Onboard audio issue

[Invoker4984]

Hello everyone

So i've been having some audio issues the thing is the computer thinks that no headphones or speakers are plugged in even though they are plugged in the correct ports that used to work before and when i view device manager everything looks normal and no yellow triangle or any issues there and i have the latest drivers.

i also tried to uninstall and reinstall the drivers but no luck then i reinstalled windows still no luck

i'm on a windows 7 64 bit
Motherboard is : MSI 790GX-G65 Winki Edition

note: this a windows 7 but using the classic mode for more performance

Playback devices: http://img145.imageshack.us/img145/1981/playbackdevices.png

so did the onboard card die? or there is something else
also 'HD Audio controller' is enabled from the system bios

if there is any more info needed i will happily provide
thank you so much for any help

Most onboard sound devices can be turned off in the system settings. The Realtek drivers are a little bit buggy and will linger around inappropriately if they are left installed while the onboard device is disabled. Make sure that it is enabled. It could also share bandwidth with other devices, so make sure that everything is setup properly

If it is enabled and is still not detecting your headphones you should verify that the headphones themselves aren't dead. If the headphones work on another device, but not in your PC, then the onboard audio codec is dead

My headphones and speakers work properly on other devices so does that mean that the on board sound is dead, is there any tests or something that can be done to make sure?


Thanks

Try using an Ubuntu Linux LiveCD. That has a self contained audio stack which should work with most Realtek onboard audio devices. If it doesn't work in that, it will need to be replaced

EDIT: Just as a side note, since onboard audio devices often do not have their own oscillator they use a system clock for reference. If you overclock any of the system busses (such as the base clock in Intel systems) you can render the Integrated audio non-functional.
