I suggest you to refer to the following Microsoft article on Fix sound problems and check if it helps. Kindly let us know if you need any further assistance with Windows. We are glad to assist you. Was this reply helpful?

Yes No. Sorry this didn't help. Thanks for your feedback. Choose where you want to search below Search Search the Community. Having the highest level indicates that at some point in the past the user has set this endpoint as the default while the other endpoints, with a lower level value, were active.

Finally, if all endpoints contain a level value, and the endpoints with the highest level values are all tied, the endpoint rank is then used to break the tie. This indicates that these endpoints were active at the time of a default selection, but were not themselves selected.

We have no indication of user preference between these endpoints, so the automated ranking system is used. It is worth noting that with this new algorithm, a "new" endpoint is given increased weighting for becoming the default. This means that driver behavior that causes an audio endpoint to appear new to a system has the potential to trigger a default change.

Examples of driver behaviors and events which result in a loss of user settings on audio endpoints and will make an audio endpoint appear "new" to the system, potentially triggering a change in the default device, are:. The Windows 10 default audio endpoint heuristic for automatic endpoint selection is the same as the Windows 7 heuristic, with some minor modifications to the factor weightings to give a better user experience.

The default selection heuristic starts by collecting information about the audio endpoint; the factors. Each factor is then weighted and the resulting weighted values for all the factors are summed.

The resulting sum is called the endpoint rank. A rank value is calculated for each role for each endpoint console and communications. The Windows 10 audio subsystem considers the following endpoint characteristics, or factors , to select the default audio endpoint:. Windows 10 defines a set of enum values for every supported endpoint factor and stores them in the registry. Detailed descriptions of these factors and their corresponding enumerant value sets follow.

An endpoint with this capability implies that audio drivers can notify the audio subsystem when the audio peripheral device that is connected to an endpoint is plugged in or unplugged. Audio endpoints that support jack detection capability are called dynamic endpoints, and those that do not provide this support are called static endpoints. The Windows 10 default audio device heuristic treats all USB audio endpoints and Bluetooth audio endpoints as jack detection capable.

To determine an endpoint's form factor, the audio subsystem uses built-in fixed logic to map the Kernel Streaming KS pin's category KSNodeType , which is exposed by the audio driver, to a specific form factor. For more information, see EndpointFormFactor. The audio driver selects the KSNodeType for a KS pin on an endpoint because the driver has detailed knowledge about the audio device that might be connected to an audio jack. Therefore, KsNodeType reveals more specific knowledge on the endpoint than its form factor does.

This factor represents the bus type from which the audio device that exposed the audio endpoints was enumerated. The audio subsystem favors endpoints on a certain bus type over other bus types when all other endpoint characteristics are identical. For example, the system gives Bluetooth headphones priority over on-board HD Audio headphones to provide a better communications experience for the user; that is, when an end-user introduces a Bluetooth headphone device to this PC, the system makes it the default device.

General location indicates the physical gross location of the jack or device to which the audio endpoint is connected. Geometric location indicates the geometric location of the jack or device to which the audio endpoint is connected. The subtype specific property allows for future extensions of a heuristic value that is dependent upon the pin category property of the endpoint. Currently the only subtype specific property is related to microphone array geometry.

The Windows 10 default audio endpoint heuristic weights each endpoint factor. The higher a factor's priority is, the greater its weight. In addition, the Windows 10 heuristic assigns a rank value nRankXxx in this topic to each enum value within a factor category.

This rank value establishes the relative importance among all enum values under the same factor. Registry storage makes it easier for OEMs to customize the default audio endpoint's selection process. The set of parameters for the heuristic's rank calculation depends on the endpoint's characteristics.

The following table shows an example set of parameters. The audio subsystem calculates the weighted rank value for all active endpoints and selects the endpoint that has the highest rank as the default audio endpoint. The Windows 10 default audio endpoint selection heuristic mechanism also supports an exception feature. This feature allows the system or an OEM to cause the audio subsystem to designate an endpoint that matches a specific set of characteristics with very high or very low weighted rank values.

Such designations make the system's heuristic more flexible when it deals with unexpected scenarios. The heuristics for the console device role and the communication device role are separate, but the mechanism is precisely the same, with different order for the factors based on roles. Windows 10 ships with settings that are based on the heuristic details in this topic. The default console audio endpoint and default communications audio endpoint have different settings.

This section describes the settings for both types of endpoints. This section describes the default heuristic settings for each factor for a console audio endpoint. The factors are listed in priority order; that is, Windows 10 gives highest priority to the first factor in the following list when the audio subsystem determines the default console endpoint.

NOTE: These values may change in the future, the registry keys are the definitive source for information on the current values. Automatic updates could save you hours of time.

The Driver Update Utility automatically finds, downloads and installs the right driver for your hardware and operating system. It will Update all of your drivers in just a few clicks, and even backup your drivers before making any changes. Once you download and run the utility, it will scan for out-of-date or missing drivers:. When the scan is complete, the driver update utility will display a results page showing which drivers are missing or out-of-date:.

Many computer problems are caused by missing or outdated device drivers, especially in Windows If your desktop or laptop is running slow, or keeps crashing or hanging, there is a good chance that updating your drivers will fix the problem.
