Oka Mirror Audio Driver
Oka Mirror Audio Driver is a system audio plugin (HAL driver) for macOS that enables audio mirroring functionality in the Oka Mirror app. It integrates with macOS CoreAudio to capture and route system audio to external displays when mirroring the screen to a TV, allowing synchronized audio output alongside video. The driver requires microphone access permission but does not actually use the microphone — it merely taps the system audio stream to relay it to the mirrored destination. This driver is typically installed as part of setting up the Oka Mirror app for screen and audio sharing.
AI Recommendation
1 suggestionOka Mirror Audio Driver is a system audio driver component that ships as part of the Oka Mirror installation from Existential. It is not a standalone application and cannot be updated separately through the App Store or a generic download. To ensure you have the latest version of the driver, visit okaapps.com and download the current Oka Mirror installer, then run it to update both the main app and the audio driver together. If you are already running Oka Mirror and the audio driver was installed alongside it, the standard application update mechanism for Oka Mirror will handle driver updates as well. Because this is a system-level component, you may need to grant microphone access permissions in System Preferences → Security & Privacy → Microphone after installation, even though the driver itself does not record microphone input — this permission is required to access the system audio stream that it mirrors.
