UNSOLVED
The Official Front Panel Jacks Buzzing Thread
Folks,
First, a disclaimer -- I am
not a Dell employee. I am doing this for the betterment of the XPS Community. With that out of the way...
I've seen far too many threads speaking of buzzing noises when using the headphone / microphone jacks on the front of the XPS 720. As such, I am going to be proactive and try to get everyone to collect our information into one thread which may help Dell track down the issue.
There appears to be two categories of buzzing. Please try to identify which one you are experiencing.
Category 1: The buzzing is related to the LEDs
Some people have an issue that certain combinations of LED colors and brightness causes a buzzing noise. Generally, this buzzing is
not related to mouse scrolling, etc. This buzzing, though faint, is evident in the BIOS which clearly points to a hardware problem To determine if you suffer from this problem do the following:
1. Ensure the
Microphone Boost is turned on
2. Plug in a microphone into the front panel
3. Turn your volume above normal
4. Using Quickset or nTune, adjust the LED colors and/or the brightness
5. If the pitch/tone and/or volume of the buzz fluctuates with the changes you call into
at least category 1.
Category 2: Everyone else
It seems many people have complained about buzzing caused by a variety of things, though mouse scrolling is a common theme. Since the LED is a single item that has caused buzzing for some, at this time it has been set as its own category. If new trends emerge, I may create additional categories.
So, here's what I am asking. If you are experiencing a buzzing noise when you use the front panel headphone / microphone jack on your XPS 720 (or XPS 700/710 with the upgraded motherboard)
please post in this thread. Please include the following:
- System Model (XPS 720 [Red / Black], 720 H2C, 700/710 w/ Upgrade)
- BIOS Version
- Operating System (XP MCE, Vista, etc)
- Sound Card (X-fi (D), On-board, etc)
- Any unsuccessful or successful fixes you have found
- System ship-date
- Mouse Make/Model & Connection type (USB Wired, PS/2, Wireless[Bluetooth / Other])
- Headphone Make/Model
To mirror DCF suggestions,
DO NOT POST YOUR SERVICE TAG. If Dell wishes to collect service tags, a moderator will handle that through PM. I would respectfully ask that this thread
NOT BE USED FOR DELL BASHING. Feel free to voice your frustrations, but do so in a constructive way.
-Cade

I am under Category 2
When headphones are connected to the 720’s front I/O panel, there is a noticeable electronic 'buzz' whenever I scroll a webpage/folder/document with the mouse (connected via USB). When the connecting cable is removed and the headphones plug directly into the card (or into an external jack i.e. speakers), there is no 'buzz' noise.
- System Model XPS 700 Formula Red w/ Upgrade
- BIOS: A03
- Operating System: XP MCE

- Any unsuccessful or successful fixes you have found
*disabling onboard audio,

*turning off LED lights,

Madparade7 said his service technician diagnosed the problem as a faulty Intel ICH controller on the M/B. He is being shipped a new board to see if that corrects the problem.

All,
Everyone should be adding the service tag number into your private profile.

Category 1 for me.I get popping out of the speakers whenever the LEDs change. So if I use the WMP plug-in, I get heavy popping, and if I just change the colors it makes the speakers pop also.1654

Catergory 1and 2I just got the new mb, so I'll try it out. I have plugged into the card directly in the back, and it works great, the problem is that the front should work. We paid for a machine that works properly, and thats what we should have. A Dell tech told me on one of my first calls " why dont you just use the back then?" that really ticked me off and this guy got an earful. I wonder how many people have had this problem. The intel ICH controller issue was found when we tried to run diagnostics on my machine, and we could not run the tests from bios , or from disc. The error message was " cannot complete diagnostics no intel ICH controller was found" and the machine re-booted. The tech said this was a mobo problem, and perhaps replacing it would help. My buzzing is worst when the video card is under stress.. when I play any game or watch a video, any scrolling or panning makes the buzz change pitch, but is faintly there all the time. Anyways, it will be a couple days before I can replace the board, so I'll keep checking back until then.UPDATE--I tried messing around with the led's, when I turned off the front lights , the buzzing went away when the machine was idle , but was still there when gaming or watching a video.... more baffling stuff..

I don't appear to fall into either category and have no problems. I have the cable to the sound card routed from the front connector to the outside of the case just inside the door and on the outside of the cooler support bracket and then to the XFI.I am just wondering if the cable being routed too close to some electrically noisy component is part of the reason that this is being experienced by some of the folks. Another thought might be to try and determine which device is causing the electrical interference if indeed the cabling is the culprit. Unfortunately I can't think of any way to determine if it is the cable or something else.Ideas ???1654

CadeMetz; great thread you started here...At first I thought you started this thread for the 700 upgraders....but it appears that a few 720 buyers are chiming in as well.* So, I must say that Dell did a great job with my Beast... I have no issues with my soundnor any buzzing of any kinds using the front or rear panel. Lucky me. Kudos to Dell :smileyhappy:I do wish I had less heat and noise though, but this thing hums along just fine, and I am certain that Folding@Home running 24/7 has a lot to do with the heat.Peace763

Sorry, the only effect I had with the cable is removing it. My tech and I have tried different ways of routing it around the box with no success.
