What this adapter does

The Sabrent AU-MMSA adds a stereo output and a mono microphone input to any computer with a free USB Type-A port. It is built for laptop and desktop users who need a quick replacement for a broken onboard jack or an extra headset connection.

Installation experience

The device draws power from the USB bus and works without drivers on Windows 98SE through Windows 11, Mac OS 8.6 and later, and Linux. Plug it in, select it as the audio device, and it is ready. The only common issue is forgetting to set the adapter as the default playback or recording device in the operating system sound panel.

The deciding specification

It uses a USB 2.0 interface that is backward compatible with USB 1.1 and follows the USB Audio Device Class 1.0 standard. Buyers who need multi-channel surround sound or a dedicated line-level input should look elsewhere, as this adapter provides only stereo output and mono microphone input.

Questions about this item

How can I confirm the AU-MMSA is working after plugging it into a USB 2.0 port?

Your operating system should list a new USB audio device in sound settings and audio should play through the stereo output jack.

What comes in the box and what else do I need to use it?

The box contains the USB audio sound adapter only; you must provide headphones or speakers and a microphone separately.

Which version of this adapter should I choose for Windows 11 or Mac OS 8.6?

The single AU-MMSA model supports both Windows 11 and Mac OS 8.6 or above driverlessly.
