I have a mother Intel D945PLrn series.

It has built in sound card, which is a high definition sound card. But the mic recording quality is very bad, scratchy the sound and poor quality, very low

I have tried getting help from Intel but many suggested method doesn't work;

Update driver and BIOS - doesn't solve the problem
Audio properties setting - I have followed the manual instruction, exactly. It doesn't work

Its normal output basically is normal, although it is called HD sound but it sounds like normal to my headphone. however, it just has recording problem, as mentioned above.

Please help on this. I just bought the motherboard not longer, I assume the motherboard is not damage, anyone using HD sound card also having the same problem of using mic? please give ur comments thx..

Hmmm...what kind of mic are you using? Part of the problem might be if you're using a mic that's not noise cancelling. Noise cancelling will "block" (or not record) some of the lower ambient sounds around you. The static that you're hearing might actually be the fan(s) on your computer. Seems unrealistic, but yes, it could be it.

Also, make sure that you're using a mic that is plugged in directly to your motherboard, and not one that's plugged into a USB port. A USB mic will use digital drivers to run it that is different than those of your motherboard.

Also, a cheap mic will cause this problem, too :thumbsup:

Hope this helps!

My mic is connected to the "rear pink jack"

The headphone is AVF (branded) headphone...

I'm suspecting Intel MOtherboard manufacturing problem..... or ? because I've seen one with the same series of motherboard have the same problem... How could it be?

The setting, all done correctly... until now, almost a month... contacting intel still couldn't found a solution to it.... wonder... wonder should i change to other motherboard??

Like stevealmighty said, a cheap mic will cause this. Or a defective mic. It is not likely a defect in the mobo. At least that is not the first thing to check. Change the mic to a KNOWN good mic and try again.

Try changing the battery in the mic - even if its new.
If the problem persists, try another mic.

Do you have a "sound effect" icon on your taskbar? If so, click on it and see if there are controls you can adjust.

If you do not have one there make sure you installed all the software that came with your motherboard.

According to Intel Support for the D945PLrn you should have software named Intel Audio Studio included. Is it installed?
Have you used it to set the controls for your mic?
If you do not have it, you can download it as well as the updated audio driver here:
http://support.intel.com/design/motherbd/software/ias/

Go through all the audio devices and their troubleshooters in your device manager - update drivers where applicable.

I've tested with many mic... all the mic function extremely well in other pc, elsewhere, this pc not, especially pc with "Intel D945Plrn Motherboard"

Intel Audio Studio..... All the software, all installed... BIOS... driver ... all updated...
go through all things...

The mic works but.... sound is very scratchy, captured voice is very poor, the mic input volume is very low.. although i put it to maximum....

I have contacted Intel..... after giving so many "methods" eventually doesn't completely solve the problem.
Now haven't gotten a reply from Intel since the last mail.

Thanks for all the suggestion so far... If anyone does use "Intel D945Plrn Motherboard series" please help me check the mic input... let me noe. post here. Or if u have any friends use this series of motherboard please pass this info.. thanks

Now I have found 1 person using the same Intel D945Plrn Motherboard have the same problem. Including me will be 2 person having the same problem with the same motherboard

Perhaps this motherboard just doesn't do a good job in this area. Perhaps you should invest in a good sound card as this would solve the issue, assuming that the issue is with the motherboard.

For what it's worth I found this information on the Intel site:

http://support.intel.com/support/motherboa...-020642.htm#mic

If you are experiencing problems when recording audio from a microphone plugged into the rear microphone port:

1. Update to the latest audio driver for your desktop board from Intel's Download Center.

2. Ensure you've selected the rear panel microphone jack as the default record device:

a. Click Start > Control Panel > Sound and Audio Devices.
b. Go to the Audio tab.
c. Set the Sound Recording Default Device to Realtek HD Audio rear input.
d. Click OK.

Actually I have seen that..... it is no longer no setting problem,

Now I change a motherboard, from D945Plrn to D945GNTL both are having sigmatel audio as default driver, .... however, the mic input sound really noisy..... too much noise than proper captured voice.

I'm thinking to disable on board sound card, to use the old model external c-media sound card. Because high definition audio...... I'm really really dismay with the mic input problem.... it just can't be solved. I have tried many many mic..... it still the same...

Newayz.... another problem I found on my pc, the sound hardware test, it ends up with error 0x8000405 dvp.exe is not installed... etc... I have checked up ... search intensively... on this... but to no vails. Some said change registry.....tweaking... zzz i've tried... but there is one "alternative method" which is to open the task manager at the same time, close the "additional dvp.exe" that was running before the error occurs...

I'm disappointed with these...... anyone use Intel Motherboard which High Definition Audio? Mic input? Please give me a guide. Help me..... help me on these.. :thumbsup:
