Hey all,

I am trying to fix the audio on my Mom's computer.  She said that one day it just stopped working.  I have tried many different solutions to get the audio back with no luck.  

The sound card she has is called "SigmaTel Audio High Definition".  I tried uninstalling it in Add/Remove Programs and then reinstalling it when Add new Hardware starts up after reboot.  When this happens, it won't install because it says that a device attached to the system is not working.  I tried rolling back the driver, and that helped remove the resource conflict in Device Manager.  However, the audio driver from Dell doesn't seem to do anything.

Any tips?

Thanks,

Christian
