EpsonProjectionAudio
EpsonProjectionAudio is an audio hardware abstraction layer (halDriver) plugin for macOS CoreAudio that enables audio input/output routing through Epson projectors or compatible Epson audio hardware. It integrates with the system's CoreAudio framework to present Epson devices as audio endpoints within macOS, allowing applications to select an Epson device as their audio input or output source. The plugin is installed as part of Epson's device drivers or utilities when users set up compatible projection or audio equipment.
AI Recommendation
1 suggestionEpsonProjectionAudio is not a standalone application but a system-level CoreAudio plugin managed by macOS. It is installed and updated as part of Epson's device driver package, not through the App Store or any separate application. To ensure this plugin receives any native Apple Silicon updates, install or update Epson's official device drivers for your projector or audio hardware via Epson's support website or the vendor's included installer utility. If you are running an older Intel-only version of this plugin, updating the parent Epson driver package will provide the native build. If Epson has not yet released a native Apple Silicon driver for your specific device, contact Epson support to check the roadmap — given that Rosetta 2 is being removed in macOS 28 (September 2028), it is important to confirm native support is available or planned before that deadline.
