First, a critical note: The AverMedia H727 is a legacy device (released ~2011). It uses a PCIe x1 interface and an older Conexant chipset. AverMedia officially stopped supporting this card after Windows 8.1. Therefore, finding a stable Windows 10 driver requires a specific, unofficial method.
Even with the "best" driver, you may encounter issues. Here is the fix matrix:

Do not use the installer from the CD or the automatic Setup.exe from AverMedia’s site. It will fail. First, a critical note: The AverMedia H727 is
