The chip is favored for its high resolution and clean output. : Supports up to 32-bit / 384kHz PCM decoding.
: Use apps like HiBy Music or USB Audio Player Pro (UAPP) and enable "Exclusive HQ USB audio access" . This bypasses the Android OS audio stack, which often forces poor resampling and volume-scaling issues, allowing for bit-perfect playback directly to the DAC. 2. Clipping and Output Limitation cx31993 datasheet fix better
Users often report static or distortion at low system volumes on Android. The chip is favored for its high resolution and clean output
: Reaches up to -128dB , providing a very quiet background for sensitive IEMs. This bypasses the Android OS audio stack, which
: Approximately 0.0003% (-95dB), ensuring minimal harmonic distortion.
: Plug a high-impedance adapter or leave the headphone plug "open" (partially inserted) when first connecting the dongle to your device. Once the device recognizes the DAC, fully plug in your actual headphones to bypass the auto-gain limitation and potentially double the output power. 3. Clicking or "Circuit Ticking"
