Why is the audio stuttering, cracking, or choppy in the software preview?

1. Make sure the version of firmware of your capture card device is up to date. 

 

2. Using a USB capture card? It might be a USB 3.0 compatibility issue.

Some AMD motherboards (such as B350, B450, B550, B650, etc.) may experience issues like audio dropouts or frame drops when using USB 3.0 capture devices. This is often related to the design of the motherboard’s USB controller. In particular, ports using non-native controllers (such as ASMedia or Renesas) may have reduced compatibility with high-bandwidth video devices.

Please try the following troubleshooting steps:


1 Use the rear USB 3.2 Gen1 / Gen2 ports directly on the motherboard. Avoid front panel USB ports, USB hubs, or any ports connected to ASMedia/Renesas host controllers. Please try all available USB ports if possible, as not every port is necessarily using an ASMedia or Renesas host controller.
2 Update your BIOS and AMD chipset drivers. This can help improve USB stability.
3 Enter the BIOS and disable power-saving settings, such as “Global C-State Control” and “USB Standby Power.”
4 If the issue persists, try testing the capture card on a different motherboard to determine whether the problem lies with the capture card or the system.

If you’re unsure which USB controller your ports are using, we recommend checking your motherboard’s manual or contacting the manufacturer for assistance.

Note: Since using the only 10Gbps Type-C port on your motherboard is required for the GC553G2, please try the following workaround if you encounter issues:
Connect the Line Out of the GC553G2 to the Line In of your PC using the included audio cable. This can help eliminate static interference on the USB-C ports of certain motherboards.


3. This may be due to built-in AI noise reduction on your platform. Please turn off all AI noise reduction on the software such as NVIDIA Broadcast below:

Choose All off on Microphone array in Realtek Audio Console





As for other PC manufacturer like HP or Dell, you can see our troubleshooting tutorial video.

For ASUS motherboard or laptop, you can also choose "off" on their software
