"I turned off the accelerating of my ssd, and what happened? Sound working perfectly, no crackling anymore." -- posted by Vykoria

Many 7720 and 5720 owners have reported a loud random hissing noise that lasts for 5 seconds to 5 minutes. The noise is associated with the units' power system. The solution for this issue is to replace hardware components.

Inspiron 1545 & 1750 -- Intel Rapid Storage Technology

For audio glitching in these 2 models, the main recommendation is to download and install the latest Intel Rapid Storage Technology driver directly from the Intel site. Dozens of owners have confirmed this. It also works for many but not all XPS 15 (L502x) and other Dell laptops. --  first posted by mao.tsetung

Go to

Go to that page and click on the link named "Intel Rapid Storage Technology (Intel RST) RAID driver". On  the next page, download the file named: "SetupRST.exe".  

Other solutions that worked for some Inspiron 1545 & 1750 owners:

> Go to Device Manager, find the Intel(R) ICH9M-E/M SATA AHCI Controller, right click, select Properties, driver tab, roll back driver. Roll back to an earlier version of the Intel Matrix Storage Manager,

> or download the earlier version

> Go  to Windows Services and disable Intel Matrix Storage Event Monitor. Or just set it to "manual" start up.

> Or just uninstall the Intel Matrix Storage Manager. Most people who don't use RAID do not need it.

Section 2

Models with Vista Pre-Installed



> Wireless. The most common problem in Vista  is choppy/skipping audio when the wireless is turned on. This is easy to diagnose just by turning off the wireless. Press Fn+F2 on the keyboard, or turn off the wireless switch if your model has one. If the wireless is causing your audio problems then you will notice at least a partial improvement when the wireless is off. Sometimes switching to a different brand of wireless card can fix this.

(Forum member kakendle was the first to note a connection between the glitching and wireless on 2-26-07.)


> Disabling the 802.11a band. Some wireless card models still feature the "a" band. If turning off the wireless (Fn+F2) lessens the choppy/skipping on your computer then disabling the "a" band is often a permanent fix if your card has that band. I don't have a list of which models have the "a" band and which don't. The Dell Wireless WLAN 1510 Half MiniCard (4322) N card has it.

 Go to Control Panel > Device Manager > expand Network Adapters > right click Dell Wireless (your model) > right click Properties > Advanced Tab > click "Disable Bands". In the drop-down list on the right labeled "Value" choose "Disable 802.11a". Click "OK".

 On some models you select the "b/g" bands instead of disabling the "a" band. On some models updating to the latest driver fixes this problem.


> Update Drivers. Most of the problems seemed to be caused by a poorly written driver causing excessive DPC latecy. The worst offenders are wireless and  video drivers. If your laptop came with Vista pre-installed then there are no new driver updates coming out anymore, but at least be sure to have the latest ones that are available.Some drivers are available from the vendors websites but for most of them you need to go to the Dell Drivers & Downloads Selection page and either select your Service Tag number in the left field, or in the right column select "Choose from a list of all Dell products", then click "Continue" and follow the links to your model and operating system.


> Vista Anti-Lag. This little utility program helps eliminate the wireless problem, but if the solutions above work then you don't need it. Forum member aleywwu explained it this way: "From what I understand, it somehow prevents your wireless card from looking for a new network every 3 seconds by 'optimizing' your card.  It's temporary, and you have to re-run it every time you restart your computer, but it has completely, albeit temporarily, solved my problem."  You can google for a download or use the link below to go to one site that has a download available.

> XP Anti-Lag. The XP equivalent to Vista Anti-Lag is to disable the Wireless Zero Configuration Service. Go to Start/Run and type "services.msc" (without quotes )then hit the 'Enter' key (or click 'ok'). The Services window will appear and you can disable the service. (Tip posted by AlienKay.)

> Power: reduced power can caused poor audio performance, so run the laptop on ac (mains) power while attempting fixes, not batteries.

> Disable All Power Management schemes. There can be multiple schemes on a laptop because they are intended to extend battery life. They can exist for the operating system, for the graphics card, for the audio, etc.

To disable Sigmatel power management , go to Start>Control Panel>Sigmatel Audio>Advanced and uncheck "enable  power management".

To disable IDT power management , go to Start>Control Panel>IDT Audio Control Panel>Advanced  power setting, etc.

To disable Realtek power management, go to the power management settings on the Advanced tab of the Realtek HD Audio Manager.

On some models you can turn off "Enable Dell Extended Battery Life" in the Battery Meter window. (Tip posted by cmespinoza.)

> Power Settings on Inspiron 1501 and other models with AMD Turon processor:  change power plan to "Power Saver" or "High Performance" rather than "Balanced". You can do the power plan change at Start>Control panel > Power option. (Tip posted by Japan 2ch on 4-10-07.)

> nVidia Powermizer Setting on Latitude D830 & E6400, Precision M4300 and other models: should have the Powermizer turned off. "The setting is configurable via the NVidia Control Panel.

The only option in the Mobile group is "Change Powermizer settings" and I disabled it there. I also adjusted my 3D settings for Performance (as opposed to Quality) in the 3D settings group, as that was a recurrent, associated suggestion in posts about Powermizer problems."

2. Performance > Intel SpeedStep > uncheck Enable Intel SpeedStep
3. Virtualization Support > check Enable VT for Direct I/O

> Latitude E6500 graphics driver w/Vista Ultimate SP1: "The video chip is the nVidia Quadro NVS 160M.  When I roll back my video driver from the A01 to the standard VGA driver in Vista, the popping and skipping are no longer apparent in music.  Of course, I lose some of the functionality offered by the nVidia driver.

> Latitude E6520 with chirping in headphones: "The noise occurs at all times on my Windows partition (at all times meaning regardless of power configuration), and only when power is disconnected and running on battery when booted in Linux.... I had BIOS A04 installed ... I updated to A05 and the problem persisted, so I updated to A17 (A05 was required to make the jump to A17). Now my headphones make the sound once on startup, and once on shutdown, with no chirping in between."  (Tip posted by justbinfishin on 2-17-14.)

 Other tips that were posted:

> Anitivirus. On a 1525 with Vista, forum member Oxceraniod found that crackling on his computer was caused by the PC-cillin Anti-Virus that came with it. The solution was to exit from the program on the taskbar. Another poster thought his AVG antivirus contributed to the problem.  Forum member mgh0815 with a Studio 1555 wrote that removing the pre-installed CA Associates antivirus cured a buzzing noise and solved a problem with awakening from sleep mode.

> Set BIOS sound level to bypass: "I went into the BIOS and made sure that the HDD sound level was set to 'Bypass'. Usually, there are three options in the Dell BIOS's: Bypass, Quiet, and Performance. Even if your drive is set to 'Bypass', set it to 'Quiet', reboot into windows, and then set it back to 'Bypass'."

> Registry edit for M1330 and Inspiron 1720 with the nVidia 8400M GS video adapter. Open the Registry editor and navigate to

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Video\{**unique to you for nvidia**}\0000\

find PerfLevelSrc and change it from 0x3333 to 0x3332.  (Tip posted by stopgap on 12-21-08.)

> Configure
XPS M1710 for line-in. Plug a mic or headphones into the mic/line-in port on the laptop and when the pop-up box appears asking you how you would like to configure the port, choose Line-In. Doing so might resolve a problem with clicking, hissing, crackling and humming. (Tip posted by encrypter on 8-24-07.)

> XPS M1730 w/Vista tweaks:  Go to Start>Run and type msconfig and click OK. Then under "Startup" tab disable IDT Audio. Under the "Services" tab disable Andrea ST Filters Service and Sigmatel Audio Service. (Tip posted by noetzelmann.)

> XPS M1730 w/Vista: "Locate these two programs in the windows control panel/software and un-install them: Advanced Audio FX & Advanced Video FX." (Tip posted by noetzelmann.)

> Lower Volume on an Inspiron 1520. Maximum volume on this model can cause skipping or freezing. Lower the volume level to below 80% of max and compensate by raising volume of external speakers. (Tip posted by Eng.A7md  on 10-28-08.)

> Bad Power Adapter on Inspiron 1720. "I decided to unplug the laptop from the wall, and suddenly the skipping went away! Plugged it back in, and the skipping returned. Tried a different power supply, and the skipping is also seemingly gone. So it seems that the power adapter, at least in this case, was the problem." (Tip posted by TailsFurse).

> Aero Theme. Deactivating this theme might result in less noise. (Tip posted by FrancoisH on 2-2-08.)
Similarly, StereoHeathen got an improvement by ending the Desktop Window Manager (dwm.exe) which eliminated Aero.

> Disable Enhancements: Go to the Sound properties and under the "Enhancements" tab check "Disable all sound effects".

> Install the native Vista or 7 audio driver.  This is a basic driver that will lack some of the features of the regular (vendor's) driver, but it is a different driver and can improve or degrade the audio quality, or make no change. If you try this driver and still have audio glitching then you can rule the vendor's driver as the cause of the glitching. There are several ways to install the native driver:

> Go to Device Manager and uninstall the vendor's audio driver (Sigmatel, IDT, Realtek, or Conexant) driver and select the option to delete the files. When done, reboot.

> or Go to Start>Control Panel>Uninstall a Program. Find the vendor's audio driver then right click on it and uninstall it. When you reboot the computer Windows will install its native audio driver. Check that it is installed by going to the Sounds properties. If it says "High Definition Audio Device" on any of the tabs then it is the native driver. If it says "Vendor's Name High Definition Audio" then it is still an the vendor's driver, so repeat the procedure. (Windows will keep installing the vendor's drivers until all that have been downloaded are removed.)

> or  Browse to c:\dell\drivers\
Expand all folders and sub-folders there. Delete all folders that have a sub-folder named "WDM". Those will be the audio driver folders and it is safe to delete them. If they are not deleted Windows will re-use them to build the audio driver.

> or follow these 10 steps:

1. Open the Device Manager (type devmgmt.msc in the search box and hit Enter).
2. Expand the "Sound, video & game controllers" and right click on the vendor's audio driver which will be one of these:

  • Realtek High Definition Audio
  • IDT High Definition Audio Codec
  • Conexant High Definition Audio
  • Conexant SmartAudio HD
  • Sigmatel High Definition Audio Codec

3. Select to "Update Driver Software".
4. Click on "Browse my computer for driver software".
5. Click "Let me pick from a list of drivers on my computer".
6. Put a check in the box "Show compatible hardware" if not already checked.
7. In the list of devices, click "High Definition Audio" (the native driver).
8. Click "Next".
9. On the Update Driver Warning box, click "Yes" (install the driver).
10. Restart the laptop if prompted. If not prompted, then no need to restart.
[To get back to the vendor's driver, do it again but reverse the names in steps 1 and 6.]

Older Laptops That Started Having Audio Noise Over Time


 > Check for Ultra DMA mode on the IDE drives. [Note: this is for older laptops. Newer ones have SATA drives.] For several reasons the IDE hard drive or cd/dvd drive can stop operating in DMA mode and start using PIO mode. In PIO mode there can be crackling, popping and stuttering, and possibly generally sluggish performance. To check:

1. Go into the 'Device Manager' (in XP the path is: Start>Control Panel>System>Hardware>Device Manager).
2. Click the + sign next to 'IDE ATA/ATAPI controllers'.
3. Right click on 'Primary IDE Channel'.
4. Select 'Properties'.
5. Select the 'Advanced Settings' tab.
6. Check that the 'Current Transfer Mode' says Ultra DMA. If it says PIO then use the 'Transfer Mode' dropdown box to select for 'DMA if available'. If you can't make the change in the dropdown box then it must be done in the Registry. See the "Note" below.
7. Click 'Ok' to save your changes, or 'Cancel' to exit the Properties if you made no changes.
8. Next check the optical drive (CD/DVD). Right click on the 'Secondary IDE Channel' and repeat steps 4 through 7.

Note: If you get to step 6 and find you cannot make changes in the dropdown box, go to

They have a little script program to reset to DMA mode. Click on the link in their 1st step. (Note: for best results use Internet Explorer when executing the vbs script in Step 1). Read the instructions in their steps 2-5 and then run their program. It makes edits to your Windows Registry to try to reset the drive(s) back to using DMA mode. If you want to know exactly what the program does, scroll down to "Re-enable DMA using the Registry Editor" for the full explanation.

The rest of their article describes the problem in great detail and discusses possible causes and solutions for it. You don't need to read the entire article unless running their program doesn't get your drives back into DMA mode.

> Dell's PC Restore and Factory Image Restore. If your computer did not have any of the problems mentioned in this thread when it was brand new, then something has changed to cause the problem. In that case it might be easier for some people to return their computer to the exact condition it was in when new, instead of trying all of the possible fixes above. For others this should be regarded as only a last resort because it will wipe out any data and applications you have added and stored on the hard drive. In either case this will cure the problem -- but only on those computers that did not originally have the noise. If your computer did originally have the noise then it will still have it after you perform the restoration.

Dell's PC Restore for XP is an image of your original operating system in a hidden partition on the hard drive. It's like a normal reformat in that you have to save all of your data to removeable media, but it is different because it includes all of the original drivers, applications and configuration settings of the computer when it was new. Whatever was working when you got the computer will work after PC Restore, except for any hardware problems that have developed over time.

To use PC Restore you restart and press Ctrl + F11 during the restart process and it should take you to the "PC Restore" menu. Anything that doesn't work afterwards either wasn't working when the computer was shipped or is the result of hardware malfunction. For that reason PC Restore can serve as an excellent diagnostic tool for distinguishing between hardware and software problems.

On computers that were ordered with Vista, 7 or 8 pre-installed, Factory Image Restore does the same thing as PC Restore. To use it:

1. Restart the computer.
2. As the computer restarts, press F8 until the Advanced Boot Options menu appears.
3. Press <Down Arrow> to select "Repair Your Computer" and then press <Enter>.
4. Specify the language and then click Next.
5. Log in as a user who has administrative credentials, and then click OK.
6. Click Dell Factory Image Restore.
7. In the Dell Factory Image Restore window, click Next.
8. Select the Yes, reformat hard drive and restore system software to factory condition checkbox.
9. Click Next. The computer is restored to the default factory configuration.
10. When the restore operation is completed, click Finish to restart the computer.

Note: If your hard drive has been replaced or if you have ever wiped your original hard drive clean of all partitions, then you will no longer have the option to restore to factory condition.


 > Updating the firmware for a TS-L462C Cd rom/burner to version DE07 chops up the audio when not playing a cd, because that firmware revision is defective. To diagnose, place a commercial music cd in the drive (not a homemade mp3 or data cd -- just use a store bought cd or a copy of one). If the problem lessens then read this thread for instructions. Note that using PC Restore or Factory Image Restore (above) will not fix bad firmware.

To see if you have a TS-L462C open Audio Properties (right click on the volume icon on the taskbar and click 'adjust audio properties', or go through the Control Panel/Sounds & Audio Devices Properties). Select the Hardware tab. Look for DVD/CDROM in the device column. The name of the drive should be there.

To see which firmware revision you have,

 In Windows Vista go to Start then right click on My Computer and select the Manage option.
Expand Storage, then double-click Disk Management.
Right click on the CD-ROM/R/RW and choose Properties>Details.
Select Hardware Ids from the Property drop-down menu.
Your firmware version is located to the right of the of your drive name, usually combination of numbers and letters.

In Windows XP go to Start then right click on My Computer and select the Manage option
Expand Storage, then expand Removable Storage and then expand Libraries.
Right click on your optical drive name and choose Properties>Device Information. The Revision is your firmware #.

Windows Media Player Skipping

 If you have an old version of Windows Media Player

> Disable Enhancements. If you experience skipping near the end of a song while using Windows Media Player in Vista, check the box that is labeled "Disable all enhancements". Go to the Sound properties and under the "Enhancements" tab check "Disable all sound effects". Just shutting off the enhancements individually won't work. The obvious drawback is that you lose the enhancements. (Tip posted by smittyofdhs on 2-20-07)

 > Disable Visualizations. You might get some improvement by disabling all visualizations under the Now Playing tab of Windows Media Player. (Tip posted by hovaslash on 2-28-07.)

> Crossfading and Auto Volume Leveling. Along the same lines, you might get some improvement by disabling Crossfading and Auto Volume Leveling. (Tip posted by wewake17 on 4-12-07.)

> Lightfx Plugins. Similarly, Dell tech support suggested removing the lightfx plugins completely. (Reported by forum member fhwfhi on 2-13-08.)



Section 5

Buzzing noise starting around 2-11-15:


The symptoms are a buzzing noise that occurs every 60 seconds while listening to audio or video, perhaps also increased fan noise and stuttering. The main solution is to remove Dell SupportAssist and Dell SupportAgent. However that does not work for everyone. Here are all of the solutions that have been offered to deal with 2-11-15 noise issue:


Go into Control Panel>Programs & Features and look for Dell SupportAssist and Dell Support Agent and remove both. -- wildmanyeah was the first to post this solution

"It seems that the real problem is with Dell Data Vault and Dell Data Vault Wizard. To solve this is necessary to shut down them in the Task Manager and then set up so that the service does not start again when you Windows start up." -- vinilara

"Seems like disabling the Dell Data Vault ...helped for me too. I could not stop it in the Task Manager but turned off on the start up and that was enough." -- wmc326

"The cpu usage of delldatavault.exe spikes when the "bzzzt" happens and killing the process fixed the problem with no obvious side affects. The DellDataVault service collects performance data, so I didn't want to uninstall or delete it. I just kill the process whenever I want to listen to audio". -- dgm741

[Type task manager into the Windows search box. Click on the "Processes" tab. Select the Dell DataVault process and click the "End Process" button.]

"1) UNINSTALL Dell Support Assist and Agent from your programs. 2) Go to msconfig [type msconfig into the Windows search box] and go to Services (you cannot remove them from the task manager and they are not in the startup programs)  - disable both Dell Data Vault programs from there." -- jld88

"Create a System Restore Point....Full export [backup] of the Registry ...  Open Task Manager and click on processes tab.... Right-click on DellSystemDetect and select Open File Location... Delete the entire folder where that file lives.... Click Start button and search for "regedit" - open it up....Search for (Ctrl - F) dellsystemdetect (not case sensitive), and remove every instance of it, including Keys, Values & Data.... Do a cold reboot." -- IvoryStrat

"Uninstalling the Dell Support programs as you did should have automatically removed two system devices, Dell Diag Control Device (which is the culprit) and Dell System Analyzer Control Device. Go to the Device Manager (from the Control Panel) and look for these under System devices. If they are still there, disable them...." -- RandyGibbons


"When I followed Randy's post about going into Device Manager and looking under System Devices for remaining entries for Dell Assist, I found that BOTH of the items Randy pointed out were still in the list - although I had deleted the programs. I followed what Randy indicated - disabling the two items - and have had no problems. .... I had to also uninstall Dell Data Safe ... It is somewhat hard to delete Data Safe ... You need to go to the services.msc from the start menu [type services.msc into the Windows search box] and  then right click on the Data Safe running entries - to stop them and then to make sure they do not launch automatically. Then you can delete Data Safe using Windows Explorer in the Program Files directory." -- StvLwyer

" ... as some people said uninstalling this [Dell SupportAssist] did not fix the audio/video problem. What I did not realize was that delldatavault.exe runs as a service in the background....Completely disabling the service altogether, has finally relieved my migraine..".-- toolrox

"My fix ... was to go into the services panel and stop the ( DellDataVault service ) and ( DellDataVault Wiz service )....I did not have to remove any software." -- roestman


Dell has created a "hotfix" for the problems related to the SupportAssist update of February 12, 2015. It might fix the problem for those who do not want to remove the utility. The following was posted by Dell Terry_B:

Go here
* Under the "End User" tab, click "SupportAssist for PCs and tablets"
* Download/save the file "aulauncher.exe" to your windows desktop

* Run the file
* Reboot when done
* Download/save the hotfix from this share:
* Double-click the exe file. You should get a message saying “Successfully applied the hotfix, please reboot your system for the changes to take effect” -- Dell_Terry B

Please do not reply in this thread which is a FAQ.

If you have comments or questions please start a new thread or send me a private message. I will post additional tips & solutions when I get them.

Thanks, I appreciate it.

RE: Choppy/Skipping Audio by NukiI did all the things as I browse the net. Nothing is changes. My IDT Audio still buzzing and the volume decrease by it self. On 5.1 test sound, all speaker is good except center and sub. Usually in Temp folder, theres always FX Engine file. That file is gone. Maybe that's the main issue.
