The Burr Brown Japan PCM2702 is a USB audio device used in equipment that converts digital sound from a computer into analog audio. Its driver allows Windows to recognize the connected hardware and make it available for sound playback. On Windows 11, 10, 8, and 7, compatible PCM2702-based equipment typically uses the operating system’s built-in USB audio support, so a separate manufacturer driver may not be necessary.

Key Features

• USB audio recognition: Helps Windows identify the connected PCM2702-based device as an audio playback endpoint.
• Stereo sound playback: Supports sending computer audio to the device for conversion and output through the connected audio equipment.
• Windows sound integration: Makes the device accessible through standard playback settings, including default output selection and application audio routing.
• Straightforward setup: Compatible hardware can usually be configured automatically through Windows USB audio support without a dedicated installer.

How to Install

1. Connect the audio device. Plug your Burr Brown Japan PCM2702-based equipment into an available USB port. If the equipment requires external power, turn it on before continuing.

1. Allow Windows to detect it. Wait for the operating system to configure its built-in audio driver. Check Windows Update if setup does not complete automatically.

1. Confirm whether an additional download is needed. If the equipment manufacturer provides a driver package, verify that it matches your exact product and your version of Windows 11, 10, 8, or 7. A chipset name alone does not guarantee package compatibility.

1. Install the applicable package. If a separate driver is required, extract the downloaded files and follow the supplied instructions. Restart your computer if prompted; otherwise, proceed with the automatically installed driver.

1. Select and test the output. Open Windows sound settings or the Sound control panel, choose the USB audio device as your playback output, and play a short audio clip. If sound is missing, check the volume, output cables, and selected playback device before reinstalling anything.

Common Issues and Fixes

• Device not detected: PCM2702 is a USB audio DAC, so use a data-capable USB cable and a direct motherboard port—not a charge-only cable or unpowered hub. Check Device Manager for “Unknown USB Device” or “USB Audio Device,” and test another PC to rule out cable/port faults.
• Install fails or no sound: Windows normally uses the built-in USB Audio Class driver. Don’t force an old vendor package in compatibility mode; run any installer as administrator and reboot. Select the PCM2702 USB Audio device as default playback and use 44.1/48 kHz.
• Version conflicts: If an old PCM2702/vendor driver remains, uninstall the device and delete its driver package in Device Manager, reboot, and let Windows reinstall the native USB audio driver. Avoid stacking third-party audio drivers.
