Despite the stellar specs, real-world performance varies wildly depending on the product's (PCB design, soldering quality, shielding) and the host device (phone, PC, Raspberry Pi).
If your CX31993 dongle is buzzing, disconnecting, or sounding "thin," a software fix usually exists. Do not throw the dongle away.
~117 dB to 124 dB (depending on implementation) Total Harmonic Distortion (THD+N): -95 dB (~0.0015%) Output Power: 1Vrms @ 32 Ohms (roughly 31mW per channel) Interface: USB 2.0 High-Speed (Type-C) cx31993 datasheet fix better
Most problems reported with CX31993 devices do not stem from the Conexant chip itself. Instead, they are caused by by white-label manufacturers trying to minimize costs.

The good news is that the community of users and testers has, in the absence of official data, reverse-engineered much of the chip's behavior. So, while we can't provide the datasheet itself, this guide serves as the next best thing: a practical, data-driven manual for getting the best out of this popular chipset. in the absence of official data
: Negates the need for massive, bulky DC-blocking capacitors, which keeps the dongle's profile remarkably slim. Common Limitations and Engineering Faults Any link to the cx31993 datasheet? - Facebook

Configure your music players to use WASAPI (Exclusive) or ASIO output modes. This guarantees that if you play a 24-bit/96kHz file, the CX31993 shifts its hardware clock to exactly match that rate without software degradation. Impedance Matching and External Amps
