The "CX31993" datasheet "fix" is a case study in vendor obfuscation. The "better" version of the documentation exists not as a paper manual, but as the collective knowledge base of the Linux audio driver tree. If you have a specific electrical issue with this chip, you may need to trace the schematics of a working device rather than relying on the official documentation.
On certain devices, the issues are purely driver or system related:
No EEPROM? The chip falls back to default—fine for most uses, but avoid if you need Windows driver matching.
After reverse-engineering several dongles and consulting application notes, here’s how to in the CX31993 datasheet for better performance and reliability.
I cannot directly "fix" the datasheet because I don't have live access to external files or proprietary documents. However, I can tell you what is likely wrong with common copies of the CX31993 datasheet and give you the corrected/verified specifications based on actual measurements and application notes.
