Cannot find Realtek in my Device Manager

I'm just going to focus on your onboard audio..... After reviewing your data, I'll explain
a) What I see as the problem with your onboard HD audio device
b) How you can visualize the problem for yourself
c) What you can try next

As I see it, the onboard HD audio controller isn't detecting the onboard HD audio device. This can happen if a) the audio device failed or b) the controller, itself, isn't working correctly. Windows won't install Realtek because it doesn't see the device the Realtek driver is supposed to be for.

I believe you should be able to see this problem yourself, if you tell Device Manager to View Devices by Connection. DevMgr will then show you how your devices connect to each other instead of by category. I provide a Win 7 device manager snapshot of my own computer below. (Coincidentally, my computer uses the same addon ATI Radeon 5450 as you do)

Open Device Manager. Click View->Devices by Connection. To see how devices connect to the computer PCI bus, expand ACPI->Microsoft ACPI->PCI bus. You should now be able to distinguish between the two audio controllers.
=> The onboard controller connects directly to the PCI bus
=> The contoller on the ATI card connects through PCI Express chipset

Note that each audio controller should have at least one audio device connected to it. My guess is on your computer you won't see ANY audio devices connected to your onboard audio controller. (see my example from my computer below)

If the onboard controller can't detect the onboard audio device, Realtek will never install for that device.

Things to try:
1) Look through all BIOS setup menu pages again. (Be sure to look through all setup menu pages) Look for an option name such as onboard audio or integrated audio. Disable it and boot up. The onboard controller should disappear from DevMgr. Then reboot with onboard audio enabled. The onboard controller will reappear. See if an audio device is now detected.

2) After step 1) if still a problem, try uninstalling the onboard audio controller driver again. Tip: Instead of rebooting at this point you can also click Action->Scan for Hardware changes. Windows should reinstall the driver and the controller try and detect the audio device again.

also in dxdiag its showing "No sound card was found. If one is expected, you should install a sound driver provided by the hardware manufacturer".

1. First, an editorial note: You don't need to click Reply (which inserts a quote of all of the prior post) unless there's something specific in it you want to include. (Not inserting a quote "everything" makes the thread easier to read for others) For cases where you might be responding to several people, simpy use the @ sign followed by their user name does the trick. Example for case LookinAround
"@LookinAround" would appear as below (I added the " " so you can see it's affect. Normally don't use the double quotes to get things such as the two references below)

@LookinAround
blah blah blah

2. I downloaded the P5G41T-M LX User's Manual (English). See BIOS section 2.4.3 about Chipset settings

> Go to BIOS Advanced tab
> Click Chipset. Under Southbridge Configuation, appears there should be Audio Controller option you can enable/disable

See if that lets you toggle onboard audio enable/disable. Also it may not help, but won't hurt, to try install the chipset drivers again.

Sorry for the inconvenience.I found the option to Enable audio controller,it was already enabled.I disabled and booted,then enabled again( just hit and trial),it didnt worked too.

I agree with lookinaround that the next thing to do in this troubleshooting is to
1. (re)install chipset driver from: http://support.asus.com/download/download_item_mkt.aspx?slanguage=en-us&model=P5G41T-M LX#
or direct link: http://support.asus.com/Download.as...n7.zip#Intel_Chipset_V9111019_XPVistaWin7.zip

2. then reboot and try to re-install your hd audio driver.

@misor
I did that, but it didn't worked.I also checked Windows audio services,they are running too.
