xonar dgx crackling/hissing - Page 2

post #11 of 18
I don't think it's unheard of to have the slots on the motherboard go bad, but I don't think it's exactly common either.

It's really strange that you would have 2 that would have the same issue. I have no experience with the DGX, but I do have a DG and I haven't had any issues with it at all.

Have you double checked to make sure that the headphones are plugged all the way in?

The Front Panel connectors shouldn't have any effect, connected or disconnected.

Does the DGX require power? Some cards do.

Have you checked your device manager to see if there are any conflicts?

No conflicts on the device manager.
The Headphones are indeed plugged all the way in.
The card doesnt require extra power.

Silly question, its a PCI-Express card, that means it can be OK in any PCI-express slot, correct? It doesn't need one of the tiny short ones, right? The prongs on it are the two small ones, not the full length deal.

I have it plugged into a PCI-Express x16 slot.

It's a PCI-e x1 card, but PCI-e slots should all be backward compatible (you can put a x1 or x4 card in a x16 slot).

Yeah that's what I thought.

The only thing I can think of is the motherboard is causing interference somehow, or when the onboard audio died it effected something. It's been a great board but it's gotten heavy use for several years now.

Well just an update, I guess.

Swapped everything over to a brand-new M5A55FX Pro R2.0.

Same problem right off the bat.

So im just using the onboard sound.

I might be somewhat of a slowpoke here, but I googled around having the same problem with my DGX peice of crap. And while reading here I got mine to shut up! In the Xonar utilty, enable AEC (Aucustic Echo Cancelling). All the white noise and coil whine-like sound dissapeard - dead silent! Havn't tried it with mic headphones yet though. It's there to remove the noise your mic pics up from your speakers. So I guess you might have to fiddle with the slider a bit so it doesn't remove anything it shouldn't. It doesn't affect the silence though - how ever I drag the slider - the noise is gone.

Me guessing - the soundcard is a real piece of **** and has crosstalk on the PCB, or in the IC's themself. I don't even have a mic connected at the moment, so a feature adding filtering to the mic channel should really do nothing. But it does.

Yeah, very late to the party but I thought other people googling the topic might find this helpful. This problem started for me today on my DGX. My right channel suddenly started making lots of white noise, buzzing, and crackles. It changes depending on what the computer does, so it's crosstalk. Goes away when disabling "Headphones" in Xonar Audio Center and selecting "2 channels". (The AEC setting switches to 2 channels automatically while it's active - that is why it works.)

The thing is, it started right after a thunderstorm where there was one lightning strike really close by. My guess is that the headphone wire acted as an inductor and created a current spike that the headphone amp couldn't handle. From other people's stories it simply seems as if the headphone amp circuit on the Xonars is very sensitive. You can probably get the same effect by a small static discharge on the headphone cable/input; it burns the shielding circuits or something similar.

My headphones are not very powerful (Koss PortaPros) so the 2-channel setting works fine for me. But if you're looking for a solution other than that I think the only option is buying a new sound card.

I can attest to issue, as well. Within about 3 months of owning the Asus Xonar DGX, mine started this exact white noise/hissing/crackling/buzzing noise. It is predominant in the right channel, and as others have said, nothing seems to fix it. The buzz is much more vibrant when "Analog Out' in the Xonar Audio Center is set to 2 Speakers all the way to Front Panel 2 Speakers. Lucky for me, the Headphone setting produces the least amount of buzz.
  • The buzz correlates with my graphics card displaying brighter colors (e.g. white background on Google). Scrolling down emphasizes the crackling. There are MANY threads on the internet where people attribute it to interference from the graphics card... I'm not sure about this. Card worked perfectly for several months and moving it to a different PCI-e slot makes no difference.
  • As others have mentioned, using the Asus' drivers or the Unified drivers makes no difference.
  • My Acoustics Echo Cancellation setting is already off, but as TheManMachine pointed out, having it turned on makes it worse. Make sure this setting is off.

I've simply given up on finding a solution. I can't really hear the buzz during games, music, or movies (unless there is a lull in sound from the source) so it's not a dealbreaker...just really annoying. Asus is lucky this thing only goes for about $40.
