Among the many faults with the equipment and in particular with the sound in Windows is possible to meet a red cross on the sound icon in the notification area and says “audio Output device not installed” or “speaker or earphone is not connected” thus to fix this error is often necessary to work hard.
In this article, I’ll tell you in detail about the underlying causes of errors “audio output device not installed” and “no speakers or headphones plugged in” in Windows and how to eliminate them and restore the sound or any other equipment.
First check again that they are just wired (as it happens that someone or something accidentally pulls the cord and you have not noticed).
Next take into account the subsequent factors if the first time you connect speakers or headphones to the front panel of the computer try to connect to the output of the audio card on the back panel unplugging it from the front the problem may be that the connectors on the front panel is not connected to the motherboard and it happens often just collectors considered it not necessarily.
Make sure that the equipment(speakers or headphones) connected to the correct connector (usually this connector is green).
If all the connectors are the same color then output to speakers or headphones most often circled color.
If you think it is — try to connect any other speakers or headphones for example from a smartphone.
Probably this topic would start a topic about “audio Output device not installed”.
Press the key combination Win+R type devmgmt.msc in the Run window and click Enter key — this will cause device Manager in Windows 10, 8 and Windows 7.
Usually when Troubleshooting with sound the user checks the item “Sound video and game controllers” and look out for if there is its audio card — Realtek High Definition Audio, Realtek HD Audio or similar.
Anyway the problem is the “audio Output device not installed” the most important thing is the “audio Inputs and audio outputs”.
Make sure is there such a thing available and whether there is a headphone output and not muted if they (for detached equipment visible down arrow).
In the presence of the disconnected device — click right click on that device and select “Enable device”.
If the list of device Manager are there any unknown devices or devices with errors (yellow icon) — try to delete them (right click — delete) and after that in the menu of device Manager click “Action — scan for hardware changes”.
The next thing to do is to make sure that there are appropriate drivers for your audio card and they work.
An inexperienced user must check such moments: if in device Manager under “Sound video and game controllers” you notice items something like NVIDIA High Definition, Audio AMD, HD Audio, audio for Intel displays — apparently Windows doesn’t see audio card and it is possible that it was not involved in the BIOS (on some motherboards and laptops this is the case) or just the driver.
And what you find is a device to output dynamics via HDMI or Display Port which are outputs of your graphics card.
If you click the right button of the mouse on the audio card in device Manager then selected “Update driver” and later the automatic search for updated driver software told you that “the Most appropriate drivers for this device are already installed” — this does not mean that you have actually installed the correct driver: easily in Windows update there was no other relevant.
Drivers for audio Realtek and others can be successfully installed from a third party driver packages (driver packs) but not always the correct work — you need to install the drivers from the manufacturer of specific hardware (such as Asus, Samsung and etc.).
Overall if the audio card visible in device Manager the correct steps for installing the right driver will have the following: Go to the official website of your motherboard or your brand of laptop (for example type into the search engine the name Asus) and go to the “tech Support”.
Choose in the list your model or make using the form and download the suggested drivers for your hardware (sound card, graphics card, wifi adapter, and etc.).
Typically sound cards drivers are marked as Audio.
If suppose you have Windows 10 but the official the website only drivers for previous versions of Windows 7 or 8 — confidently upload them.
Open device Manager and uninstall under “Sound video and game controllers” your audio card (right click — Remove — tick “Remove application drivers for this device” if such appears).
After the installation check whether the device worked.
Another sometimes valid option (suitable for those cases where “it worked yesterday”) — look in the properties of the sound card to the tab “Driver” and if there is available the button “Roll back driver” click on it (from time to time Windows may automatically update the drivers on the wrong).
Look in the BIOS (UEFI) in tabs Advanced/Peripherals/Onboard Devices something to do with Onboard Audio and make sure that this option is active (Enabled).
If you have connected a monitor (or TV) via HDMI or Display Port or any adapter then configure the audio devices can help.
Just right click the sound icon in the Windows notification area (lower right corner) and go to “playback Devices”.
In the list of audio devices right click your mouse and select Show disabled devices and Show disconnected devices.
Make sure that the sound output device by default use headphones or speakers (not HDMI output etc.).
If you need to change the equipment’s default — click on it and select “Use default” (turn right to turn on “Use hardware default communication”).
In conclusion, a few other sometimes working how to fix the problem with sound and with other similar equipment if the preceding methods have failed.
If in device Manager in the “audio Outputs” can be seen weekends audio devices, try to remove them and following this in the menu Actions — scan for hardware changes.
If you have a Realtek audio card then look in the fad of the “Dynamics” of the program Realtek HD.
Enable the correct configuration and in the “advanced device configuration” checkmark “to Disable detection of nests front panel” (even if problems are detected when connecting to rear panel).
If you have a fancy audio card with its own software to control check once again whether in this or IN any configuration that can interfere with sound card.
If the problem came after a update to Windows 10 and the above methods driver failed try to restore the integrity of system files using the command dism.exe /Online /Cleanup image /RestoreHealth.
In a pinch, you can try the option of system restore points if before the sound worked properly.
Note: in this article I will not talk about the way to automatically troubleshoot Windows with sound because you’ve tried it the very first (if not try it can affect).
That’s about it.
I hope you will succeed.
