Notebook Audio

Hi there,

A few days ago I updated from the Windows 8.1 evaluation to the full 8.1 release and since then my audio has not been working. In the control panel, "Digital Display Audio (AMD High Definition Audio Device)" is listed as unplugged. The audio icon on the taskbar is Xed out and clicking it runs the error finder in vain. Speakers no longer show up in the device listing although now that nothing is working I'm not sure if they ever did or if audio just came through Digital Display Audio. Headphones do not show up as playback devices and the volume controls on the keyboard and taskbar are inaccessible. I have never used external speakers.

The Windows 8.1 update seemed to wipe all of my HP and AMD software that came with the laptop so I reinstalled the HP Support Center and searched for driver updates and all that jive but everything shows as up to date. I don't know what else to look for as most of the forums I've seen seem to be talking about their HDMI out sound not working when plugged into a TV and I'm just trying to have sound, period.

Thanks in advance to anyone who can help. It's been a few days and it's fairly annoying when everything was just dandy before updating.
