Google it. Go to the manufacturers website and download the sound driver for that specific model of motherboard.
Delete the one you installed and any unknown devices.
Reboot the PC, Windows should detect new hardware and start to do the driver install wizard. Point it to the one you downloaded (or run setup if it came with a setup file).

If WIndows doesn't detect new hardware check if it is enabled in the BIOS first. 		pctek (84)
508976 2006-12-24 18:32:00 with regards to your last questions:
1 -Yes the link and everything you sent me is right, that is my computer.
2 - With regards to the " unknown" not that is not there any more, nothing related to sound is listed there. ( computer manager/services and applications)
3 - Control panel/ audio tab - I cannot change anything there. Volume tab indicates there is not device, and hardware tab shows a list, what is that for? I selected realtek AC97... however closed the window went back in but nothing changed.
4 - "Have u got some kind of USB audio soundcard as well?? Besides the onboard soundcard?", I have not added any hardware to this computer ever since I bough it new. 		parapa05 (11651)

508978 2006-12-25 22:26:00 Hello again,
I have done what speedy asked for last time, and now my comp. manager is showing one item with an exclamation mark, ( unknown), when I go to PROPERTIES/DRIVER DTAILS: C:\WINDOWS\SYSTEM32\DRIVERS\LVUSBSTA.SYS.
when I try t update driver:
MICROSOFT KERNEL AUDIO SPLITER
CANNOT INSTALL THIS HARDWARE...NO SIGNATURE WAS PRESENT
What can I do???:horrified 		parapa05 (11651)
508979 2006-12-25 22:41:00 Hmm, it looks like that LVUSBSTA.SYS belongs to a Logitech Quickcam.

Which has NOTHING to do with a sound card.

Have u got a Logitech Quickcam?

Delete ALL sound card entries in device manager.

Uninstall any sound card entries in add/remove programs. Then reboot.

Then reinstall the drivers off the HP site I posted before.

Then reboot again.See what appears after u boot back into Windows.

And if u downloaded the zip file from the HP site I posted before, did u unzip it? And did u run the exe file, if there's an exe file in it??

DON'T use the inf file in that zip file, if there's an exe file in it. 		Speedy Gonzales (78)
508980 2006-12-26 18:33:00 Good day,
Well thank you again, I have done what Gonzales has suggested and after a lot of reading, not understanding a lot, I found this: Description: lvusbsta.sys is located in the folder C:\Windows\System32\drivers. Known file sizes on Windows XP are 22016 bytes (50% of all occurrence), 19968 bytes, 39424 bytes.
The driver can be started or stopped from Services in the Control Panel or by other programs. The program has no visible window. File lvusbsta.sys is a trustworthy file from Microsoft. There is no detailed description of this service. File lvusbsta.sys is not a Windows core file. lvusbsta.sys seems to be a compressed file. Therefore the technical security rating is 14% dangerous.
- - Yes I have a camera but never had a problem with it int he past.
- - Also have noticed that there is not icon in my task bar.
- - I did go to the HP website and downloading and installed file. 		parapa05 (11651)
508981 2007-01-07 18:48:00 I believe I know the problem. Because I have an a720n and there was ONE hardware device that couldn't be detected, not by any of the drivers on the HP site, NOR HP themselves. I had to come across this just randomly, and I think this is what you are looking for:

www.realtek.com.tw

These are the High Definition Audio Drivers for Realtek, and why no one at HP knows about it, is a mystery to me. MAKE SURE YOU HAVE ALL YOUR WINDOWS UPDATES INSTALLED BEFORE INSTALLING (or else your computer will freeze). Try it out and let me know how it works. asdpoipoi-1@yahoo.com (my temporary email address) -Brad 		Bradd774 (11653)
