PBAX316-90108MV1 USB Desktop Hi-Fi Audio Decoder Evaluation Kit User Guide

First Use

After receiving the evaluation board, users can install and configure the environment according to the following steps for evaluation.

Driver Installation

The evaluation board supports USB UAC 2.0 for audio playback. Windows 10 build 1809 and later versions have native USB UAC 2.0 drivers. However, the native driver can only play audio with a maximum sampling rate of 384kHz. To evaluate 768kHz sampling rate and DSD format, you need to install a third-party driver.
