My sound stopped working

A couple of days ago when I went to adjust the volume setting on my Vaio SZ, I noticed I was getting no response. Pressing Fn F3 or F4 was doing nothing other than making the volume setting show up on the LCD. When I selected the little speaker in the task menue it popped up a dialog box that reads "There are no active mixer devices intalled. To install a mixer....."

Any ideas. I'd love some sound again.

 

Try to reinstall the sound drivers. Windows thinks that the driver has been uninstalled, butit probably hasn't been.

 

I reinstalled sonic stage. Things appear to be working now. What was funny is that when I checked the drivers individually, they all checked fine. Strange.

 

Sometimes drivers need to be reinstalled. It was probably just a Windows problem, and that it couldn't find the driver for some reason, or that it was damaged. If a file that belongs to the sound card drivers are deleted, then the whole driver may not function properly.

 

Ok, this is reoccuring regularly now. My sound stops all the time. I re install sonic stage and I get sound back until I start opening and closing audio sources and then the sound just disappears. When I click the audio speaker icon, I get a message that there are no active mixers installed. Very frustrating to have to reinstall sonic stage every time I want to hear anything. Any thoughts.

 

Ok, I have updated the SigmaTel High Definition Audio Codec to their latest which comes with a warning it has not passed Microsoft compatability yet. We'll see what happens.

 

No joy. The sound still stops working eventually when you try and open up a new source. A DVD or an MPEG or something. You install the driver, it works fine and then eventually when you open up a new source, the sound stops working with a no active mixer devices available warning. Still open for thoughts.
