Datasheet Fix — Cx31993

Fixing issues with the CX31993 (a popular high-performance Conexant USB-C DAC chip) typically involves addressing "datasheet" errors in how the operating system or player app interprets the hardware's capabilities rather than a physical modification. 1. Fix Audio Static & Stuttering (Bit-Perfect Mode)

Many users report static or clicking when using the CX31993 on Android or Windows. This often happens because the system's standard audio driver applies sample rate conversion that clashes with the DAC's high-res hardware specs (32-bit/384kHz).

Android Fix: Use a player that supports Exclusive HQ USB Audio Access (like HiBy Music or USB Audio Player PRO).

Windows Fix: Go to Sound Settings > Device Properties > Additional device properties > Advanced. Manually set the Default Format to 32-bit, 384000 Hz (Studio Quality) to match the hardware's peak capability. 2. Resolving "Clicking" or Power Cycling

If you hear a physical clicking sound when audio starts or stops, the DAC is likely entering an aggressive power-saving "deep sleep" mode between tracks.

Firmware Fix: Some manufacturers (like VE Odo ) have released firmware updates (e.g., version 2.1+) that disable this aggressive standby to keep the circuit active.

Alternative: Keep a "silence" track playing in the background or use an app that keeps the USB bus active. 3. Troubleshooting Connection Issues

Device Not Recognized: If Windows shows an "Unrecognized Device" error, try using a different USB-C to USB-A adapter if connecting to a PC; many bundled adapters have high failure rates.

OTG Compatibility: Ensure USB OTG (On-The-Go) is enabled in your phone's developer settings if the DAC doesn't power on immediately. Technical Reference (Hardware Specs) Conexant (CX-Pro) CX31993 USB-C Amp/DAC Review

But for 99% of users, these are irrelevant.

The CX31993 is a low-power, high-performance audio codec from Conexant (now part of Synaptics). It’s famous for powering affordable USB-C dongles (like the Ablet, Ugreen, or JCALLY JM6) that support 32-bit/384kHz audio and a 114dB signal-to-noise ratio.

The Conexant CX31993 has become a ubiquitous entry-level USB audio codec, found in dozens of affordable USB-C to 3.5mm dongles. However, for months, the publicly available datasheets were either incomplete, contained conflicting pinout information, or lacked critical register maps for I²C control. Enter the unofficial “CX31993 Datasheet Fix” – a community-sourced, annotated correction document that has quietly saved hundreds of hobbyist projects.

Through years of forum trawling (Reddit r/headphones, DIYAudio, Lenovo and Dell support threads), users searching for a “datasheet fix” typically report:

None of these are solved by a datasheet. Below is the actual fix for each.

Windows aggressively saves power by shutting down USB ports. The CX31993 is sensitive to this.

Step-by-step:

After all software fixes, some CX31993 dongles are simply defective due to:

If you experience persistent hiss with low-impedance IEMs or connection drops when moving the cable, no registry tweak will help. Return the dongle and buy one from a reputable manufacturer that publishes its own application notes (the consumer-friendly version of a datasheet).
