Choppy sound often points to a software or driver conflict, not the hardware itself. This has been reported in specific scenarios, such as using a CX31993-based sound card on a Raspberry Pi Zero 2W with certain video drivers. The issue was isolated to that specific combination, with the same sound card working flawlessly on a Raspberry Pi 4B, suggesting a USB driver quirk on the lower-powered Zero 2W.

If the microphone is detected but does not pick up sound:

Given the above, you should not need to download a driver for your CX31993 dongle on a modern system. If you are trying to troubleshoot an issue where it isn't working, or if you want to be thorough, here is where you might look:

Because Conexant no longer hosts a public driver database, the most reliable method to ensure your CX31993 is functioning optimally is to . Updating Windows can often fetch the latest compatible drivers for your connected hardware. Alternatively, you can get the driver directly from the Microsoft Update Catalog.

This error typically appears on older laptops with Conexant SmartAudio HD built-in audio. It indicates that the system is looking for an internal Conexant sound card that is either disabled in the BIOS, has a corrupted driver, or is incompatible with the current OS. This is an error associated with onboard Conexant chips, not the USB-C CX31993 dongle. Nevertheless, if you encounter it while using the dongle, the solutions often overlap.

This issue is often platform-specific. On Windows, it can sometimes be fixed by changing the default audio format. If it occurs on Linux single-board computers like the Raspberry Pi, it's more complex, but switching USB ports or using a powered USB hub can help. Using high-quality USB cables can also mitigate interference and signal degradation.

Reinstall the driver via Device Manager by selecting "Uninstall device" and restarting your PC. 2. Audio Crackling or Distorted Sound

Plug your CX31993 dongle into a USB-C or USB-A port (using an adapter).

The Conexant CX31993 is one of the most popular system-on-a-chip (SoC) audio codecs found in budget-friendly USB-C to 3.5mm DAC (Digital-to-Analog Converter) dongles. Known for delivering clean, high-resolution audio (up to 32-bit/384kHz) at an affordable price, this chip is a staple for audiophiles using Android devices, iPads, and PCs.

The is a popular, low-cost USB audio codec chip often found in external USB-C to 3.5mm dongle DACs (e.g., from brands like UGreen, CableCreation, etc.).

This is the first step in troubleshooting any audio device. Go to > Sound, video and game controllers . Right-click on your CX31993 device and select " Uninstall device ." After it's uninstalled, unplug the dongle, restart your PC, and then plug it back in. Windows will automatically reinstall the driver.

Ensure the dongle is fully plugged into the USB-C port. If it still doesn't work, go to Device Manager , right-click the device, and select Uninstall Device . Unplug the dongle and plug it back in to trigger a fresh driver install. 3. Microphone Not Working
