The Edirol UA 20 (MME) driver lets Windows communicate with your Edirol USB audio interface for recording and playback. It makes the interface available to compatible audio applications through the Windows MME audio system, so you can select it as an input or output device.

Key Features

• Audio input and output access: Allows compatible software to use the UA 20’s connected audio sources and playback outputs.
• MME application support: Provides access through the MME driver interface used by many Windows recording programs, audio editors, and playback tools.
• Device recognition: Helps Windows identify the interface and expose its available audio connections to supported applications.
• Recording and playback configuration: Enables you to select the Edirol interface in your software and adjust available audio settings for your workflow.

How to Install

1. Check the driver requirements. Before downloading, confirm that the package explicitly supports your version of Windows 11, 10, 8, or 7 and your system architecture. Older audio hardware may require a specific driver release; compatibility should not be assumed across all Windows versions.
2. Prepare the interface and computer. Close audio applications and disconnect the UA 20 unless the package instructions say otherwise. If replacing an existing driver, follow the supplied removal guidance.
3. Run the installer. Extract the download if necessary, then launch the setup program with administrator permissions. Follow the prompts and approve installation only if you trust the package’s source and publisher.
4. Connect the hardware when prompted. Plug the interface directly into an available USB port and allow Windows to finish detecting it. Restart the computer if requested.
5. Select and test the audio device. Open your recording or playback application, choose its MME audio mode where applicable, and select the Edirol UA 20 input and output. Test playback and a short recording, checking cables, levels, and application settings if you hear no sound.

Common Issues and Fixes

• Install fails or stalls: Disconnect the UA-20 before running the installer, run it as Administrator, and temporarily disable antivirus. Reboot before connecting the interface; connecting during setup can leave the MME driver half-installed.
• Device not detected: Use a direct rear USB port instead of a hub, try a known-good USB cable, and check Device Manager for unknown or generic USB audio devices. Confirm the UA-20 is powered, then reinstall the driver if it still does not appear.
• Version/device conflicts: Uninstall older Edirol/Roland USB audio drivers and reboot. Install the matching 32/64-bit UA-20 driver only, and remove duplicate UA-20 entries in Windows Sound settings so MME apps select the correct device.
