A search revealed lots of similar threads, but no good answers. So I'll try my own version:
Built myself a new rig with an MSI Z87-G41 motherboard, and used the onboard video and audio while I waited for my new GeForce GTX 750 Ti to come in. Audio out of the front and rear worked great, and then the card came today and I installed it.
However, after installing the card, the onboard audio no longer works. Can only get light static and a very high-pitched sound out of either, whether or not system mute is on or off. Removing the new graphics card and trying again doesn't help, so that seems to rule out interference from the card itself. Reinstalling the Realtek HD Audio drivers didn't seem to help, nor did upgrading to the latest version for my MSI Z87-G41 motherboard, from 6.0.1.7069 to the latest version 6.0.1.7111.
The most distressing thing is that it doesn't realize what's plugged into what back there. Both the Realtek HD Audio manager and the board explorer in the BIOS show that something is connected to the blue and pink plugs, when in fact it's connected to the blue and green plugs.
Trying to uninstall the NVIDIA audio drivers didn't help.
Trying to set the default device for output in the Sound dialog from Control Panel doesn't help; the device is either greyed out because it doesn't believe it's plugged in when it actually is, or it isn't associated with the correct plug in the back.
I have no idea how it all could have gone so south after working just fine before installing the new graphics card.
I'll provide any other details needed. Thank you!
