Windows 7: xonar d2x sound card loud buzzing noise problem

I am using xonar d2x sound card and it has been good until recently when I played videos on youtube and games it gives a loud buzzing noise. Even sounds made by windows sound produces the loud buzzing noise. It also happens on sometimes when playing videos. Other than that it works fine. I tried to use realtek sound but can't find the driver on device manager, even after downloading & installing the drivers. I tried reinstalling my xonar sound driver but it didn't fix the problem. I reformatted my pc and installed the xonar sound card but the problem is still there. I then tried installing the update for it but my pc crash (blue screen with driver_IRQL_not_less_or_equal error). After restart, there's no audio output device detected. Device manager shows Marvell 91xx Config ATA device not installed.



I'm really frustrated now. Is there anyone that can help me? Thanks alot.

First, don't have two sound devices enabled, as that can cause conflicts.

Is the buzzing caused by something attached to the sound card? e.g. a "ground loop hum". Remove anything attached to the card and then just connect a headphone and see if you still get the buzzing. If its gone then what is attached to the card is causing the problem. If its still there the first step is to "reseat" the card (with the PC powered off, remove the sound card then reinstall making sure its fully and correctly seated).

I don't have 2 sound devices enabled. Only the xonar. Realtek can't be found.

I don't have any attachments to my sound card. I don't think its a ground loop hum. The buzzing sounds like distortion or kinda like the buzzing sound u get on the radio.
I did reseat my sound card before but it didn't solve the problem. Also I tried using a headphone to make sure my speaker isn't the problem but I still get the buzzing sound when using the headphone.

I'm guessing its a hardware problem?

Although it could be a problem with the sound card, that sounds like a bad connection. I do guitar amp repair so I come across similar noises at times.

Disconnect the front panel headphone/mic connection to the card and see if that makes any difference.

Disable all outputs/inputs you are not using or at least turn them all right down

Might do the trick

I don't think the panel can be disconnected. I'm really confused. Sometimes it works fine when playing music but sometimes it gives distortion noise. I decided to switch back to realtek back I can't find the driver of it.

Anyway thanks for the help fireberd. Appreciate it.

What do u mean inputs/outputs?

right click on speaker icon on taskbar
Go to "Audio devices" or "playback devices"(win 7 icon)
sub menu
"Playback" + "recording" + "communications"

mute or disable all the items you don't use or say "unplugged"

I'm trying to remember as I own a xonar (not being used at present) there should be access to another setting for adjusting 'latency' which might help

Whats wrong with latest asus drivers cos they keep them reasonably up to date - download them

Before you do that, clean your pc of realtek driver debris
install "driver cleaner"

Tried disabling all the other stuff that I don't use. Doesn't work. I just reformatted my pc so there shouldn't be any realtek driver stuff on it? To be safe I'll do a check on it. I did try to update the latest asus driver but I got a blue screen with driver_IRQL_not_less_or_equal error. And also, I have Marvell 91xx Config ATA device not installed showing up on device manager.

unload all asus soundcard stuff

Pull the soundcard out of slot

download and install all motherboard stuff in device manager with yellow query mark
Reinstall your graphic driver! restart
make sure all is ok in device manager

now reinstall soundcard in a different slot if available

make sure onboard sound is disabled in bios (pref. not on 'auto' choice)

install asus latest drivers

See now if it installs properly without blue-screening

After restarting your pc to embed drivers

Have you installed latest 9.0c directx file updates?

click search button on your pc after install (& restart)
type 'dxdiag' in "search progs & files" box at bottom
open dxdiagnostics
and go through the menus esp check sound
