: A frequent complaint involves Windows 11 detecting the device as 16-bit rather than the advertised 32-bit. Low-Volume Distortion
Developers for the Framework Audio Expansion Card (which uses this chip) have noted Class G amplifier noise over 200kHz, suggesting a low-pass filter for sensitive DIY applications. Resources: Cx31993 Datasheet Fix
This article serves three purposes: first, to reconstruct the missing technical datasheet details from community reverse engineering; second, to diagnose why your CX31993 is failing; and third, to provide a step-by-step firmware and driver fix guide. : A frequent complaint involves Windows 11 detecting

While a direct PDF download for a "datasheet fix" is not publicly hosted by Synaptics, technical parameters are widely documented by manufacturers like and Audiocular who implement the chip: Key Technical Specifications DAC Sampling Rate: Up to 32-bit / 384kHz.
Engineers often report noise spikes in the 200kHz+ range, which can interfere with sensitive measurement equipment or oscilloscope music. Any link to the cx31993 datasheet? - Facebook
