Hi all,

I have bought the following parts:

Motherboard - Asus Z170-P
CPU - Intel Core i7 6700k
PSU - 750W FSP Raider
RAM - 2x4GB G-Skill DDR 4 Memory

I also have a Geforce GTX 970 along with the above.

I installed all the parts and everything works fine except for the sound.

Using the Realtek onboard sound, I get a lot of crackling when playing anything which involves sound. I also have an Asus Xonar DGX dedicated sound card which also suffers from the same problem, to a much lesser extent.

If I put the Xonar near the upper area of the motherboard (right above the VGA), it gets much worse. I am stumped because I cannot figure out what could be causing this. Things I tried:


  • Using the PC without the case
    Unplugging all USB ports
    Trying a different PSU
    Installed drivers
    Trying Linux Live CD

The only way to get clear sound is to use the monitor speakers via HDMI (even though it has some background buzzing).

Does anyone know what could be causing this?

Thanks!

After reading everything you have already tried all i've got is this -background buzzing sounds like a ground loop...basically electrical noise.. popping or crackling could be bad cables, the fact that it seems to get worse the higher up you install your card makes me think bad shielding on your board...
I'd say maybe try a different power outlet in your house .. also, try better quality cable.... if it persists then possibly just bad shielding on you board?

also, try disabling all sound enhancements

Thanks for the reply!

Sound enhancements are all disabled, tried different cables and got the same result.

It gets worse with increased activity on the other devices (especially the hard disk).

I can try another outlet but I think I am just going to have to purchase an external sound card.

I'd still try another outlet just to be sure but yeah it sounds like bad shielding or even a crap card.

I bough a sound blaster omni 5.1 model number sb1560 and I honestly love it..but my needs may be different from yours idk.

Weird thing is the card was working perfectly fine on my old motherboard and also I haven't heard any issues regarding this particular motherboard.

I tried another outlet but the result was exactly the same.

I will look into the sound card you mentioned as it seems I have no other choice as I cannot isolate the issue.

Thanks for trying to help!

So I purchased an Asus Xonar U3 external sound card and the problem is even worse!

At this point I gave up and just started using the VGA's audio as output which is very clean.

Hi,

Try this!
go to BIOS / AI Tweaker / AI Overclock, change XMP to Auto and all options under this to Auto also.

This fix all audio problems for me when high CPU or GPU loads.
