UR22 buzz/noise DirectX issue

Hello guys,

I just bought a brand new PC with a brand new UR22 :

Asus V77-A / Intel i5 3570k
Windows 7 64bits
Steinberg UR22
Yamaha HM50

Cubase is OK, it runs smoothly with pristine sound, UR22 is doing a great job for a low end sound itf. BUT… playing any game results in a constant noise/buzz out of my monitors. This buzz is pitched by any move of my USB mouse (kind of fun but irritating : i can’t play no more).

I tried COD Ghosts and Batman AO… same buzz. The only difference i see between Cubase and a game is the way the system access the sound itf : Cubase = ASIO ; Game = DirectX

Here are the steps i followed in order to solve my problem :

  • update UR22 drivers (up to date : 1.8.3)
  • update DirectX 11 (June 2010 version found on Clubic)
  • change sample size
  • deactivate HD audio chipset from my MB

Nothing worked and i feel stuck.

I seen there is a low freq noise on a few batches of UR22 but i checked my serial : its not included in the list of defectuous materials provided on steinberg website. Beside i don’t really have a low freq noise everytime but a mid freq buzz on directX programs.


Could someone help with this issue ?

Thanks a lot.

Hello,

Have a look here, maybe your directx version is not the right one for your OS

Hello ktofe,

Thx for this advice. I tried to update DirectX from Microsoft website but the installer told me nothing can be installed because my DirectX is up to date.

-_-

I have the same problem and in looking for a solution what I find suggest there is a usb ground loop problem. I have not tried any of the products that supposedly remove via isolation. But wonder shouldn’t such electronics to do this be part of the UR22?

Additionally using a USB to computer for the Yamaha PSR-S750 is as well noisy, perhaps more so. Meaning the PSR does not have the needed ground loop isolation either.

Tried a different cable running a different path and noise is reduced but still there
