allows for direct hardware volume control, unlocking the full 2 Vrms output. FreeBSD Auto-Config: For those using it on FreeBSD, adding hw.snd.default_auto=2 /etc/sysctl.conf
If you are integrating the chip into a custom build (like a Framework expansion card), you might notice high-frequency noise (above 200kHz). cx31993 datasheet fix better
The Conexant CX31993 is a high-performance USB-C DAC/Amp chip widely used in ultra-portable dongles (often branded as "CX-Pro" or "Abigail"). While it is praised for its high sampling rate and low cost, users often seek "fixes" for issues like high-frequency harshness or low driving power for demanding headphones. These specs are standard across most CX31993-based devices: Resolution: Up to 32-bit / 384kHz PCM. Signal-to-Noise Ratio (SNR): >128dB. Dynamic Range (DNR): >120dB. allows for direct hardware volume control, unlocking the
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. While it is praised for its high sampling
