The old motherboard has been replaced with a new case, but the front panel microphone can t be used,

You know how to define the pins of the 2x5 socket for audio. Cut off the thread that is connected to it, leaving 6 and 10 a little bit, connecting the 6 left on 5, and connecting the 10 left on 9 (the front panel can be used, but there will still be sound behind the headphones plugged in in front).

Mine is also an old motherboard.,Bought a case with an HD panel.,It's AC97 written on the east of X.,It's HD when you send it.,Trouble is dead.。

I've encountered similar problems before, but I'm an old case and a new motherboard, and it took me a long time to find out that the wiring was wrong!! Check it out.

Drawing inferences can be solved, I hope it will help you!!

After changing the chassis or changing the motherboard, because it is not the original, there will always be some small problems in the audio, it is difficult to adjust, you can accommodate the use of it, and I have a new one that is also like this.

The cable is not plugged in, you look for the manual of your motherboard and see how to plug it in.

Connection: PW=Power SW (the front is the motherboard, the back is the chassis, the same below), there are positive and negative poles on this motherboard, and the chassis does not.

res=reset sw, there is no need to distinguish between positive and negative poles;

PWR LED=Power LED, this positive and negative motherboard and chassis are marked, and they can be connected against each other;

HD= LED, the positive and negative poles are marked, and the corresponding can be;

speak=sperker, this is also positive and negative, and there is generally no need to distinguish between them;

It is a fool-proof interface, which can be directly accessed.

Check to see if the audio cable is connected incorrectly.

If all of the above are normal, check whether the panel line to the panel jack is normal...

Try the microphone jack plugged into the motherboard (behind the computer case) first, if you can, the microphone jack in front of the motherboard is not connected to the motherboard, open the case, unplug the cable, and plug it back in.

The microphone is connected to the pink jack, first of all, don't connect the wrong hole, if you connect it wrong, there will be no sound.

After connecting, open the voice software to test it, such as QQ, YY and other voice software can be tested.

If the front microphone interface is not good, it should be that the microphone interface in front of the case is not connected correctly or not plugged in properly, try to plug it in and unplug it again, and use the back interface if it is okay.

If you can't do both, you can re-drive the device or uninstall the driver of the sound card and reinstall it.

You can also adjust the settings of the small speaker in the lower right corner Right-click Recording device Double-click the microphone or dot attribute In the level, you can adjust the volume of the microphone and the microphone enhancement (this is appropriately adjusted, turn it up, some computers will have current sound) Select noise suppression and echo cancellation in the enhancement, and select this device in the listening system, you can hear your own voice (this normal use is not selected, some computers will be stuck or noisy).

Go to the Control Panel Audio Manager and see if the front audio jack is disabled, if not, and the front panel headphone jack has an output, then the microphone jack is broken, or the cable to the main unit is not connected correctly.

Check that the front panel audio cable is connected.

1.Open the Control Panel - Audio Clarity Audio Manager - Audio I 0 - there is a small wrench in the upper right corner to click - to disable the front panel detection on the hook.

2.The front panel jack cable in the host may have been sent, disassemble the main chassis to check it, pull it out and plug it back in.

3.Clean the jack with anhydrous alcohol dipped in a cotton swab.

If it doesn't work, check if the earphones are broken.

The front audio cable is not properly connected.

Plug it on the motherboard.

Some chassis may have an extension cable connected to the audio interface behind the console to be changed to front.

The data cable connecting the front audio of the case to the motherboard is not connected. You open the motherboard and see if you plug it in yourself. It is recommended not to answer if you will not.

The current front audio cables of the chassis have been designed to interface with each other. Look for the motherboard, there is an 8 missing stitch on the motherboard, one missing, one missing.

It should be that the line of the front socket is not plugged in properly!
