I have just booted up my HP Pavilion dv6-6b09sa (running on Windows 7) laptop to find that the sound icon has a red cross next to it and it claims that 'No speakers or headphones are plugged in'. In the Control Panel it states that the AMD High Definition Audio Device is Not Plugged In. As far as I know, I've done nothing to cause this. I have already tried: System restore to yesterday at 10pm; Instalation of a TDI driver from the HP website, however I do not know how to edit/disable/delete the old driver. I'm completely clueless about these things. Please help, I'm at a complete loss. Hi, You're welcome Try the following.
