: 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
Some batches enumerate as “Conexant USB Audio” without a unique PID/VID. cx31993 datasheet fix better
The CX31993 has automatic impedance detection (low gain for <30Ω, high gain for >100Ω). Without the datasheet, we cannot manually set gain. However, : Use apps like HiBy Music or USB
