ViviAudio
ViviAudio is a HAL (Hardware Abstraction Layer) driver for macOS CoreAudio, the system-level audio framework that manages audio I/O, routing, and device enumeration across the operating system. HAL drivers are low-level components that allow third-party audio hardware (microphones, speakers, interfaces, synthesizers) to integrate directly with macOS's audio subsystem, enabling applications to discover and use the devices without separate vendor software.
AI Recommendation
1 suggestionViviAudio is a system-level audio driver component, not a standalone application, so it cannot be updated through the App Store or a generic download page. HAL drivers are managed by macOS CoreAudio itself and are typically installed and updated by the hardware vendor's official driver package or control software. Contact Vivi directly or visit their support site to obtain the latest HAL driver installer for your audio hardware. The installer will properly register the driver with CoreAudio on your system. If your driver is currently Intel-only and Apple removes Rosetta 2 in macOS 28 (late 2027), you will need a native Apple Silicon version of the driver to continue using the hardware on that release, so it is important to confirm with Vivi whether a native build is planned or already available.
