• My helmet is bright red, and the speakers does not work, when I try to adjust the volume when there is no headset/speakers in, there is a sign of the cross as the symbol of the volume where the places are supposed to be, macbook pro retina display

  My helmet is for some time, as the eye of the terminator, glowing and speakers have not worked since. I need to plug headphones or external speakers. Whenever I try to adjust the volume when it shows just a cross symbol under the sign of the volume, where small squares usually are (see below)

  

  Is there a way to fix this? Some other similar forums tell me to try to manually move a switch in the audio jack, but I can't seem to find such a change and the thing that seems most like a light switch, does not move.

  Can someone please help?

  Thank you

• My speakers does not work when I talk on the phone but when I have my headphones or have the phone up to my ear people hear me perfectly fine, please help.

  My iphone does not work on audio speaker and everything is perfectly fine, but when I'm on the phone and put my phone on speaker, no one can hear me not at all, but when I have the phone to my ear, or have headphones in people can hear me very well. I don't think it's a software problem, that my phone is updated with ios 9.3.5. Can someone help me please on this issue.

  Force restart the phone now sleep and home for 10 seconds, button until the Apple logo comes back again. You won't lose data.

  Have you tried plugging the headphones into an output a few times?

  Does say "headphones" when you toggle the volume and no headphones attached?

• Wireless mouse does not work when it is docked.

  I have a new laptop Latitude E7440, with a mouse Dell Wireless and E-series docking station.  When it is docked, the wireless mouse is disabled.  Receiver must USB mouse be connected to the docking station to make it work? It would be quite embarrassing.

  Thank you

  Hi dwells1957,

  Thanks for the post! Looks like you might have the USB receiver connected to the USB ports on the back of the system? While anchored feature transfers E7440 of ports at the back of the unit to the Wharf (by disabling these ports).

  Rear ports Latitude E7440 & E7240 system are disabled when it is docked on an E-port I / II or E-port Plus I / II

  If you connect the USB receiver on the dock or on the USB port on the side of the system, it should work correctly when it is connected to the docking station.

  Kind regards

• Satellite P100-240: speakers do not work

  I have a Satellite P100-240 with built-in speakers. Recently the speakers worked intermittently with no control over the volume (the volume was extremely low). Now the speakers do not work at all, either from a cd or a sound system.

  Can you help me?

  Hello

  You must know that in such cases is really not possible to give a precise explanation. If the audio device is installed correctly and in Device Manager is not listed as problematic there must be a problem with the settings.

  First try to check all the sound settings and make sure that the mute box is not selected. Also check dial volume control. If everything is set to max level and no MUTE is ENABLED, please check the features that you use headphones.

  Please post the results.

• L300 satellite speakers do not work - no audio device not detected

  I just bought a L300 and the speakers do not work.
  The computer says there is no audio device detected and when I checked it is said more far there are no drivers installed for the speakers, and I can't find a way to install them. Can anyone help?

  Can I ask you if you use the OS preinstalled Toshiba?
  The message; No audio device detected means that it sound card doesn't work.
  Why? Well, maybe the audio driver has not been installed properly?

  Please check this!

  PS: Is there any yellow exclamation point in Device Manager?

  Hello @hifive11,

  I read your post on how your laptop speakers do not work, but the headphones work fine, and I'd be happy to help you in this case!

  The first step that I recommend is to follow this document on the no sound on speakers (Windows 7). This should help to restore the sound from your speakers.

  You can also activate the speakers on your computer as default playback device. This is possible by following the steps below:

  1. click on the Start button

  2. click on Control Panel

  3. click hardware and sound (the icons of sort by 'category' Control Panel) and then click on its

  4. under reading, you should see one or two speaker icons. One of them should have a green check mark next to it (which will be the helmet of your laptop device). If the second speaker icon is not visible, right-click in the list of devices and select Show disabled devices

  5. a second disabled icon "speakers" should appear. Right click on this icon, then click Activate

  6. test your speakers

  If the problem persists, I recommend to you your laptop a previous restore point before the speakers stopped working. This can be done by following the steps described in this document on using Microsoft System Restore (Windows 7).

  Please re-post with the results of your troubleshooting, and I look forward to your response!

  Hello

  Try the following.

  Open windows control panel, open Windows Update, select "View update history" in the left pane and then select "Installed updates" link in the next window.

  Locate the KB2962407 update, right click and choose uninstall.  Once completed, restart the computer, open windows control panel, open Windows Update and select "Check for updates".  You will see the update that you have uninstalled just offered once again - right click and select "Hide update".

  After that you may or may not need to remove and reload the sound driver - if you do, how to use Recovery Manager to reinstall the drivers and software is detailed in the document in question on the link below.

  Did you of recent changes to the computer?

  Method 1:

  Check if your headphones are configured to be used as a Communication device by default instead of the default device, or if the two devices are configured by default. If so, that the fault of headphones, so that Windows will only use when they are connected.

  (c) make sure that you have "Default uncontrolled communication device".
