Realtek Audio not detecting analog inputs

I know this is an old thread, but I recently started to experience the exact same problem as the person in the first post:

I have a Gigabyte GA-P55-UD3R that has had no problem for quite a long time using Windows 7 64 bit. Recently after a reboot, the integrated Realtek audio no longer detects any analog connection (tried with mic/speakers/headphones) in any of the jacks.

I removed the current drivers using add / remove, rebooted, then installed the latest drivers from Gigabyte, then I tried Realtek directly, and finally the default Windows audio drivers. I also tried removing the drivers with driver sweeper, directly from device manager, etc. and installing a fresh set of drivers. Additionally, I disconnected the front audio jacks from the motherboard in case that was causing a problem. Windows detects the sound card and there appears to be no problems in device manager.

I've gone through every available option in the Realtek sound control options, but I'm at a loss. I have a USB headset that works without a problem, but I can't get these darn analog speakers to work. Any advice? Before anyone says it, 'set default device' is grayed out as an option for the speakers.

I ended up purchasing an audio card, bacause I thought that the issues were in the integrated audio card in my motherboard. This didn't solve the issue.

After that I found out what BrockH suggested for solution and tried to disable front panel jack detection. This gave me tiny improvement and now for the first time in about two weeks my speakers say something. Only now I'm getting audio only on the right hand speaker. This is very frustrating.

I followed an older post from 2012 From Bunno and it worked!! I went to the control panel (his words below)
In the realtek audio manager (mine shows up in the system tray as a little orange speaker icon) there is an unlabeled icon that looks like a folder. It doesn't even look like something you should be able to click on, and what the heck does a folder have anything to do with sound, your audio devices, or front panel jack detection? Nothing, that's what. You'd never know that if you click on it, there is a single checkbox option within to "Disable Front Panel Jack Detection", but there is. Go in there, check the box, and Realtek will no longer rely on this broken detector to populate your Microphone and Speaker panel tabs, and you'll be able to get sound again. I know some of this was hinted at in other posts, but there it is.
As soon as I clicked on that folder and changed the setting walla I had sound!
