HP Folio 9470 Windows 7 says No Audio Device plugged in, No Sound
Here is a good one. I have an HP Elitebook Folio 9470m Ultrabook downgraded to windows 7 Pro. from 8 pro. Sound worked great when first set up. Sales person went overseas with it and sound stopped working. Headphone jack looks and feels ok, not loose, snaps in at right places. Icon on desktop shows speaker with red x. Hover shows No speakers or audio device plugged in.
Uninstalled audio drivers from device manager and rebooted. (did not remove drivers at this run). no change.
Downloading windows 7 drivers from HP for this device using serial number listed under battery results in setup program for audio saying "The hardware detected is not supported by this IDT Software package"
Downloading Windows Vista and Windows 8 drivers from HP.com has same results.
Uninstalling drivers for audio AND deleting drivers then rebooting. Same results.
Restore point to earliest saved point has same results.
SFC Scannow shows no issues.
I will be setting up a usb with Linux mint to test hardware this afternoon.
