[Beginner] Reference Dell Audio and SD Realtek Audio Manager

Hello world!

A few days ago, I bought my first Dell: it's an Inspiron 15 3537. So far so good. Installed Windows 7 64 bit and some drivers, including ALC3223 Realtek High-Definition Audio Driver. Now, the sound is perfect when it's speakers, but all the times that no matter what sound plays on the helmet (the portable computer has a combo Jack), he is very strong and there is a unpleasant noise. If there is no sounds play, after a few seconds, the noise stops. (edit) The gentle sound remains the same regardless of the volume and does not grow stronger if the volume is turned up.

I tried to adjust things in the sound menu, searched for solutions online and my best bet would have been accessing the Realtek audio Manager.

But after installing the latest driver Realtek, I get only Audio from Dell, and it isn't much help. Looking for a Realtek in the control panel or in folders only leads to the Audio from Dell. Here, I discovered why the strange whistling sound in the headphones will stop when no sounds are played, but I can't find anything to make the noise go away:

What the Dell? While I hoped something like this (taken from the internet):

So, can someone tell me why my laptop is Dell Audio when I install Realtek driver? Can I "non-Dell' Realtek Audio Manager on my laptop? And suggestions to reduce the background noise in the headphones?

Hello. Dell and Realtek replaced the DD Realtek Audio Manager with Dell's Audio Manager on Dell laptops. I don't know why. The DD Realtek Audio Manager can provide a separate headphone and speakers, volume control while the Dell version can not. Several people have reported that even when they download & install a driver directly from Realtek site, Dell Manager returns. I do not know how to defeat that (I don't have Realtek on my laptop and not the one who has it posted a method).

You can use an online with the headphone volume control. My Latitude with IDT is not the problem of the headphone volume a lot of laptops from Realtek, but I use Koss control just because it's convenient. It's a short extension for headphones with a cursor of volume built in mitigation.

Regarding the drivers, Dell has only one for your model out for Win7. The only other drivers Realtek would be on the Realtek site. You can also use the native Windows audio driver. To switch to it from the Realtek, follow these steps:

1. open Device Manager (type devmgmt.msc in the start search box and press ENTER).
2. develop the 'audio controllers, video & game' and right click on "Realtek High Definition Audio".
3 Select this option to "Update driver software".
4. click on "Browse my computer for driver software".
5. click on "Let Me pick from a list of drivers on my computer".
6. put the "Show compatible hardware" check box if not already checked.
7. in the list of devices, click on 'High Definition Audio"(native driver).
8. click on "next".
9. in the update driver warning box, click 'Yes' (the driver).
10 restart the portable computer if you are prompted. If not invited, so no need to restart.
[To return to the Realtek driver, do it again but reverse the names in steps 1-6.]

If you still get the hissing or background noise with the native driver, then it is almost certainly in the material. If the noises disappear when you use the native driver, then they are caused by the driver from Realtek.

    Thank you

    With multiple VLANs, you need to use the general/Trunk mode. With the help of the info we have I made a diagram to help show the location of the switches and parameters on them. Obviously things can be different, such as PVID, IP address, VLAN ID etc are all customizable to your needs. But the page layout modes and the port will remain the same.

    STP will not fill the VLAN on the other switches. It's probably the GVRP feature it refers. With such a short race, it is more practical to manually add the VLAN. At least for the initial Setup, then once everything works enable GVRP to accommodate future expansion of VLAN.

    Hope this helps some.

  • Reference Dell backup and restore is unable to create a DVD of recovery on Windows 8

    Dear Dell,

    I am creating recovery discs "Dell backup and Recovery application" but when I was asked to insert the second DVD, the optical drive keeps rejecting DVD. The application will not continue to burn the second DVD and seems to be frozen. I tyied with different DVD brands/manufacturers and also-/ + r unfortunately. The question remains. I could find this 593906 article published 21-01 - 2013 (http://support.dell.com/support/topics/global.aspx/support/kcs/document?c=us&cs=19&docid=593906&doclang=en&l=en&s=dhs link). Although I did the updates, I'm still not able to create recovery discs!   File: after having inserted the Disc 3 application gives the message "Dbr.exe-" not found disk and stays there and rejects the DVD.  I spoke with the Greek team of Dell. I was told that warranty does not cover the support of sw even if my unit is less than a week. Furthermore, I learned that although "Dell backup and restore" application said THAT DELL is not actually a Dell product so they can't support. They my proposed to use the recovery of files from windows 7 place (which needs at least 8 DVD!). As you can understand it's a workaround and not a Solution.

    I hope that someone from Dell will consider the issue and to come back with a precise answer and a permanent solution.   (Model: inspiron 15 3521). Thank you

  • Reference Dell backup and restore - "an error occurred during the creation of the backup of the system"

    I have a Dell XPS-8700 running Windows 7.  I bought the Dell Backup and Recovery Premium Edition.

    I was able to create a backup bootable (hot spare), and I can create a backup of data on my external hard drive.  However, whenever I try to create a backup on my external hard drive system, after about three seconds in the process, he returned: "an error occurred during the creation of the backup of the system.

    How can I create a backup of the system?  Why I get this error?

    Thanks for all the info. My situation sounds very similar to yours.

    I removed using Add/REMOVE programs in the control panel DBR and he removed cleanly.

    V1.7.1.2 downloaded and executed new facility.

    When I ran, it was my premium license key so he had yet to register and was not removed by uninstall.

    As before, Rescue Disk ran and installed the new partition (DBR_BOOT) on WD Passport.

    However, backup system immediately stopped with disconnected, missing target location or full. Tried several times...

    In any case, sounds like you have solved your problem, so you like OP should this brand this post/thread as answered. I will continue to post on my other thread.

  • Reference Dell backup and restore (Premium Edition) 1.7.5.63

    Since upgrading my software Dell backup and restore to version 1.7.5.63, I now have problems to make it past the "Dell backup and recovery Please Wait" screen.

    I'm not leaving this option to run for more than 8 hours, but found that this process is not always successful. The only way I could find to block this process to run is to click on the? at the top right of the screen, then select "activity log". At this time, I clicked on the home button to take back me to the Dell Backup and Recovery Premium Edition home page and close the application. However, when I tried to re - open the application again, it brings back me to the screen "Dell backup and recovery Please Wait".

    To solve this problem, I tried to restore from a previous backup I made of the Dell Backup and Recovery application but it failed miserably and corrupted my hard drive and operating system (Windows 8.1). So the only way I could get back to who had to go back to my backup bootable disks that I created when I arrived to my laptop Dell Latitude E6530.

    Then I had re-installed all the 100 + updates of Windows for upgrade to Windows Pro 8.1 by the Windows store. From there, I upgraded my software "Dell backup and restore (Premium Edition)" at 1.7.5.63 and had the same problem again.

    In any case to have a fix for this or tell me how I can raise an incident with Dell, because this is so ignorant and frustrating.

    If I uninstall my Dell Backup and recovery software (Premium Edition) and reinstall the version found in http://www.dellbackupandrecovery.com/en-us/Index.html , but the last time I did, it installed the basic edition and not the Premium edition.

    All right enough the last time I had problems with my Dell backup and recovery (Premium Edition) software, it seems to settle on the other updated after a few months, but I don't don't want really to go back to an earlier backup with an older version of the recovery (Premium Edition) software and backup Dell.

    Any help or advice, you would be extremely grateful.

    I'm shocked that Dell is detrimental to Windows backup in Windows 7 Professional.  Your comments here persuade me not to pay for the premium edition.  Various people on other internet research said Dell had a great program backup, 6 months ago, but weakened while it is able to sell a version Premium, also hobble the program backup Windows.  You might try a free backup software like Comodo as I suspect that you can not use the Windows backup which makes a backup with files image.  It was a very simple approach that Dell seems to have stuck in their new versions of Windows 7 Professional.  I restarted my computer because of this kind of game.  Since I bought it at Costco, I have 90 days to return it.  I also started watching a series of online backups.  Carbonite seems terribly clutter my computer, and while highly recommended, it is slow, slow, slow.  I am CrashPlan that seems to work much much much faster.  Both of these are paid services.  CrashPlan has a lot of versatility to accommodate beginners to evolve into something much more powerful.  They have free versions for recording to hard drives and other computers.  The online version has Unlimited storage, much versatility, without the limits other plans have, and it's only 4-6 dollars per month, depending on the current sales and payment terms.

  • Reference Dell M620 and M820 ESXi 5.1 installation

    I'm relatively new to VMware on Dell hardware. The closest thing that I believe to a custom image is 'VMware ESXi 5.1 update 1 Image Recovery"(http://www.dell.com/support/drivers/us/en/19/driverdetails?driverid=RD5JN). I assumed it to be ESXi 5.1 update 1 with favorite Dell specifc driver packages. I had planned to use this new installs feeling that it would include the latest drivers for my Dell M620 and M820s and would be preferable to base VMware image.

    1. It is the support for the installation of these blades?
    2. The description says « Ce ISO image should only be used to restore/reinstall VMware ESXi on image for SD Card/USB Key on the supported Dell platforms. »
      • I am confused by the specification 'only' restore/reinstall and not install.
      • Also confused by the mention of the only card SD and USB to the apparent exclusion of standard hard drives.

    I installed with it as a test and it looks good, but I'm uncomfortable with the description. I would be grateful for any additional information or insight to those who support ESXi in Dell stores.

    Hi vmproteau,

    Here are my answers to your question based on my experience. I have no experience with the M620 or M820 I manages around 240 M610, 60 R710, the R720 10, so I am familiar with Dells ESXi 5.1 servers update 1.

    (1) Yes, I would recommend using the ISO provided Dell printer if you are not familiar with creating your own package with the necessary drivers and firmware.

    (2) this ISO standard will include all drivers for supported Dell servers and some customizations of Dell and can be used for new installations regardless of the storage (SD, USB or HD Local) option. I would like to look out for is mainly to make sure that you update the firmware on all of your blades with the most recent available by Dell that ESXi is very picky with the pilot and also incompatible firmware Dell CMC with thanks to a few mistakes from time to time.

    Kind regards

  • Reference Dell 2720 and 5.1 audio connections

    It seems that 5.1 audio can be connected via the HDMI port. I have a 5.1 system that can take the (optical) input SPDIF or 3 RCA connectors. Is there a form any card I can buy to connect the speakers? I am in Ireland and the only ones I can find are on OUR part or UK sellers provided here. I was wondering if there is a more standard option to connect HDMI SPDIF or RCS. Thank you.

    Well I found an answer. I bought a Cablesson HDelity HDMI Audio Extractor (CRA) who takes an HDMI output and it divides. So I plugged the HDMI from PC output to the input of the audio extractor. And then took the optical output toslink SPDIF audio and trendy extractor in my former speaker system and it works a treat. So I didn't need new speakers, just the junction box.

    It has also a SPDIF non-optiques a normal and a stereo output. All in all a little gadget very convenient, although there are some reviews on Amazon, saying it stopped working after a year or two. Others seemed perfectly happy with it. Does the job for me at the moment in any case.

  • Reference Dell backup and restore ends in error

    I just bought and set up a 3847 Inspiron with Windows 8.1 and I tried to create the backup of the plant and the DVD of restoration but the regime ended with a mistake twice.    It seems to happen at the end (ie. left 2 seconds) and then gives me an error indication.  It seems that he should try to check the DVD but it never does at this stage.  Does anyone know what gives?  The whole DVD is bad?

    In the case of only 1 system and no upgrade to the Premium edition, they are equivalent. The hot spare requires an external hard drive and backup of the plant requires a USB flash drive. I have not tried an SD card for a backup of the plant just a bootable USB for the backup of the plant.

    The hot spare is even as backup from the factory to the exception, you can use 1 external drive to factory settings for up to 10 systems Dell... If you use the Premium edition, you can get more advanced features like a custom backup and can set it to backup continuous data.
