    After that, the sound doesn’t play (only an error message) until I reboot the system. Is it possible to have sound quickly and without reboot? How could I miraculously avoid such mistakes?

    Environment: Windows 7, x64 on Lenovo T420. This usually happens when plugging in or unplugging a USB headset (Plantronics .Audio 655).

    DirectSound is generally a legacy software component of the Microsoft DirectX library set for some Windows operating systems, replaced by XAudio2. It offers low latency to interface with sound card drivers written to support Windows 95 through Windows XP and can therefore handle mixing and splitting multiple audio streams. Directsound was originally written for Microsoft by John Miles.[1]

    In addition to providing the important service of routing audio data to an MP3 card, DirectSound offers other important features such as recording and mixing, adding sound effects (such as reverb, echo, or flanger), using faster hardware buffers in Windows 95 in XP, and positioning sounds in open 3D space. DirectSound also mCan record sounds from a microphone or other input and monitor for recording issues while recording audio.[2]

  • After many years of development, DirectSound is now an evolving API and offers many other realistic features, such as the ability to play high-resolution multi-channel sounds. Although DirectSound was designed for use in games, today it is used to reproduce sound in real sound applications. DirectShow uses the sound acceleration capabilities of the DirectSound components if the intelligent driver detects and provides the sound acceleration capabilities of the sensitive hardware card.[3]

    Specifications

    DirectSound is a user-mode API that provides an interface between tasks and the sound card driver, allowing applications to generate sounds and play music.

    DirectSound was considered revolutionary when it was introduced in 1995 because it included multiple simultaneous audio channels and multiple applications that allowed the sound card to be polled at the same time. PerThese game developers need to implement their own powerful sound rendering engine in the software.

    DirectSound offers sample rate and audio mix updates (volume to pan) for an unlimited number of audio file sources; However, the practical limits are undoubtedly the number of natural sound sources in the equipment and the power of PC mixers.

    DirectSound’s architecture uses a “ring buffer” to give the impression of continuous looping playback. The application programmer creates the sound, then you must continuously buffer its state with the “read cursor” and update it with the “write cursor”. There were two types of buffers – a true “streaming” buffer which contains normal sounds such as background music, and a new “static” buffer which contains compact sounds.

    On supported sound cards, DirectSound will evaluate the use of “hardware accelerated” buffers created by my husband and me, for example. those that can either be permanently savedAnanes in local sound memory, on a Visa card, or accessed from system memory via the type of sound card. If hardware acceleration is not available, DirectSound will create sound buffers in system memory and simply use the mixing software.

    Some “wavetable” quality cards from the late DOS era, such as the Sound Blaster AWE32 and Gravis Ultrasound, contain special DSPs borrowed from automatic musical instruments. These cards had limited memory that could be used to buffer multiple audio streams and interconnect those cards, usually offloading the processor and greatly improving sound quality. However, this was only plausible in DOS, which currently programs the hardware directly, and full “hardware acceleration” in local memory was never performed on these cards due to the complexities of double buffering. Newer cards such as Sound Blaster Live!, Audigy and X-Fi can directly access this memory buffering system.

    DirectSound3D

    DirectSound3D (DS3D) has always been an extension of DirectSound, introduced in 1996 with DirectX 3, with the main purposestandardization of popular 3D music on Windows. DirectSound3D gives software developers the ability to use sound by writing it once as a single sound API that instead links multiple times to rewritten code, works – for any sound card vendor.

    In DirectX 5, DirectSound3D received support related to sound cards that use third-party 3D audio algorithms to properly accelerate DirectSound3D using methods permitted by Microsoft.

    In DirectX 8, DirectSound and then DirectSound3D (DS3D) were officially merged and named DirectX Audio, although the API is still commonly referred to as DirectSound.

    EAX

    EAX is an And directsound DirectSound3D extension that enables hardware-accelerated sound effects processing for these buffers.

    Operating System Support

    Windows 95

    In Windows 95, prior to version 2000 and Me, the DirectSound mixer component and sound card drivers were permanently implemented as kernel-mode VxD drivers (Dsound.vxd), providing direct access to the commonly used main buffer. sound equipment and therefore a particularly low possibilityThere is a significant delay between the user mode API and the underlying hardware, and in some cases causes instability and additional blue screen errors.

    Windows 98 introduces WDM Audio and the Kernel Audio Mixer (KMixer) driver, which provides simultaneous digital communication, routing, and processing of audio streams with improved quality of audio rate conversion, also taking into account kernel streaming. In WDM, DirectSound sends evidence to the KMixer software. Windows 98 Second Edition improved support for WDM audio by adding DirectSound hardware buffering, DirectSound3D hardware abstraction, KMixer sample rate recovery (SRC) for streams, Capture multi-channel audio guide, and the introduction of DirectMusic. If the underlying audio hardware supports hardware switching (also known as hardware buffering or DirectSound hardware acceleration), DirectSound buffers directly on the playback device if necessary.
