I have a Sigma Tel High Definition sound card. Lately, every other day or so, my Sound Playback Default Device in the Audio Tab of "Sounds and Audio Devices" reverts from my "Sigma Tel" to the "Modem #1 Line Playback" default. this does not allow me to play much web sound content. I have checked the box to Use only default devices when I have activated my Sigma Tel card. However, it continues to change.

Furthermore, when I do a regular System Restore to try and recover my Sigma Tel sound card it fails. I can only recover when I boot up in Safe Mode and choose "Restore from Last Good Configuration". However, my Sigma Tel sound card setting doesn't stay for long after that.

Any idea how to stop my sound card from changing? I am using Windows XP, SP3.

I had a similar issue once with a keyboard. The driver version was not for the OS it was running under.

Look for an updated driver.

I have had the computer for 2 1/2 years and it has only been recently that I have had this problem with the sound driver.

Windows update MAY have installed a newer driver then. Just a guess. Look in Control Panel> add/remove. Look for any updates that were installed about the time you started having problems.

Copy and Paste the update to Google and run Google to find out what the update was for.

There are numerous Windows XP and IE 7 Security updates listed in the Add/Remove section of the Control Panel. However, there are no specific updates that appear relating to my sound driver that I can tell.

There is a newer sound driver available for my card. However, it is listed as an optional installation and not a required one. Should I update my driver? If so, do I uninstall the current sound driver before doing so? Your thoughts...

It shouldn't present any problem by updating the driver. You shouldn't need to remove the present driver first.

You might want to check on the settings for what device to use for sound. It may have somehow changed.

Do you have a modem in the computer?

Go to control panel> Sounds and Audio> audio. Verify the device listed in the default sound playback box is your HD sound device.
