The Conexant CX31993 has quietly become one of the most popular unsung heroes of the mobile audio world. Found in countless $5 to $15 USB-C to 3.5mm dongle DACs (Digital-to-Analog Converters), this tiny chip promises high-resolution audio up to 32-bit/384kHz. It competes directly with the Realtek ALC5686 and the Apple C100. | Parameter | Incorrect (bad copies) | |

But "datasheet specs" don't always tell the whole story. Here is how to actually fix common issues and make this tiny chip sound even better. 1. The Real "Fix": Add the MAX97220 Amp But "datasheet specs" don't always tell the whole story

Some batches enumerate as “Conexant USB Audio” without a unique PID/VID.
