The result is high-quality PC-based audio that delivers a seamless convergence of digital entertainment between the PC and consumer electronic devices. While the Microsoft driver is expected to support basic Intel® High Definition Audio (Intel® HD Audio) functions, codec vendors are expected to differentiate their solutions by offering enhanced Intel® High Definition Audio (Intel® HD Audio) solutions. Microsoft has chosen Intel® High Definition Audio (Intel® HD Audio) as the main architecture for their new Universal Audio Architecture* (UAA), which provides one driver that will support all Intel® High Definition Audio (Intel® HD Audio) controllers and codecs.

Intel® 915G, 915P, 915GV, 915GL, and 915PL Express ChipsetsĬonsumers also want the ability to play back two different audio tracks simultaneously, such as a CD and a DVD, which can't be done using current audio solutions. Intel® High Definition Audio (Intel® HD Audio) features multi-streaming capabilities that give users the ability to send two or more different audio streams to different locations at the same time, from the same PC.

This increases the odds of audible audio cracks appearing when the CPU is busy and unable to keep up. Since the application reduces audio sample buffer size, the buffer runs out faster and needs to be refilled more frequently. We make use of this Audio Engine property by starting a rendering stream which requests the minimal buffer size that is supported by the audio driver. In that case, all applications that use the same endpoint (device) and mode (either exclusive or shared) will automatically switch to that small buffer size. However, if one application requests the usage of small buffers, then the Audio Engine will start transferring audio using that particular buffer size.

The resulting executable will be placed inside real-app/build/Debug/ folder.Īs described in Mirosoft's Low Latency Audio FAQ section, by default, all applications in Windows 10 use 10ms buffers to render audio.

Right-click on the real-app project in the Solution Explorer and select Build.

#High definition audio bus driver windows 10 latency install#

Install CMake 3.12 or later and configure your PATH environment variable to find cmake if necessary.

Make sure Microsoft Visual Studio 2017 is installed and updated.

-tray Launches the application minimised to the system tray.

The latency reduction is in effect as long as the application is kept running.

If asked to reboot the system, select Yes to reboot.īe careful: the new driver might reset your volume to uncomfortably high levels.

If a window titled 'Update Driver warning' appears, click Yes.

Select High Definition Audio Device and click Next.

Select Update driver -> Browse my computer for driver software -> Let me pick from a list of available drivers on my computer.

In the next window, go to the Driver tab.

Under Sound, video and game controllers, double click on the device that corresponds to your speakers.

Install Windows' in-box HDAudio driver (optional, might improve latency):.
