Feature Summary
Here are the new audio features in Windows 10.
Low Latency Audio Improvements
Audio latency is the delay between that time that sound is created and when it is heard. Having low audio latency is very important for several key scenarios, such as the following.
The total latency of a device is the sum of the latencies of the following components:
In Windows 10 work was done to reduce the latency in the OS. Without any driver changes, applications in Windows 10 will experience 4.5-16ms lower latency. In addition, if the driver has been updated to take advantage of the new low latency DDIs that use small buffers to process audio data, then the latency will be reduced even more. If a driver supports 3ms audio buffers, then the roundtrip latency is ~10ms.
The audio stack supports multiple packet sizes and dynamic packet resizing, in order to optimize the tradeoff between latency and power based on the user’s scenario. In addition, streams will be prioritized, in order to ensure that high priority streams (e.g. phone calls) have dedicated resources.
In order for audio drivers to support low latency, Windows 10 provides the following 3 new features:
Signal Processing Modes and Audio CategoriesSignal Processing Modes
Drivers declare the supported audio signal processing modes for each device.
Audio categories (selected by applications) are mapped to audio modes (defined by drivers). Windows defines seven audio signal processing modes. OEMs and IHVs can determine which modes they want to implement. The modes are summarized in the table shown below.
Audio device drivers need to support at least the Raw or Default mode. Supporting additional modes is optional.
Dedicated modes for speech, movie, music and communications. Audio drivers will be able to define different type of audio formats and processing, based on the stream type.
Audio Categories
The following table shows the audio categories in Windows 10.
In order to inform the system about the usage of an audio stream, applications have the option to tag the stream with a specific audio stream category. In Windows 10 there are nine audio stream categories.
* New in Windows 10.
For more information see Audio Signal Processing Modes and Audio Processing Object Architecture.
Hardware Offloaded APO Effects
Windows 10 supports hardware offloaded APO effects. APOs can be loaded on top of the offload pin. This allows for the audio processing to be done in both software and hardware. In addition, the processing can change dynamically. Some or all of the processing can be moved from the software APO to the DSP when there are enough hardware resources and then moved back to the software APO when the load in the DSP increases.
For more information, see Implementing Hardware Offloaded APO Effects.
Cortana Voice Activation - Wake on Voice
Cortana, the personal assistant technology was first demonstarted at the Microsoft BUILD Developer Conference in 2013. Voice activation is a feature that enables users to invoke a speech recognition engine from various device power states by saying a specific phrase - 'Hey Cortana'. The 'Hey Cortana' Voice Activation (VA) feature allows users to quickly engage an experience (e.g., Cortana) outside of their active context (i.e., what is currently on screen) by using their voice. The feature is targeted for scenarios when the screen is off, idle or when it is fully active. If the hardware supports buffering, users can then chain the key phrase and command phrase together. This improves the end to end wake on voice experience for the user. For more information, see Voice Activation.
Windows Universal Drivers for Audio
Windows 10 supports one driver model that works for PC and 2:1’s and Windows 10 for phones and small screen tablets. This means that IHVs can develop their driver in one platform and that driver works in all devices (desktops, laptops, tablets, phones). The result is reduced development time and cost.
In order to develop Universal Audio Drivers, use the following tools:
Resource Management for Audio Drivers
One challenge with creating a good audio experience on a low cost mobile device, is that some devices have various concurrency constraints. For example, it is possible that the device can only play up to 6 audio streams concurrently and supports only 2 offload streams. When there is an active phone call on a mobile device, it is possible that the device supports only 2 audio streams. When the device is capturing audio, the device can only play up to 4 audio streams.
Windows 10 includes a mechanism to express concurrency constraints to insure that high-priority audio streams and cellular phone calls will be able to play. If the system does not have enough resources, then low priority streams are terminated. This mechanism is only available in phones and tablets not on desktops or laptops.
For more information, see Audio Hardware Resource Management.
PNP Rebalance for Audio Drivers
PNP rebalancing is used in certain PCI scenarios where memory resources need to be reallocated. In that case, some drivers are unloaded, and then reloaded at different memory locations, in order to create free contiguous memory space. Rebalance can be triggered in two main scenarios:
An audio driver is a tiny program that enables the operating system to communicate with your audio hardware on your computer. It is essential in keeping the sound card in good performance.
If the audio drivers is outdated, faulty or missing, you might experience no sound, sound cutting out, bugging or crackling issues. So you should always make sure to have the latest audio drivers on your computer.
How to update Microsoft audio driver
Both methods work in Windows 10, 8 and 7. And as the method list suggests, you don’t have to try both. Just decide if you want to do it manually or automatically and take your pick:
Method 1: Update my Microsoft audio drivermanually
A WORD OF WARNING: Downloading the wrong driver or installing it incorrectly will compromise our PC’s stability and even cause the whole system to crash. So please proceed at your own peril. If you’re not comfortable playing around with drivers, or worrying about any risks in the process, jump to Method 2.
As it turns out, Microsoft doesn’t provide drivers(except for those built-in generic ones that come in with Windows, which are always subpar). So in order to manually get the right audio update for our computer, you might have to meet at least one of the following requirements:
Alright then, let’s get started:
1) Go to your branded PC’s official website or your audio card’s manufacturer’s website (if you know exactly what brand and flavor of audio driver your computer is using).
2) Check out the Support section for driver downloads.
3) Find out and click the right download link for your variant of Windows operating system. Usually a few download options will be listed but you might want to click the first result for the latest driver version.
4) Check the downloaded file:
5) Double-click on the file to install.
6) Restart your computer for changes to take effect.
7) After the un-zip, see if there’s an executable(whose name ends in .exe)
If yes, double-click on the .exe file to install. Then restart your computer for changes to take effect.

If no, then check out this link for steps to install your audio driver manually.
Method 2: Update my Microsoft audio driver automatically (Recommended)
If you don’t have the time, patience or computer skills to update your audio drivers manually, you can, instead, do it automatically with Driver Easy.
Driver Easywill automatically recognize your system and find the correct drivers for it. You don’t need to know exactly what system your computer is running, you don’t need to risk downloading and installing the wrong driver, and you don’t need to worry about making a mistake when installing. Driver Easy takes care of it all.
You can update your drivers automatically with either theFREEor the Pro version of Driver Easy. But with the Pro version it takes just 2 clicks (and you get full support and a 30-day money back guarantee):
1) Downloadand install Driver Easy.
2) Run Driver Easy and click the Scan Nowbutton. Driver Easy will then scan your computer and detect any problem drivers.
3) Click Update All to automatically download and install the correct version of ALL the drivers that are missing or out of date on your system (this requires the Pro version – you’ll be prompted to upgrade when you click Update All).

You can also click Update to do it for free if you like, but it’s partly manual.
4) Restart your computer for the changes to take effect.
