We have a Windows 7 laptop giving us some issues. It's relatively new and on a factory image of Windows 7 Home Premium. A few days ago, the user stopped getting sound from the internal speakers. Everything looks fine in the sound properties, nothing is muted, settings were restored to defaults, etc. We also tried removing the sound card and letting Windows find it again. That works fine, but no sound still. We know the internal speakers work as we can get sound in tests outside of Windows. We also get sound just fine if we plug in headphones.
Any ideas where to look next?
