Model: Inspiron
Driver: SigmaTel High Definition Audio CODEC

Hi. I recently upgraded my Inspiron from Windows Vista Home Premium (bit) to Windows 7 Ultimate (bit). The upgrade was very successful with the exception of audio problems.

The problem is very strange, at least to me. I have three audio ports in the front (two headphones and one microphone). Both of the headphones work fine, but the microphonoe port doesn't work anymore. This problem came about after my Windows 7 Ultimate upgrade. It did not happen when I was still on Windows Vista Home Premium. I really don't know what the problem is. It seems that the audio cuts off when I try to go into the "Recording devices" selection when I right-click on the volume icon on my taskbar. The audio cuts off.

An example error message would be when I choose Recording devices while my Windows Media Player is running (playing music, too, of course), I would get this message: "An audio device was disconnected or reconfigured. Verify that the audio device is connected, and then try to play the item again."
Other audio problems would be video games such as Counter-Strike (for those who are familiar with this game). I would start the game, but there would be no sound. I minimize and there's still no sound. It's only when I exit the game that my audio would return.

Again, I'm not exactly sure what the problem is. Maybe my model (Inspiron ) does not support Windows 7 Ultimate? Are there driver updates for my SigmaTel High Definition Audio CODEC driver?

Any help or suggestions would be greatly appreciated. Thanks.
