Invalid audio driver

[qorda1]

Hi

This PC dc5800 worked perfect on windows XP with its HD5570 ATI graphics card.

Yesterday I did a clean install of Win 7 Home basic and all seems well except that there is no sound.

Speakers are well connected and light is on.

Bottom bar shows speaker with a cross "no audio output device enabled"!

Right clicking the icon shows no playback device icon!

Device manager sound controller shows both High Definition Audio Device and USB audio device. Both are working "normally" in their properties. disabling re-enabling and restarting computer changes nothing.

The audio driver downloaded from HP site "ADI high definition SoundMax" sp45615 refuses to install stating that this "not meant for this operating system", even though HP recommended this after autodetecting my Win 7 32 system.

Windows trouble shooter states "no problem found".

Wasted all day today on this conundrum.

Advise pls.

Hi:

If your AMD Radeon HD5570 graphics card has a HDMI port, it automatically disables the onboard audio in the BIOS.

You need to go into the BIOS>Advanced>Device Options>find the onboard audio setting.

It will be set to Disabled.  Change the setting to Enabled.  Save the setting there (F5), and again when you exit the BIOS.

Upon restart and going back into Windows, the onboard Soundmax audio should be working again.

The  High Definition Audio Device that you see listed in the device manager needs the ATI HDMI audio driver which you can get from the Realtek site at the link below.
