Intel High Definition Audio (IHDA) (also called HD Audio or development codename Azalia) is a specification for the audio sub-system of personal computers. It was released by Intel in 2004 as the successor to their AC'97 PC audio standard.
Common device driver compatibility issues include: a 32-bit device driver is required for a 32-bit Windows operating system, and a 64-bit device driver is required for a 64-bit Windows operating system. 64-bit device drivers must be signed by Microsoft, because they run in kernel mode and have unrestricted access to the computer hardware. For ...
Three classes of audio devices are supported by default: USB, IEEE 1394 , and Intel High Definition Audio, which supports PCI and PCI Express. Starting with Windows Vista, Microsoft requires all computer and audio device manufacturers to support Universal Audio Architecture in order to pass Windows Logo certification.

Currently only Microsoft Windows (AMD/Intel x86-64) is supported by the ASIO SDK. Microsoft announced to incorporate ASIO into their USB Audio Class 2 driver for their Arm64 architecture. [5] While originally supporting MacOS, the introduction of Core Audio with macOS X made ASIO support for this OS unnecessary.
The resulting implementation of the IA-64 64-bit architecture was the Itanium, finally introduced in June 2001. The Itanium's performance running legacy x86 code did not meet expectations, and it failed to compete effectively with x86-64, which was AMD's 64-bit extension of the 32-bit x86 architecture (Intel uses the name Intel 64, previously ...
Driver compatibility was less of a problem with open-source drivers, as 32-bit ones could be modified for 64-bit use. Support for hardware made before early 2007, was problematic for open-source platforms, [citation needed] due to the relatively small number of users. 64-bit versions of Windows cannot run 16-bit software.
High-resolution audio (high-definition audio or HD audio) is a term for audio files with greater than 44.1 kHz sample rate or higher than 16-bit audio bit depth. It commonly refers to 96 or 192 kHz sample rates. However, 44.1 kHz/24-bit, 48 kHz/24-bit and 88.2 kHz/24-bit recordings also exist that are labeled HD audio.
