E7440: Audio Jack does not detect all connect more

Hi all

I am reported a strange problem. I use E7440 with Windows 7 64-bit with Realtek HD Audio driver (as shown below). My computer also has 'AUDIO DELL' management utility.

Previously, external headphones and portable speakers were working well and whenever I used to insert the pin code of my headphones into the audio jack, a small pop-up used (from the utility DELL AUDIO) used to make appear to select the type of device, I just inserted.

What happened was, as usual, I inserted the headphones and the popup appeared. I somehow click outside (or closed the popup window) without selecting the device type. Since then, whenever I re - insert the PIN in the audio jack, it behaves as if nothing had happened.

I tried to fix it by the following methods, but always the same problem.
-Inside the DELL AUDIO utility, there is an activation or deactivation pop up under the menu option "Advanced > Jack Information." I tried to switch it, thinking that he can reset the pop-up.
-Inside the DELL AUDIO utility, there is an option to restore the default settings in the menu "Advanced > Restore Defaults. But it also did not help.
-I uninstalled my audio driver from Device Manager. During the restart of the computer after the uninstall, it automatically installed the audio driver again. Once I did, my speakers have also exploded. In other words, no sound of two internal speakers laptop no audio jack. I had to restore my computer to one of the restore points to undo this uninstalling the driver and reinstalling.
-I also tried update utility DELL AUDIO via the utility "update DELL client system. But it seems that this utility has some problems too, as ever, he proceeded as planned. I had to do a system restore to restore my computer on track.

Current situation is the internal laptop talk work very well and any plugin for the audio input jack is not pop - up (to select the type of audio device) while the DELL AUDIO has the option to display the pop-up windows when a new device is inserted.

I have not checked in any other operating system yet. But I'm sure it's the problem of the DELL AUDIO utility.

Any guidance will be much appreciated by me and the people around me, who have to listen to my stuff because of this problem of the audio input jack.

Best regards

Hello. We have a lot of posts this year on taking undetected on laptops Dell with Realtek audio. I suggest that you try to install the native Windows audio driver. The method is similar to what you were doing when you uninstalled the realtek driver.

Open Device Manager (type devmgmt.msc in the search box), and then expand "audio, video and game controllers".

Right-click on "Realtek High Definition Audio", and then select uninstall. This time, put a checkmark in the delete files optionand then on ok. When you restart, Windows will install its own native driver or another driver Realtek if there were other versions on the hard drive. Then go back to Device Manager and look for a Realtek driver. Keep the uninstall & reboot (removing the files each time) until Realtek no longer appears under controllers of noise. Finally, you will see "High definition Audio Device" (native Windows driver) instead of "Realtek High Definition Audio"

Must work with this driver. If it's not, and if you are still under warranty, report the problem to technical support.

If the Jack is working, then next download and install a new copy of the driver Realtek. The Audio from Dell Manager is really a truncated version of the Realtek Audio Manager. I don't know, but you might get a new copy of the Audio Dell Manager with the new copy of the Realtek driver. The actual address of Realtek Audio Manager has better controls for the headphone jack, but apparently we can't get it in a Dell laptop.

If it still doesn't work then try a driver directly from Realtek website. (Return to the native Windows driver each time before trying any different Realtek driver.) You can try the Dell offer and the Realtek drivers.

    Hello, my new Dell XPS 15 audio Jack does not work. I just got this thing out of the box.

    I tried several headphones as well, the helmet is not the issue.

    I've isolated to this: when I plug in the headset, nothing happens. If I ask about 15-20 lbs of pressure, forcing the connector of headphones into the socket as hard as possible, the cell begins to recognize and the helmet works. As soon as I let go of the connector, the laptop will behave as if the device was disconnected.

    Hello

     
    If you are comfortable to open the CPU Tower and disconnect the wiring for the front cable which goes from this Jack to the Audio card, you can go ahead and perform the same. You can also contact the manufacturer of the computer for support.
     
    I hope this helps!

  • Windows XP does not detect any internet at all despite the computer with the modem to work.

    I recently installed Windows XP Professional on my new iMac via bootcamp.  While Windows itself works fine, it won't connect to internet at all.  Despite being connected to a modem ADSL via a Ethernet cable, and also have wireless internet, Windows does not detect any signal.  On the internet in the Control Panel, all connections page that appears is "1394 connection" under the heading "LAN or Internet high speed."  I tried several times to put in place a new internet connection through the Setup Wizard and everytime, no internet is detected.

    I know that the modem works because all the other computers in my house are fine online, including on the side of Mac of the iMac.  If anyone has an idea as to how I should resolve this problem, your help would be greatly appreciated!

    Thank you

    Daniel

    Moreover, these are things I've already tried:

    I've tried to manually and automatically set up an internet connection
    I spoke with my ISP, the modem works fine
    I have re-partitioned the hard drive and reinstalled XP

    The "1394 connection" is the IEEE 1394 (FireWire) from your computer.  There should be cable system and under the heading wireless connections "LAN or Internet high speed."   There is no need to run the Network Setup Wizard or set up a new connection.

    Open the Device Manager (Start > run > devmgmt.msc ) and go to the network adapters section.  You may need to install the drivers for them.

  • Connection problem diagnosis - "the remote device or resource does not accept the connection detected.

    My computer is a Windows Vista Home Premium 32-bit. The problem occurred about 2 months ago, while he was still in Vista, but please note that I've upgraded to Windows 7 last night and the problem is always the same.

    My Internet Explorer, updates to the computer, iTunes and everything, EXCEPT my AOL, does not work. My connection says 'excellent '. (Hang everything on my laptop to my wireless are works fine, that my office is having this problem)
    When I click on Internet Explorer, it says "Internet Explorer cannot display the webpage", and when I click on "analyze the connection problem" said "problems discovered - the remote device or resource does not accept the connection detected.
    I talked to my internet provider Comcast all morning this problem: she said that his side internet connections work properly. She walked through me steps including reconnected the router cords, control the way in which the Internet is put in place and other things, but everything was how it was supposed to be. She suggested that maybe AOL could be the problem and to remove it because I used it, so I did, but nothing has changed. So then she told me to contact Windows... (not sure how to call technical Windows supports without having to pay $59?, but found this forum)
    Is anyone familiar with this problem and could you please help or at least point me in the right direction?
    In addition, please let me know if you need any other information on the problem.

  • HP 8500 replaced, software does not detect printer even though I can't ping / connect to the web interface

    Windows 7 Pro 64

    Reference Dell

    Printer connected via ethernet

    software worked well until the printer has been replaced by HP under warranty

    in the new device, the screen of the wizard to set the time/language etc.

    Software HP does not detect the device and so I can not use all the features.

    I can connect to the printer via IP and also tried to put the TCP/IP port with printer static IP. Can I print using this, but the software "suite" does not detect the printer.

    Removed all software, cleaned the registry, removed the IP port, re-installed the software, does still not detect printer.

    Installed HP printer diags and it passes all the tests, but the suite software HP will always be NOT detect printer.

    Tried without firewall, tried with, still can ping printer, connect to the web interface, the static value, always the software does not detect the printer... so whats left to please other than an another replacement warranty which is used to solve the problem, as it is definitely bad coding in the suite.

    I also tried downloading drivers/full later on the HP site.

    Note that all windows updates are met, reconstruction is out of the question that it is a machine of the company and would almost take me 3-4 days to replace all the software on it (Sage, DW, COFFEE, HMRC).

  • My new airport does not detect my existing WiFi network, I can connect only via the LAN.

    Bought a new airport 1 TB TimeCapsule and I wanted to add to my existing via a WLAN network. It does not detect it and I can connect only via the LAN. What I am doing wrong?

    Unfortunately, unable to connect to a 3rd time Capsule part wireless using a Wi - Fi.

    You need to connect to the time Capsule to your existing modem/router using a wired Ethernet cable connection, permanent... like the Time Capsule Setup Guide illustrates.

    If you really don't want the time Capsule to connect using the wireless... she can do... If it gets a signal to another Apple wireless router. So if you were ready to add another Apple... as an AirPort Extreme router... and connect it to your existing Ethernet cable router/modem and configure AirPort Extreme to broadcast a wireless signal... .then.. .the Time Capsule would be able to connect in this way, assuming that he is where he can receive a good quality of AirPort Extreme wireless signal.
