Hi,

I have a new Dell dimension E521 with Windows vista premium pre-installed. Yesterday my speakers suddenly stopped working. I have already tried uninstalling the sigmatel drivers, but this didn't help. On the internet I have found evidence that there is a problem with sigmatel audio drivers and windows Vista.
However, the sound worked fine for the first few days, so I doubt this is the cause of the problem.
Under device manager there doesn't appear to be a problem, but the sound icon in the bottom right corner shows a red cross. When looking at the properties it says: " no audio device installed"

On other websites people with an intel motherboard have found compatible drivers off the intel website. I think my motherboard is AMD based, so can anyone please help me?

P.S The problem appears to be widespread. Look for "sigmatel "no audio device installed" in google.

Hi, I installed this model PC for a colleague several days ago, but didnt have any issues.
Try un-installing the audio device, reboot, and windows should re-install.
