Cx31993 Datasheet Fix Better

The "CX31993" is likely a reference to the Cirrus Logic CS51983 (or the related CS4206/CS4207), a High Definition (HD) Audio Codec used in many laptops (notably Apple MacBooks and Dell machines) during the late 2000s and early 2010s. For years, Linux developers and audio engineers struggled with "broken" audio (headphone jack detection, static noise, and input gain) because the official datasheets omitted critical programming sequences known as "Vendor Specific Coefficients." The "fix" was not an official errata, but a reverse-engineering effort by the open-source community.

That’s insufficient for low noise floor. Use this proven network:
