Front and Back 3.5 mm audio jack not working

Solution
I suspect the problem is linked to your video card. Odd, right?

A video card you add into a PCIe slot has no real way to get an audio signal from a mobo audio system. But so many people want to use the speakers in their monitors for sound, and it's really handy to have them fed via the HDMI cable coming to the monitor. The HDMI design allows this. So most video card makers now include an audio system on the video card specifically so that system can feed audio through the HDMI cable from that card to the monitor.

The "catch" here is that, while a computer may have more than one audio system in it (like yours, with systems on the mobo and on the video card), Windows can only use ONE of those systems at a time. Now, VERY often when you...

go to bios see if audio is enable.

find audio driver, in windows 10 look under device manager, uninstall the driver and restart, after reboot windows will look the driver, or requires you to install audio driver from your motherboard cd driver

The "catch" here is that, while a computer may have more than one audio system in it (like yours, with systems on the mobo and on the video card), Windows can only use ONE of those systems at a time. Now, VERY often when you run the driver installation utilities that come with your video card, it also installs that card's audio system drivers AND changes the Windows setting so that Windows will use that system. Then the jacks on the back panel of your mobo no longer have any output signals!

You can keep using the system this way, and let sound come from your monitor's speakers if it has any. Or, you can tell Windows to use the mobo audio system instead and have sound available from your back panel and front panel jacks. Of course, that means you need your external speakers working, not the ones inside your monitor. To make the change, go into System and find the Sounds control panel. In there you'll find a tab that allows you to make separate selections for the Default Playback Device, the Default Recording Device, and the Default MIDI Device. The Default Playback Device is what you want to adjust. I expect it shows a Realtek system (on your mobo) and a second system on your video card. Choose the Realtek mobo system, confirm and back out. Now try your front and rear jacks for sound.

In that panel there ought to be two or three items where you can set your Default Sound Playback Device, Default Recording Device, etc. For each of them there should be a little rectangle with a drop-down arrow. If you click on it, it will show you a list of your possible choices, and you pick one. Both the Playback and Recording items should be able to show you the mobo-based audio system as well as the one on the video card.

If that device (I assumed Realtek) is not there, go to another place - Device Manager. Look there under the Sound devices. If there is a Realtek device but with a yellow triangle warning beside it, it probably needs its device driver updated, so you can right-click on it and do that. If it is there but has no yellow flag, you can try to force it to renew, as follows:

1. Delete that device altogether. Back out of Device Manager and out of Windows and reboot.
2. The machine ought to find that it has a Realtek audio device that i does no "know" about and then install the required device driver for it.
3. Check in Device Manager that it is present with no yellow flag. Then go back into the Sound panel and see whether it is there as a choice for the selection of Default devices for those functions.
