The system software accommodates two discrete output configurations:
An updated, dedicated driver unlocks native Audio Stream Input/Output (ASIO) support, bypassing the Windows mixer for lower latency and bit-perfect playback.

If you are looking to ensure your SA9123L driver is properly updated: Check Device Manager
Disconnect the DAC. Plug it into a different USB port—preferably a USB 2.0 port , as the SA9123L architecture can occasionally conflict with USB 3.0/3.1 controllers. Avoid using unpowered USB hubs. Optimizing Your Audio Settings After the Update Avoid using unpowered USB hubs
: Ensures the audio stream reaches the DAC without being resampled or altered by the operating system.
Unlike older USB interfaces that heavily compress audio pipelines, the SA9123L relies on high-speed hardware-level streaming. This bypasses the noisy processing loops inherent to standard computer motherboards. Operating System Compatibility & Native Support This bypasses the noisy processing loops inherent to
