Hi,
I'm afraid there is no AMD HD driver among the list of drivers . I only found AMD HD graphic driver.
Additionally the only audio driver available to install is the IDT HD audio driver.
I tried to run the diagnostic tool . On the home screen under Updates & Tuneups there is a warning sign and "imortant message available"
When I click on HP message
the important message is "create a recovery set"
I don't have USB sitck or DVDs to use right now.
Can I bypass it and get the issue with the audio resolved?
