Hello!

The first step here is to go ahead and check the service Windows Audio.

Do you know how to do this?

Windows Audio should be set to
Startup type: Automatic
Make sure it is Started!

Have you installed any audio enabled applications? They could be incompatible with Windows 7 and could cause this.

Is this build 7000 of the Windows 7 beta? Some of the later builds are not exactly very stable.

Note: later builds are also illegal for download, and considered pirated, if not authorized by Microsoft first.

I just checked the database to find this potential solution: Driver Page for AC'97 Drivers

The page says it has the latest driver, one that was update 2-17-2009.

I would say to get a new sound card, one that will work with Windows 7. I have read other forums about this problem, and re-install did not fix the problem.

Purchasing a new sound card to run beta software is a little extreme at this point. If the sound card worked before there is some level of compatibility with Windows 7. Have you tried the R1.14 drivers or picking the drivers manually from the list in "add hardware"? Some people are having the exact same issues you are having and suggest using them. Can you confirm, if you were to boot into another OS, that the sound card is able to work? When the OS is officially released, compatibility may go up. Remember, this is a beta so issues are to be expected.

It's not just the drivers that may be at issue. Rather it can be incompatible software that is addressing the sound card in an unacceptable way. Do you have any other audio aware applications installed?

Even uninstalling the other apps may not fix things (even if they are at fault) - and it may require removing the audio drivers and installing fresh one's just to see.

With all due respect DJBPace07, I did not say to get it now. I would recommend getting a new sound card for the actual release. Sorry for not clarifying, as I mean't to say that if you are planning to get Windows 7 at release time, I would recommend buying a new sound card -- or waiting it out to see if compatibility gets better.

I am thinking you may be missing a CODEC, which may be reliant on a certain service that may not be running. That was the issue I had back in Windows Vista toward the beginning of the final release, was a service causing a conflict with Audio. To find out, the hidden service Windows Audio Endpoint Builder (PID 1248) was not enabled. I also had a similar audio conflict in AudioDG.exe, which was easily solved thereafter.

I once again agree with Usasma, as the fact that certain software may be sending the wrong signals and possibly locking the drivers or making them incompatible. As Realtek stated on their website help, the drivers were tested and should work with Vista 64 Bit and Windows 7.

Ahh...I thought you meant to get it now. After a quick websearch, the audio issues with AC'97 are not uncommon with Windows 7. For some users, the newer drivers don't work or there is an issue with driver initialization. Oddly though, after reading through some of the searches, users have reported that the audio driver is correct, but it is misidentifying the audio hardware. A few users have tried Vista drivers from several months ago with success. Compatibility should be better at launch. Codec issues should have manifested themselves earlier when you ran audio playback software. You could try running your audio files in an alternate media player like VLC to check.
