Key Workflow: Linear PCM stereo stereo sound card for professional stereo audio workstations

This will enable your computer to communicate with audio devices such as speakers and sound cards. It is important to have a 64-bit version of a Windows operating system installed in your computer before downloading Realtek HD Audio Drivers x64. It can either be Windows Vista, Windows 7, Windows 8, or Windows 10. LoLa280 is a low profile professional linear (PCM) multichannel sound card based on the PCI Express bus interface. It is a reference sound card for professional audio recording systems for courtrooms, parliaments and other conference centers, and for audio logging and archiving systems for radios or safety organizations.

VX222e-S is a professional linear (PCM) stereo sound card based on the PCI Express bus interface. It is designed for use in any professional PC-based audio system running under Windows and requiring balanced analog and AES/EBU connectivity.

This Realtek Audio Driver for Windows 10 64 bit will install for many laptop (notebook)/Desktop computers that use the Realtek sound chip. This driver is only for the 64bit version of Windows. Some versions of Windows have generic or older OEM drivers included with the system. It is important that you use the latest audio drivers because you will get some extra feature that might not be.

At a glance

VX222e-S is the reference stereo PCM sound card designed for operating in continuous 24/7/365 use-environments as part of professional audio systems. It can be used with software applications based on standard driver interfaces such as WDM Kernel streaming, DirectSound, Wasapi, and ASIO for Windows. Compared to VX222e, it adds an AES11 sync input, a hardware sample rate converter on the AES/EBU input, and a word clock synchronization input.
