No Audio Output Devices is Installed- Sony Vaio

[khoi94]

I have a bluetooth headset that already paired but it is unable to use because there is no audio services to work with. When I run the troubleshooting for my sound, it couldn't identify the problem. In my device manager, the bluetooth audio is gone (it used to be there) and i also have many unknow device that related to bluetooth. I used to played with registry when i was trying to fix something else, maybe that the cause, but when i run the Sfc /scannow, notthing seems wrong. I have been searching solution for this problem for a month and yet, notthing works. Please help, im using sony vaio Model # SVS15116FXB. I also tried to download some drivers from the sony sites, but they are useless.

I would uninstall all the unknown and Bluetooth devices listed in the Device Manager. Leave that off until you get the basic sound going again. Restart the PC after uninstalling all the Bluetooth and unknown devices.

If the PC's sound device is enabled in the BIOS, Windows should detect it and install either the regular drivers or at least the generic, basic function, HIgh Definition Audio Drivers (Codec). If its not being detected and installed, the first thing is to check the BIOS. If its disabled in the BIOS then Windows will not see/detect it. If its enabled in the BIOS, reinstall the Intel motherboard chipset drivers. One of the things the chipset drivers do is define (identify) all the devices on the motherboard. This too affects whether the sound can be detected.

Hi,thanks for reply, these are unknown devices hardware ids, I tried to uninstall and reinstall it but the problem remain the same. And I cant update the driver for some reason, idk why.

If the Sony downloads for your PC do not list one, Go to www.intel.com Use the Intel detection program to scan your PC. It will (should) list the available chipset driver.

Did the Driver not Install ? ....

 

[fireberd]

Although a "last resort" and I don't like to suggest it, a reinstall may be in store given the problems and what "won't install".

 

[khoi94]

No,the driver you gave me was installed successfully, but the problem still there. Plus, these are some of the unknown devices i tried to update in Device Manager.

Where did you try and Update the Drivers from ? ....

 

[khoi94]

I chose the option "Search automatically for updated driver software"
