Sound interference?

[dunno99]

Hey guys,

I'm in the market looking for a new Z77 motherboard. One of the big annoyances with my current Gigabyte P35-DS4 is that I can literally hear the interference of devices on my machine. For example, if I move my mouse, I can hear a monotonic frequency on my earphones. When I click, it's similar. When my video card is spinning up to play a game, the same thing happens. I'm pretty sure this is a cross-talk/interference issue. And since it's sensitive to just my mouse moving, I don't think it's a wall socket issue.

Now, my question is, given that this happens on a Realtek 889A (the one in the P35-DS4, I believe) and/or the Gigabyte board's layout, what's everyone's experience on the newest crop of Gigabyte and Asus Z77 motherboards with Realtek chips and/or board layout? I'm looking at the Realtek 898 (people have been clamoring how good they are). I've also been looking at the Asus Maximus V Gene and its supposedly isolated onboard sound, as well as waiting for the Maximus V Formula's reviews. Anyone have impressions/predictions for the latter as well?

Thanks

Likely an IRQ conflict, try moving things around and see if that helps.

On the hardware side, I only have one card installed on that motherboard, and it's the graphics card...so I don't know if it's IRQ conflict. On the software side, if it's IRQ conflict, wouldn't that mean only a thing or two would cause the interference to manifest, not, well, everything?

As an aside, given my usage patterns (which is that I don't put many add-in boards), I'm thinking about saving on e-waste and just going for the smaller Gene.

Thats a shared ground on your front panel audio that is causing the interference, not the motherboard. Most inexpensive cases have this issue, such as my Bitfenix merc Alpha. Plug in an external HDD to the front panel while listening into your headphones, you will hear it spin up through the headphones.

Are you plugging in your earphones through the back or using the front panels?
If its the common ground problem with the front panel as mentioned above then its not a problem with Realtek/motherboard and using a discrete soundcard or getting a more expensive mb will not solve the issue. You'll have to use the rear ports, modify your front panel pcb (dremel/solder). Or get a soundcard with its own front panel box.

Some cases quite some time back supplied doughnut shaped magnets(?) to loop around front panel wires to reduce rfi. I don't know if that worked.

I think this is 100% correct.

I think this is 100% correct.

Tried both the front and the back. Without and without extension. Different earphones/speakers. Same thing.

I am having the same issue. The noise seems to be coming out of the back of the case by the USB ports. All motherboard screws are tight. I also get the noise over the headphones when I plug them into the front of the case, but my case is not cheep it is a Thermaltake level 10 GT case. My motherboard is the Gigabyte GA-970A-UD3. I have tried everything that I can think of and all my drivers are updated. The noise even happens when I am in the BIOS using my usb keyboard. I am having Newegg send me the same board to see if it's just a bad motherboard.

I had a similar problem some years ago, what I narrowed it down to was interference from the mainboard CD-AUX input. You might try going to control panel -> sound -> recording and check that any line in and microphone input are both disabled and the recording volume is turned all the way down. It might not work in your case but it's worth a try...

Thank you I did try that but I didn't have any luck.

Ok so I switched the motherboard and come to find out the noise is coming from the power supply. Power Supply is an OCZ Fatal1ty 750w.

A joke ?
IRQ conflict is not possiable with ACPI MB and XP or higher!
Most likely you having a R.F. leak. Prob a bad choke.
Cheap soloution get a Sound Card. 99% chances it will filter out those leak sound.
Its rare for P/S to make that sound.
It could be you having very very BAD A/C current.

 

[haaiamerica]

update your sound device drivers for your main board.

Tried both the front and the back. Without and without extension. Different earphones/speakers. Same thing.

Then try downloading newer sound drivers. If that doesn't work, buy a cheap sound card (like an ASUS Xonar DG), it should definitely solve the problem.

I had a weird faint crackling static sound when moving or looking around in some games on my last pc. it happened with headphones front or back and with sound card or onboard sound.

 

[Mir96TA]

I am telling you; its hardware issue. You having R.F. leak. Prob a bad choke.
Most of the time it is M.B.

 

[ZeroRift]

This definitely sounds like a hardware issue. Some things you can try to verify:

1) Get some el-cheapo USB (digital) headphones and see if the sound is still there.
2) Test with a discreet card to see if there's a difference (may still hear it if you have a bad choke)
3) Try plugging your headphones into the back and your mouse into the front panel. This may resolve the cross talk issue depending on which component is at fault (kindof a long shot, but it might work).
4) Try plugging your headphones into a pair of speakers. Their built-in receiver may filter out the cross-talk if you're very lucky.

As for other boards: I have a very low opinion of on-board (built in) audio. I've never had a problem like this on a discreet card. I've personally never used a Xonar card, but I hear they are pretty competitive with other discreet cards.

 

[diecast17]

Swapped out the Power Supply and I can 100% say for sure now that it was the power supply!!!!!

 

[futurefields]

It's the ground problem. All you have to do is crack open the front panel, pull out the white wire coming from the usb header (ground wire) and ground it to something else, I forget how. I might be wrong on the wire color though.

Lotta posts on this mothah-hutchin' thread.

I've never encountered this problem, but the advice already given seems to be "responsible" advice.

One board I had . . . probably over-promoted . . . Eh! "Strike" that . . . had problems with Creative SB X-Fi cards. And I HAD an X-Fi card . . . .

On the "discrete" versus motherboard sound question -- going back to that high-end LGA775 Asus board . . . that board and some (better) pretty decent mobos had been touted as having pretty good audio competitive with Creative. Some people I know may have been confused in their Sound Blaster/X-Fi worship: Creative Labs had bundled some excellent software with their cards, while what you got with the mobo was plain-vanilla-next-to-nuthin.

I chose to replace my 20-year-old stereo rig with a "Home Theater" receiver and speakers -- just so I could "integrate" my TV experience with my computer. And it's nice that the sound capabilities of the graphics card (for HDMI connection to an AV receiver) are discrete and separately manageable from my 5.1 Logitech speakers. I ALMOST spent money hoping to get a new sound card. I'm glad I didn't.

I'm more worried about these rumors in the news' "bidnis-pages" that "PC is obsolete." Well, since I don't travel much or even leave the house but for groceries etc. -- I don't need an I-Pad2 or even a laptop. And I just can't imagine running my Home Theater and home security system from either type of hardware . . . " . . . any mobile device . . . 'Beam me up, Scotty! . . . " yadayadayada. Keyboards for the E-trade baby . . .

Over-Clockers . . . Unite!

 

[bankster55]

might check in programs features to see if you have MSU (Marvel Storage Utility). Will do it fer sure on certain mobo.

 

[Lonbjerg]

I thought this was common knowlegede that onboard sound is shielded like a...sieve...

 

[bankster55]

maybe yes, maybe no
