Audio Panel HP DC 7700 Minitower case with Hp 7600 motherboard

check the memory or graphics card . then motherboard
another thing HP doesn't support W8 for the dc7700 eventhough windows 8 works for this model .

You have a problem with HP connectivity. When I moved my dx7100 motherbard into another casing I experienced that error and also chassis fan not detected error. Chassis fan error is easy to remove, You only need a fan with at least 3 cables (with sensor) and plug it into 4 pin chassis fan connector. Audio conector have 10 pins (eight pin missing for orientation (with followed numerication
2 4 6 10
1 3 5 7 9
If you only want to get rid of the error ( with no use of back audio(use of another soundcard)) then short pins 2 and 7. But if you want to use back connectors, then you must bridge with jumpers 1-3 for microfone, 5-6 for audio L and 9-10 for audio R.
I've bee searched thru internet and didn't find this trick anywere.

HI,
Installing the HP DC 7700 Drivers is a little tricky. You may have installed the drivers and its not working I guess. This is because the HP DC-7700 has HD Sound and it required "Microsoft Universal Audio Architecture Bus, which can be downloaded/ installed from the following link. Choose the Operating system you have on your PC and get the drivers.

You will now get an option 'Select Operating System'. Click on the OS that you have installed in dc7700
Now download the following drivers Driver - Audio Driver - Chipset Driver - Graphics Driver - Modem Driver - Network
and install the same on your dc 7700. Now you will be able to play sound and also browse internet after you configure the LAN (TCP/IP) properties.

Audio drivers for this computer are here:
