Latitude E7440 - sound does not come with a helmet

Hello world

I have a laptop Dell Latitude E7440 8.1 Windows running. I had problems with no sound coming with headphones plugged in the headphone jack (its only comes through the built-in Laptop speakers). I tried several fixes including:

-Definition of headset as default playback device (my laptop groups speakers and headphones together, is not possible to choose one over the other).

-Remove the battery, now hold the power for 30 seconds, turn it back on

-Update Realtek Audio driver

-Uninstall the Realtek Audio driver (and deletion of files), and then restart the computer for the native audio driver is used.

I had the most success with the help of the native audio driver (after deleting and uninstalling Realtek). However, when I do this, I have from both headphones and speakers of the laptop. This will work for a day or two, then I'll start to have no sound from the headset again (despite running the native audio driver).

I don't know if it's a hardware or a software problem. I don't think it's a hardware problem, since I am able to get the headset to some working hours. Are there new ideas or advice? I'm debating getting a USB adapter for my helmet, but I don't know which would solve the problem if it's a software problem.

Thanks for the help in advance!

I'm debating getting a USB adapter for my helmet, but I don't know which would solve the problem if it's a software problem.

The usb sockets are very expensive and me would be worth the risk that it might not work. You could test the hardware failure (or repair the software if it's a software problem) by resetting the laptop back to the factory setting original, but for many people it is worth some money to try and avoid would do that.

Usually when the headphones are not detected by the driver from Realtek but are when you use the native driver, the solution is to completely remove the software Realtek, the way you did and then install an earlier version of the Realtek driver. However, it is difficult to understand the symptoms of your laptop. Normally if there is the same symptom with pilot of the provider and the native driver, which is strongly evocative of hardware failure because both pilots are not likely to have the same bug at the same time. In your case, but I wouldn't bet on it anyway.

    Hello

    I have no idea what could cause this but I recommend to update the audio driver.
    Download the latest driver from the Toshiba driver page.
    Then go to Device Manager and uninstall the old audio drivers.
    Then, go to downloaded new driver sound and install it.
    Restart the device and test the sound plays an MP3 for example

  • I already bought the movie HD, 'V for Vendetta', before it came with "iTunes Extras" but my purchased copy does not come with the Extras. Is there a way to fix this without having to buy the movie again?

    I already bought the movie HD, 'V for Vendetta', before it came with "iTunes Extras" but my purchased copy does not come with the Extras. Is there a way to fix this without having to buy the movie again?

    I was told that movies in the iTunes Store can be changed to include "iTunes Extras" if originally it did not come with extras. But there is a catch you get just the extras if you buy just the issue for the first time. If you have already purchased it, your version may not have the extras. This means that if you want the extras, buy the movie again.

    If you now get the Extras will depend on what the movie studio did for example if they have updated the version you have purchased, or replaced by a new version (which will be treated as a separate purchase): buy and play movies with iTunes Extras - Apple Support

    Hello

    My Hp Pavilion laptop 2244sa g6 does not come with the product key for windows8. Is this normal? I can't see it anywhere, should I worry?

    Some laptops, like my Envy 17-3002ea loan, have the certificate of authenticity Windows hidden in the compartment where the hard drive and the battery are.  First try.

    Other portable latest and which may include yours, have the Windows license key encrypted in the BIOS.  There is a thread on the Microsoft communities that verifies that. The thread is worth reading.

  • HDMI sound does not come through my HD TV

    My laptop model is a HP Pavilion g series

    The first time I connected my laptop to my HD TV was fine. But after the second time I see on the TV screen but my functioning collapsed, I meant I had the sound that passes through the laptop but it does not recognize the HDMI cable. I thought that it was problems with the cable, so I plugged my Latop wife to find out and it works fine. so I went and tried to update the software and it says everything is up-to-date, but now I can't make the sound come through the TV more. can someone help me please?

    Hello

    the g series has dozens of models, which is yours? HDMI to reactivate sound can help.

    • Right click on the speaker icon,
    • Select the playback device,
    • Click with the right button on its HDMI,
    • Activate it.

    I hope this helps.

  • Satellite C70D-A-11 t - sound does not work with HDMI

    Hello

    I buy a Satellite C70D-A-11 t and pass it on Windows 7 64 bit Home Premium edition.
    I have install all drivers, and I have no problems.

    When I want to connect it to my TV for the first time, I discovered that there is no sound on the TV.
    I try to go on the speaker (near windows clock), right-click, sound, first tab (I think it's 'Read' in English... I have a french Windows) and my device (TV) does not appear.

    I'll be back on the Web site of Support of Toshiba to download the latest driver "HDMI Audio driver" for my laptop, I connect the cable, and it appears in the sound properties. I select it as default device and the Øresund have just my TV.

    Great!

    But when I restart my laptop (with or without the HDMI cable), TV disappear from the list in the sound properties, the only solution to reinstall the Audio HDMI driver to retrieve the sound.
    If I start the installation of the driver with the 'Advanced' option, I have the list of drivers to install and I see all the drivers are already installed, but the HDMI Audio Driver will be modernized... I have install and it works until the next reboot.

    Could you explain to me why the version of the driver do not remain on the system, and how to do the work without reinstalling every day?

    Thanks a lot for your help.

  • Satellite P500-127: microphone or sound does not work with Skype

    Hello, team Toshiba,

    Recently bought a new laptop.
    However the microphone or the (pebble connexant high definition) sound driver does not work correctly when you use Skype. Also read about in various forums such as the Skype forum.
    People ran into similar problems such as:

    -------------------------------------------
    Usually, we can speak of a little more than 20 seconds, but the call will be at a random time between 1 and 15 minutes. The strange part is that sometimes the quality of the call is good, but more often my friend can't get along * half of what I say * while I don't usually have a problem to hear what was said. The video works so my friend can see talking me but can simply not really hear what I say.
    Before the fall of the call usually freezes for a few seconds and then Skype crashes sometimes. We tried to talk together without the video, but the problem remains.
    ---------------------------------------

    I also found a suggestion by the toshiba service, just to simply increase the volume under the Panel etc, but it does not work either...

    Can you please help me on this one?
    Cannot use Skype at all as she just to boring for everyone I talk... The quality is fair to poor.

    Thank you very much

    Hello

    I have the Skype m user too and to be honest, everything works fine!
    I can use my internal webcam as well!
    But I m using Win XP with Skype

    I assume you are using Win 7 and Skype

    To be honest, I doubt s number of Toshiba laptop
    If it would be a matter of (audio driver) laptop so you have seen the same problems recording and creating audio files... but I doubt that will happen...

    Therefore, it must be a software problem possibly a combination of Skype, Win 7 and driver Conexant
    Who knows

    But as I said above my Skype works well with Win XP!

  • Sound does not work with headphones

    I have to attend an online presentation. We have checked all the settings of the sound card, but all I can do with my helmet is talk, but I can't hear anything in my headset if someone speaks. I need to first unplug the headphones to hear anything in the boxes of two speakers. I bought a new headset, but that did not help. I was looking for some drivers etc but can't find anything. Anyone know what I need to do to talk and hear the other participants at the same time with my helmet?

    Thank you very much

    Hello Nicci

    You already end solution? I put t know which model of laptop, you have, but they all work on the same path. Please check the volume control if it has disabled mute box (control volume and waves).

    In device manager there is no problem with the sound card, it should work properly. Check please properties of sound and Audio devices in Control Panel. I'm sure that some settings is not set correctly.

  • iTunes 12 sound does not work with ac3 passthrough

    I have an Intel DX79/Xeon 2, CPU 0GHa with a NVidia GTX680 graphics card.

    I use an HDMI output directly to a Denon surround amplifier. Everything had been working well for a few years but recently I reinstalled Windows 8.1 and I found the passage of in surround AC3 stopped working with iTunes.  Movies of the source that I use have 5.1 channels and used to work.  Nothing the silence I fear when "Prefer AC3" is now selected.   The material has not changed - just a re-installation of Windows with the latest version of iTunes 8.1 and NVidia version 359.06.  The installation is completely vanilla flavored outside these two packages being installed.

    So, I added PowerDVD and tested with a couple of BluRay discs.

    PowerDVD works well with AC3 pass by - the problem seems to be limited to iTunes.  Stereo mode in iTunes works fine.  I tried the "Old video card" version iTunes without success and I tried without downgrading the video version card / audio driver for NVidia 344.75 (a version I know that used to work for about a year back) all to nothing does not).  I also tried version 12 iTunes and encountered exactly the same problem. I think that maybe iTunes and the driver NVidia do not play well together.  All the world is this problem?  I tried to contact Apple support, but it generates an error with a hexadecimal error code large enough and said "try again later...". ', Useful suggestions are welcome!

    Hey there,

    I just saw your post - I had the same problem and posted my fixed on a different thread, here: AC3 Passthrough works does not in 10 - bug and workaround windows
