Windows 7 NO SOUND!

[redsvienas]

Hello, thanks for your time in advance.

I have been using win7 pro 64 with my new system for nearly 6 months. I had no problems until now, but since the beginning of new year i have this no sound issue.
Appriciate your help.

i have gigabyte x58a-ud3r mobo and i used to have the sound coming from my monitor with hdmi output of my gpu (nvidia gefore gtx 460), i sometimes also use the audio jacks in front or the back of the case to get audio to headphones.

now i tried several options but what i get is this.

in device manager, i see no problems and sound cards look fine, i already updated it to latest realtek drivers after having the problem but no luck. when i go to dxdiag in sound section i see no cards listed and below its something written like "windows audio service disabled, go to services to enable it". but when i go to services.msc i have nothing related with sound in the list like "windows audio" or whatever. i tried deleting all the sound drivers and reinstalling, disabling the nvidia ones and just leaving the realtek or reverse. but nothing helped. when i go to control panel and click on "sound" nothing shows up either. when i click on realtek hd audio manager i just get a blank screen. it says "you are seeing a blank page because there is no sound device working on your system. to activate GUI, please plug a sound device"

I checked to see if there is anything in bios to be enabled. the only thing i see in bios about audio is "azalia audio" and its set to automatic. the only other way to change it is to disable it.

any suggestions please?

Welcome to Seven Forums redsvienas. If there is no Windos Audio listed in services.msc, then you have a problem. You might try the System File Checker first:

But will likely need to do a repair install:

Thanks for your advice,

SFC/Scannow came back with no problems. Do you think I still need to do the repair install? Or buying a new cheap usb sound card would help me solve it? I am not sure if its a hardware or software issue.

The actual service is missing, now at least, it's a Windows problem. Did you do any "tweaking" that might explain the missing service? The repair install will repair windows, and you won't lose your programs and documents, and settings. It will likely be the best bet, as a missing service is not normal. A Guy

Have you modified your registry any?

Backup and/or System Restore?

I take it that you have no backups or System Restore points that you can use?
