1. Just clean installed Windows XP Pro SP2 and did not hear any sounds.
2. Then installed Nvidia Nforce2, ALL IN ONE driver ver.1.16 downloaded from Asus (included LAN, audio etc.) - no sound!
3. Tried to install another audio driver: Realtek AC'97 Driver & Application ver.3.45 WHQL, recommended for A7N8X-VM/400 by Asus - no sound!
4. Tried NVIDIA nForce Unified Driver 5.10 - no sound!

Could you help me to fix this problem, please?

if you actually check the ASUS overview for this board you'll it says it has a C-Media 8738 audio chip
see http://uk.asus.com/product.aspx?P_ID=OYMrFEShYfp6m1dg
neither the Realtek or nForce drivers will work with that

Despite that they offer Realtek drivers for download...and the spec says its Realtek ALC650
either they've made a mistake or two versions of the board exist with different audio codec chips

I've tried blowing up the photo of the board, and I can't make out what it says in the audio chip. Try reading it yourself off your own board. It'll be a small black chip somewhere near the back panel.
In the meantime try downloading from this C-Media site
http://www.cmedia.com.tw/en/DownloadCenter_Detail.aspx?pserno=0&dtype=ALL Its the CMI-8738 that you need


If that fails, try try the latest Realtek AC97 from http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=23&PFid=23&Level=4&Conn=3&DownTypeID=3&GetDown=false#AC

Thanks for your post, JonS.
As a matter of fact, what exactly is written in the manual:

"#12. Audio CODEC. The Realtek ALC650 6-channel Audio CODEC is AC'97-compliant onboard audio solution for PC multimedia systems."

I've checked it up twice, and yes, I saw ALC650 at the chip on the board.

then try the AC97 download from the Realtek page I linked to

inspires a lot of faith in the company though when the website has such incorrect information...

OK! On more try's completed. Just installed newest available Realtek drivers for AC' 97 ver. A4.06, release 2009-10-01.
It's a pity, but nothing happened - my "renovated" PC stay silent.

Did I miss smth. in BIOS preferences... or it could be a hardware problem.
I'd be very thankful for any advice/idea!

only thing in BIOS would be an able/disable entry somewhere for AC97 sound

Have a look in device manager - does it show any missing entries in there?
And what does it show under "Sound Vide & Games Controllers"?
Its just possible Windows update has done its common trick of misdetecting an AC97 controller and installing the wrong driver

I presume the speakers ARE plugged in? If so, into which port? Should be the lime green one. And have you used front or back ports on the PC?

I found one place in BIOS: Audio codecs - AUTO. Nothing more.

There're no yellow "?" buttons in the device manager. The AC'97 driver is shown at the right place after all security updates installed.

The speakers are tested with another computer and video player; properly connected through the lime green input.

Something mystic I never met before.
It looks like the audio pink/lime I/O simply does not work at all, and I have to think about purchasing a PCI sound card.

P.S. Sorry for the late reply. Got some kind of flu and spent a couple of days between pills and warm milk.

which AC97 codec software does it actually show as being installed?

Also - have you just rebuilt this machine or refitted the motherboard?
If the m/b has connectors for a front audio panel, and these are either not plugged in, or not jumpered "closed" then the rear audio plus wont work

The current driver installed -
Windows 98Gold/98se/Me/2000/XP/2003(32/64 bits) for Driver only. (ZIP file) A4.06 2008/10/1
from:
http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=23&PFid=23&Level=4&Conn=3&DownTypeID=3&GetDown=false

The previous motherboard just died and I replaced it by A7N8X-VM/400 at the same case. I tested the rear port pink/lime holes connection to the speakers first. No sound.

The front sound panel in this very case could be connected only by physically connection the rear pink/lime holes to it. So, if the rear I/O does not work, the front panel would never work at all, and it doesn't

you're missing both points of my question

1) In device manager, what does it actually call the AC97 codec. I'm not interested in what you've installed, I want to know what Windows SAYS is installed. The two may be different as Windows update often misdetects AC97

2) this motherboard has a connector header for front panel audio. If you've not attached any leads to this you'l need to jumper this header to close the circuits and enable the rear panel. If you look at the diagram on page 1-17 of the online manual you'll see there are two (blue) jumpers that need to be in place. Asus often did not pre-fit these. Check your board visually and see
No jumpers = No Sound

Dear JonS!

YES! It was "No jumpers = No Sound" issue. I installed the jumpers the way you recommended, and it fixed the problem.

Thank you VERY MUCH for your help!

Good!
got there in the end
I just wish they'd put the info into the manual. As far as I can see it doesn't mention the need to jumper it anywhere
