Device Manager shows sound device is working but still no sound

Jimnetta · Jan 22, 2010

My Windows XP on my Sony Vaio -vgn-t370p laptop does not have sound anymore. When I look in the device manager it shows that all devices are working properly but ( there are not yellow question marks), I still do not have sound. Please help?

Hi

What Service Pack is your XP at?

Did your sound just disapear or did you have a malware infection?

Have you checked that the volume is not muted?
Also check in Services (Control Panel > Administrative tools > Services) that the Windows Audio service is set to Started and Automatic.

What I would try is the below and if you are at SP2 only then install the UAA driver from HERE and reboot, possibly even re-install your audio driver once the UAA driver is installed.

Or if you are at SP3, then try the below originally posted from muskesnipe

Goto Start>Run and type in regedit , then click OK.
Click the plus signs in front of HKEY_LOCAL_MACHINE, SYSTEM, Current Control Set, Control, and finally, click Windows.
In the right panel you will see CSDVersion.
Right click it, choose Modify.
In the highlighted input window, you should see 300. Change it to 200.
Click OK, close regedit and restart your PC. Windows will now think it is SP2 and allow you to install the HD_Audio/kb888111xpsp2.exe and your Sound Driver.

Make sure to reboot and then test your sound BEFORE, changing the value back to 300.

Then follow the same steps to change it back to SP3. Change the 200 back to 300.
Click to expand...

Your Sony Drivers are HERE
