[SOLVED] Speaker port disables microphone port ?

[Absolute.Red]

Motherboard: GA-B75M-D3H
Processor: i5 3570
RAM: 8GB
PSU: Corsair VS550

Having trouble with my audio devices.
What's happening is, when i plug in the 3.5mm speaker jack into the back port of the motherboard, the back mic port(Mic plugged in) disables itself and the Line-In(
Nothing plugged in) just gets enabled automatically.
When i remove the back Microphone from the port, the system shows the mic plugged in even though there is nothing connected and Line-In disappears. But if i remove the speaker jack, everything just goes normal.
Its not the speaker cable as i have tried with different cables.
and while speaker is connected it works fine but time to time the cpu usage goes to 100% and freezes for a second or 2 and task manager shows windows audio endpoint builder is using all the cpu.

any idea what might be the issue?

If reboot does not fix that then socket is broken.

do you think keeping the speaker jack connected to the port will cause any damage?
removing the microphone makes it so that i dont get any cpu usage spikes.
i can live without back microphone but need the back speaker.

I thing that switch inside Mic socket may be broken and prevent motherboard to know that microphone is unplugged.

For Line In check how audio input and output management is configured in your audio control panel software settings. Some of them have an optional setting which disable front ports if back ones are use and vice versa.

this issue just appeared out of nowhere. Everything is set to default. i have made no changes since the os was installed. I never even installed any different audio device drivers. everything is done by windows update.
edit: when i try to uninstall the audio drivers from the computer management panel, the drivers just reinstall themselves.

Physical ports may broke exactly without visible reason. Because built by lowest bidder and become old enough to broke due to coupling/decoupling stresses. However windows updates sometimes are not so harmless. By the way try to reinstall your audio panel software (Realtek, Nahimic, etc.) at first.

i did install a realtek driver from the motherboard support page but the issue persisted.

Then you have a task to replace broken Mic socket in hand. Or at least try to disconnect broken switch in socked with a needle. But disconnect your computer from wall before.

By the way are microphone in front socket works together with speaker in back socket? If so then you can use them in this configuration.

the front ones work just fine no matter whats plugged in the back.
I dont understand how i can fix the switch of my mic with a needle.
can you elaborate?

I mean mic socket - pink one near green speaker out socket. It have contacts in form of small metal strips inside. When socket is free, one of output strips usually is connected to common ground. That tell motherboard that socket is not used. Seems it became loose and does not contact anymore when microphone connector is not in socket. You must bend it back.
