Cx31993 Datasheet Fix Hot Jun 2026

A drop from 55°C to 35°C under load.

Excessive heat is often linked to "stuttering" or "crackling" caused by high processing loads. Increase Buffer Size : If using USB Audio Player Pro (UAPP) , go to settings and increase the USB audio buffer size . This reduces the real-time processing stress on the chip.

: Playing DSD files forces the chip to work much harder than standard PCM files, leading to significantly higher temperatures (up to 50°C). 3. Power & Connectivity Fixes Avoid Fast-Charging Pass-through A drop from 55°C to 35°C under load

Finding a detailed official datasheet for the Cx31993 can be difficult as it is a legacy chip (often associated with manufacturers like Chroma or similar OEMs). This reduces the real-time processing stress on the chip

: Try plugging your headphones into the DAC first , then connecting the DAC to the device to ensure proper initialization. Alternative Recommendations :

If you are working on CRT monitors or power supplies containing this chip, be aware of high voltage risks. Capacitors can hold lethal charges even when unplugged.
