If you are seeing in your device manager, it typically refers to a generic driver for inexpensive USB-C to 3.5mm headphone adapters (DACs) or USB sound cards based on the Airoha AB13X chip .
Audio artifacts are typically caused by resource conflicts, buffer underruns, or power-saving features.
The AB13X refers to a series of DAC chips (likely produced by Airoha Technology, a subsidiary of MediaTek) commonly utilized in low-cost USB-C to 3.5mm headphone adapters.
Everyday voice chat and casual gaming. When a Dedicated/Proprietary Driver is Required: ab13x usb audio driver
Unpowered USB hubs frequently fail to supply enough current to power high-performance audio chipsets. Connect the device directly to the PC.
While the AB13X chip is convenient, it's not without its quirks. Many issues stem from its HID (Human Interface Device) implementation or driver bugs, but most have workarounds.
Generally, these devices are designed to operate using generic USB Audio Class (UAC) drivers already built into Windows 10/11, macOS, and Android. If you are seeing in your device manager,
: The driver manages both audio output (streaming sound to your headphones) and audio input (microphone support) via the USB interface. Common Issues and Solutions
Why the driver matters A driver for an AB13x-series device is the software layer that:
Another common issue is that the beginning of a sound or word is cut off. This typically happens when the audio driver pauses to save power and doesn't "wake up" fast enough. Everyday voice chat and casual gaming
: When plugged into a PC, it may show up in the Device Manager or sound settings as "AB13X USB Audio" or "Avocent AB13X USB Audio" .
No proprietary driver is required. Both OSes have built-in UAC1 support. For Linux, you can check if the chip is detected using:
While it is intended to be simple, users frequently encounter minor hurdles with these generic chips. 1. Audio Quality and Static
