Here's a concise, useful piece of information regarding its driver situation:
Driver status:
-
No proprietary driver is required for the CX31993 on modern operating systems.
-
It uses USB Audio Class 1 (UAC1) or UAC2 (depending on firmware), which is natively supported by:
- Windows 10/11 (built-in USB Audio driver)
- macOS (Core Audio)
- Linux (snd-usb-audio)
- Android (USB audio class support)
- ChromeOS
-
No need to install drivers from Conexant – generic OS drivers work instantly when plugged in.
Potential issue & fix on Windows:
Some CX31993 dongles are mistakenly detected as a "Speakers (Conexant USB Audio)" but may not output sound immediately.
Solution:
- Open Sound Settings → Sound Control Panel (old panel).
- Find the CX31993 device, right-click → Properties → Advanced.
- Uncheck "Enable audio enhancements" (this resolves silent output on some Windows versions).
- Also check Spatial sound is set to Off or Windows Sonic if needed.
Linux tip:
The CX31993 works out of the box. If you experience no sound on some kernels, add options snd-usb-audio index=0 to /etc/modprobe.d/alsa.conf and reboot.
