Devices with High Definition Audio support. A device with High Definition Audio is not connected

Sound devices with support for High Definition Audio are new, but they have become quite widespread in the computer environment. But, despite the most advanced technologies used in them for audio playback, it is sometimes possible to encounter errors or software failures when there is no sound in the system, and she herself with enviable persistence issues a message stating that the playback device is not connected. How to deal with this, will be further discussed.

Devices with High Definition Audio support: what is it?

In general, such integrated devices are usually referred to as integrated Realtek sound cards (in general), although NVIDIA or MSI products are less common. As a rule, in the system they are recognized as sound cards or speakers. A device with support for High Definition Audio of this type uses advanced technologies to increase the transmission frequency, reproduce the newest audio formats, more accurately recognize voice input, connect "hardware" as Plug & Play, etc.

But only this basic characteristics are not limited. The fact is that any audio device supporting High Definition Audio is initially oriented to full compatibility with Direct Sound 3D, and installing the appropriate driver and additional software makes it possible to use a 10-band equalizer, about 26 sound environments in modern games, to connect electronic music Tools through the MIDI interface and much more.

However, not only sound cards are included in this list. You can also include a microphone here. A device with support for High Definition Audio of this type is just focused on a more subtle recognition of speech or speech commands, not to mention that even with the built-in microphone of the laptop, in the absence of outside noise and interference, you can make a fairly good voice recording. Of course, this sound can not be called professional, but in the absence of a studio microphone, even such a recorded sound sounds, in general, not bad, not bad.

A device with High Definition Audio support is not connected: symptoms of malfunction and causes

But why then does the system sometimes report that this component is not connected? The most common situation: devices with support for High Definition Audio in the system are installed, the drivers seem to be in order, and the sound in the speakers on the output is missing, although with the headphones it is.

When you call the settings panel, the speakers are marked with a red circle, and a little lower is the notification that they are not connected, although all the inputs and outputs work correctly. But a complete misunderstanding of the situation is caused by the fact that such a malfunction can occur even on laptops with built-in speakers, for which separate outputs and cords are not needed.

The main directions in the methodology for troubleshooting

You can restore the device with support for High Definition Audio in several ways, if only it did not fail.

Among the main methods are the following:

• Reinstalling or updating drivers;
• Removal of the HDA system controller;
• Setting different from the initial parameters of sound output.

Reinstalling Drivers

The first step is to try to reinstall the drivers, using for this not the "Device Manager" (although in the simplest case, too, you can), but, for example, the original disk or downloaded from the Internet driver, and from the official website of the manufacturer.

Note that the drivers can be of two versions: for Windows versions 2000, 2003, XP and Windows Vista and higher. Choose the one that matches your system.

However, the easiest way to apply programs like Driver Booster, which directly from the manufacturer's resource download the most suitable updated driver and without your participation integrate it into the system. It does not give a one hundred percent guarantee that the device will be operational, but this option can not be excluded.

Removing the System Controller

Judging by the feedback from users who have encountered this problem, another solution may be the complete removal and automatic installation of the HDA system controller (note that there may be several, so you need to delete everything).

You can perform this operation in the same "Device Manager" by selecting the delete line from the system in the PCM menu on the controller. As noted, when you restart Windows itself will determine the controller and install the necessary software for it. In general, it's also worth a try, since Windows-system cards and Realtek drivers (or other common devices), as a rule, recognize without problems, installing drivers even from their own database.

Changing sound settings

Finally, another technique is to change the settings of the working device. True, this method is more applicable to stationary computer systems, and not to laptops, in which the outputs to the built-in speakers are not provided (although in some situations the change of the program settings of this nature allows to eliminate the arising problems).

In this situation, you need to call "Realtek Manager" (you can use the PCM menu on the system tray icon with the choice of the playback device line), then check the option for disabling the front panel socket detection on the speaker configuration settings tab. As practice shows, in many cases such a decision works. After this, however, it will be desirable in the settings of the Realtek panel to set the selected speakers as the default playback device.

Conclusion

In general, these are the most common situations and solutions that allow to eliminate a program failure of this type. In this case, it is meant that the device itself is fully operational and has no damage. In addition, it is also advisable to check whether there is any additional player or panel in the system that can affect the sound settings. This option is also not excluded, because some sound program modules can intercept the management of the sound card, so the volume in the system seems to be turned on by 100%, but in fact in the other program that took control of the playback, completely off. Finally, it is worth checking if several drivers or devices are installed, because they can cause conflicts between each other. In general, except for physical breakdowns, these are all the main methods for correcting the current situation.
