Xonar DG Problems

Jonnyk · 30 Jan 2011 at 21:55

I bought a Xonar DG sound card about 2 weeks ago, and in the last few days I have noticed an electrical "buzzing" coming from it. The strange bit is that it is only coming form the back panel ports.

I have tried a few things to try and see what the problem is. all possible combinations of graphics card and sound card in the PCI-E/PCI slots, no change. Plugging my speakers into the front panel results in no buzzing, and plugging my headphones into the back panel does have buzzing, so it defiantly seems to be only a problem with the back panel.

I think i have narrowed down the problem to the graphics card, as when running graphics intensive tasks the buzzing get's louder. But also anything that results in the picture changing, moving a mouse, typing etc.

Does anyone have any ideas as to what might be causing this, as it's kinda annoying to say the least

Thanks.

Yeah, I did read about the 'dirty power' idea, I just found it strange that it only happens when using the back panel, because surely the same power is used for both the back and front panels?

Having thought about it a bit today, it did seem to start the noise only a few days ago, about the time I updated my gfx card drivers to 11.1. This seems too coincidental to not be worth a look. I'll roll back to 10.12 when I get home tonight and see if anything changes, although it seems like a strange thing to happen.

Instead of changing my gfx card drivers again, i just bought a new card, £200 gtx 480 was hard to pass by. I'm still having the same problems, i'm not sure what to do, at the moment I'm only using the front panel.

Any more ideas on what it could be?

card before was a saphire 5770, and the motherboard is a asus m4a785td, can't remember exactly which one but i think it might be a 'v-evo'.
