I just purchased an Asus A8N32-Sli Deluxe Motherboard which of course uses the Realtek Onboard AC'97 sound. The driver on the Motherboard disk is the same driver on Asus's website.

Anyway, I am getting a lot of noise Interference and I am kind of at a loss what is causing the problem.

1. I thought it may have been the chasiss Fans, so I bought some better one's and replaced - No help
2. I moved my clock, and cable modem off the desk - no help
3. I plugged the Surge Protector into another wall outlet - no help

The only thing I can think it may be is the Power Supply. I am using an Antec 450 Smart Power. Could this be the issue? Is it possible that the sound problem may be caused by the Power Supply?

It sounds like a low level static. Kind of like a low, but not heavy, popping sound, like you might hear on an old vinyl record.

I hear it more when the HDD is working but when I click on an Icon to open a program is disappears for a sec, but once the program is open is returns.

I did re-install the drivers, but it didn't help. It's not super annoying, but I write a lot of music through fruity loops and my PCI Midi card and Adobe Audtion picks up that background static noise at a very low level.

Try plugging the power for your speakers into a different power source( wall socket or power bar) than the pc is pluged into. It solved my interference problem with my soundstorm onboard sound.

try running a earth (ground) cable from your PSU to you mobo,
Its caused by the powerflow, you may also want to spread the spectrum as well.

Well, I have had the same problem over the course of two nforce2 and 3 based rigs. The nforce2 had the Realtek ALC650, and it had the same problem your board has. But, the nforce3 (I use it right now) has ok sound, using the ALC850. When I say "ok", I really mean "meh", but it worked. Only thing I can figure is that some boards just give out more interference then others, or that the sound chips themselves have different amounts of shielding. My advice to you is to go to majorgeeks.com and grab the latest Realtek driver kit (it supports like 12+ ALC soundchips chips, so your's is most likely there) just so we can rule out a driver problem. But, my ultimate advice to you is to bite the bullet and buy a soundcard.

The Soundblaster X-FI Xtreme Music is just about the best sound chip for the money. But if $125+ for a soundcard is too steep, the Audigy 2 and Audigy 4 can be bought for between $50 and $80. I own the Audigy 4 ($80 at Best Buy) and let me tell you, the difference is huge. The sound quality of everything is very good. I need better speakers now, lol. In-game performance is also better. The ALC had minor stutter and jerkyness in games like Call of Duty 2 and BF2. All of that crap went bye bye with the Audigy 4. Plus I can use EAX effects and hardware accelerated sound now. Thumbs up!!!

The microphone tab in the Volume Control, is it off? I know it sounds dumb, but when I turn my mic on, a lot of noise comes thru the speakers and it's really annoying. It's specially very noticeable when the volume is really high.

Gary,

From reading the title i can give you a answer to the problem i was getting with regards to interference.

I had the same prob and it was my monitor causing it, makes sure the monitor isnt near leads or
speaker wire.

Hope that helps.

Quick test to find out if it's speaker intererance or sound card.

Unplu the speakers and plug in a set of headphones - if you still get intrferance, it's the card - if not, it's the speakers.

Not a bad thing if it's the speakers - it could simply be that they are too close to a cause of static - wires, monitors etc...

Hope this assists, Good luck.

I unplugged the speakers, hooked up a set of headphones and the static is still there.

Moved the power cord for the speakers to a new outlet... same problem.

Monitor is LCD and sits 3 ft away from tower.

Never had the issue when i had a via chipset on my old K8v-Se deluxe system, but no biggie I was going to get a new Sound Card eventually so I could hook up my Yamaha Studio Monitors.

The only thing that sucks is I am in the middle of writing a score to a Mini DV horror film I have been shooting since summer 05, and trying to do ADR, and score the film makes it a pain in the a$$.

I am glad there is a community like this where people get together to help someone out. Thanks for all the advice. I am gonna buy a new sound card if that doesn't fix it I am gonna pack up the motherboard and exchange for a new one.

Ok so I have been through several forums, and before trying much else, I just fixed my problem. I am running off the onboard sound on my A8N32-sli, and had the same feedback, and interference at higher volumes. I was able to hear noise prodused from the hard drive, and while doing anything with the mouse.

Anyway, I just went in the volume controls, and went into the properties for playback, and selected every option , like Side, Subwoofer, Front, Rear, Aux, Phoneline, and PC Speaker. Muting PC Speaker seemed to fix my problem, or atleast hide it, also muting Aux,and Line-In, seemed to make a very slight fuzz noise go away.

hope this works for you guys

I've experienced exactly the same problem with my Asus A8N32-SLI motherboard - i am using headphones and i was hearing noises in the right channel and when i was encreasing the volume some poping appeared on each step in the left channel. There were also other funny 'sound effects' when using the mouse buttons, on hdd activity and etc. I tried a lot things to fix that , beginning with change of different drivers , i disabled every onboard device which i can disable from the bios - lan, usb, raid.... all of them but nothing seemed to fix this problems. The solution came from muting some of the volume controls. When i mute "Line in" the noise from the right channel moves to the left and when i encrese or decrease the volume the popping effect in the left is lowered and it is almost unnoticeable but the noise from the right is now several times encreased in the left channel. Next thing is to mute "PC Speaker" control - now the noise is almost gone , there is absolutely no volume 'popping' effect but still able to hear some sound from the mouse in the right channel when left clicking. Step 3 - mute "Microphone" - a few times lowered level of the noise and finally mute "AUX" - now the noise in the left is almost unhearable and no mouse clicking sound in the right.

It's your powersupply. The ASUS A8N-SLI series of motherboards have issues upon issues with Antec powersupplies, and seeming as your powersupply is from Antec I suggest you grab a completely different powersupply as I believe this will cure your problems.

Removing parts from a PC fixes problems?

BAWHAHA I was having the same problem, after reading all the troubleshooting i found one that hit the spot, muting the line in/aux/mic. what i found was muting PC speaker (as noted in the post) lowered the feedback by alot but ripping the speaker out of the case fixed it real good. (evil laugh) that noise was almost driving me to the brink of insanity so to no suprise i ripped that sucker out and threw it outside, stomped on it and kicked it down the street.

Simon has it right:

This issue seemed to start for me after a BIOS upgrade.

Windows XP: Open volume control>Options>properties>show "PC Speaker" control> go and mute the PC speaker.

I was having major interference and this worked 100% for me.

PS
That replace power supply thing was lame by the way...dont believe everything you read on the Internet.

Hey they are right. Mute the PC Speaker. I wrote a new driver to fix the problem automatically. Here is the download:

You have to manually install the driver using the device manager.

I tried Simon Ehrlich's advice about muting the PC speaker and it instantly made a differance.
I can _barely_ hear a _very_ faint humming in the background, but I have super hearing anyway :]

I am going to try mute everything not needed, but the PC speaker was the main villan for me, thanks!

Hi guys,

I have just solved my popping/clicking problem ...

SETUP:
RS400-A Intel chip based Pentium Motherboard
CPU Pentium P4 2.8Ghz
AC'97 onboard audio (only)

PROBLEM:
I had the odd pop/click come through the speakers while playing some housey tunes ... basically playing with Acid or Reason gave the same results (i.e any audio basically) ... it really wound me up ... it wasn't continuous ... it popped randomly at intervals of a few seconds ...

SOLUTION:
I just went and got the latest drivers (June 2006) from download.com (see below) and installed them ... I couldn't find these on Realtek's site though ...

Now there's NOT a pop or click heard anymore ... so it WAS the drivers like someone said above ...

DRIVER SITE (for A.3.91 Drivers):
http://www.download.com/Realtek-AC-97-WDM-Driver-Windows-98-Me...68908.html

DRIVER SPECS:
When installed they update the AC'97 chipset to the following:

Driver Provider: Realtek Semiconductor Corp.
Driver Date: 22/07/2006
Driver Version: 5.10.0.6150 (alot newer than the older 5.10.0.5870 I previously had)

Hope this helps ...

cheers,
Gem
:o)
