, etc.

Things I have tried: I have gone into the Advanced Sound settings to make sure nothing is set to mute. I checked the driver, but it tells me I have the most current driver installed. (Side note: I just had my LCD screen replaced as the old one was going black on me. Once I received the computer back, I also tried to clean it up a bit by uninstalling some unused programs, running the defragmenter, and purging the temporary files. Could this have affected the sound?)

Any thoughts about a fix would be greatly appreciated!

Tried but didn't work

by bamac86 In reply to Check this link

Thanks Jacky. I tried loading the regedit list but to no avail. Nothing happened... still no sound with system, only within WMP do I get sound. I cannot control volume or anything else except through the onboard icons within WMP.

I discovered tonight while going through my Device Mgr. that my system speakers have "no driver currently installed." When I tried to let it search for a driver it found none. Could this be the problem, and if so, where can I find the correct driver for my "System Speakers"?

Well try this

by OH Smeg Moderator In reply to Tried but didn't work

Open the Control Panel switch to Classic View and left click on Sound & Audio Devices.

Under the Sounds Tab make sure that Windows Default is selected and then click on the Audio Tab and make sure that the Sigmatel Device is listed there. If it is not listed left click on the arrow to the right and select it from the Drop Down list. Apply the changes and see if you have working sound now.

Thanks for the suggestion

by bamac86 In reply to Well try this

Thanks so much for the advice. I had already done those things, but just now checked to be sure they were still set that way. Any other thoughts? This is the craziest thing. I installed a new version of Quick Time last night and the sound actually works with it as well as the Windows Media Player... just not with system sounds or internet sounds. Grrrr. I have tried everything I can think of.

Thanks again for the suggestion!

Did a reinstall of drivers for SigmaTel. Nope. Nothing.

by bamac86 In reply to Download the drivers from ...

I reinstalled the SigmaTel drivers, but it didn't help at all. However, it seems logical to me that since the sound actually works with WMP and QuickTime that it isn't a problem with the audio drivers. I am so unfamiliar with all this, but are there different codecs (bear in mind that I don't even know what a codec does) for different applications? If so, maybe I am missing something there? Am at my wits' (and limited PC knowledge) end.

[edited to add] Also, when I go into Sounds/Audio and go to the Sound Theme and select Windows Default, then click on an individual sound to test it, the "test" arrow is grayed out. I cannot click on it.

:) Thanks all!

A couple of checks

Click Start, Run and type secpol.msc and press Enter.

Check to see if Windows Audio is set to start Automatically, if it is not, fix it.

You could try creating another User Account

and see if that makes a Difference. It is possible that you have a Corrupt User Profile maybe.

Tried all of the above

(OH Smeg) created new user account... still no audio from system.

(Jacky) tried the secpol.msc but didn't see any settings there related to Windows Audio... and the link to the Microsoft Support site only suggested things I have already tried.

This is baffling... there must be a solution somewhere.

My audio WORKS with Media Player and QuickTime. Now why wouldn't it work with system and internet sounds? I also cannot control volume, mute, play or pause from onboard control keys. I can only control those from within the Media Player and QuickTime applications.

Anyone else have an idea?

services.msc should have been the command to run.
