Can't install sound driver.

I'm using Presario c733tu, and trying to install my sound driver thru Windows Update

then

then


Why?

Try this link instead of Windows Update:

The driver don't work, I can't hear sounds.
And the driver is not digitally signed.
Is there a problem with that?

My Computer >> Properties >> Hardware >> Driver Signing.

Change the option to Ignore.

Try to install it again.

If it doesn't work, download the Microsoft Universal Audio Architecture Driver that need to be installed before installing the Audio Driver:
ftp://ftp.hp.com/pub/softpaq/sp33501-34000/sp33867.exe


Then download and install this driver instead:

ftp://ftp.hp.com/pub/softpaq/sp36001-36500/sp36408.exe

Installing this driver may result in an error. But continue with the following steps to get the audio driver installed correctly.
Please follow the below steps to install the driver correctly:
Start >> Run >> type devmgmt.msc >> Enter.

Right click on Audio device on High Definition Audio Bus and click Update driver >> Select "Install from a list or specific location" >> Next >> select Don't search, I will choose the driver to install

Click Next and then select Sound, video and game controller from the list >> Next >> Have Disk >>Browse for the C:\swsetup\sp36408 folder and the double click the V32 folder. Select the .inf file, click open and Continue with the onscreen instructions.

Also, what operating system are you using? What do you think caused this problem?

I already did that. Nothing works, am using XP. I don't know what might cause the problem.

Heh... Strange! Did your Operating system come with XP or did you switch it from Vista?

Try this installation:

ftp://ftp.hp.com/pub/softpaq/sp33501-34000/sp33571.exe

I dual booted it with Vista.

Even in their website, there's no useful drivers for XP.

Ahh! No wonder.

Unfortuantely HP doesn't provide that driver. Nothing we can do I guess.
