No sound after reinstalling windows

[Lerton11]

After I reinstalled windows, the sound was gone and I mean the sound chip integrated in the computer. I tried installing all kind of drivers, but nothing helps. It shows as there is no sound device conected. So is there some software/driver that woukld make computer see and use the integratedsound chip?

Hi:

What is the full model number or product number of your PC?

The product number can be found on the same sticker as the serial number.

HP compaq DC5700|

P.s. Doing troubleshoot doesn't help

Hi:

You should be able to use the W7 32 bit audio driver directly from Realtek.

Accept the agreement.  Download and install the 1st driver on the list -- 32 bit.

If that doesn't work, use the Vista Business 32 bit audio driver from the dc5700 support page.

Neither of them worked. It still shows me no sound icon and when I press the icon it shows that it detected a problem and when trying to fix it, it can't fix it, shows as if no sound devices are connected.

No ideas for fix?

Unfortunately, not from me.

I have worked on many dc5700's/dc7700's and those drivers should have worked.

I just got news, that the actual name of pc is HP Compaq DC7900. But I am guessing that changes nothing 😞

It changes everything since the dc7800 and dc7900 use a different audio chip than the dc5700/dc7700 does.

You need this W7 audio driver for the dc7900...

This package contains the driver for the ADI High-Definition (HD) Audio CODEC in the supported desktop models and operating systems.
