Exactly as it says. I have an HP xw8600, which I have been making a few changes to since having it. Here's the basic rundown: it originally had an NVIDIA Quadro FX3700. An older graphics card, so the way I got audio was through the motherboard's back ports. However, I then bought an NVIDIA GTX 1050 since I intend to use this for gaming. After installing it, I noticed sound didn't work. I checked the settings, and the RealTek High Definition Audio Output was gone, all there was left was three NVIDIA audio outputs (HDMI, DP, and DVI). I plugged my speakers into my monitor, and it worked, so I called it a day. However, only after a bit of time did I realize that it actually matters. The Front Panel's and Back Panel's Audio Ports are "missing", this includes the Microphone Ports. What I mean by this is in Advanced Sound Settings, there is nothing there, in Output Devices, there is nothing there. In device manager, there is nothing there. I have reinstalled RealTek HD Audio multiple times, I upgraded from Windows 7 to Windows 10, troubleshooters find nothing, driver updates find nothing, and the constant searching I have done to find a similar scenario has found nothing. I have tried for hours to figure this out, and I give up. If anyone has any suggestions or insights, I will be happy to use them.
