Download the audio drivers from manufacture's websites for Windows 10, if there no drivers available for Windows 10, d ownload the latest driver from the manufacturer’s website and try installing it in compatibility mode.

Using Signalink with FLDIGI by AE6XO 1. Use a custom Signalink to VHF radio cable for making the connection. Plug your radio’s speaker output into the “SPKR” jack on the back of the Signalink. Plug the USB cable into the Signalink and your computer. Drivers will automatically install.
I recently purchased an external sound card (Signalink) which connects to computer via USB port. When the signalink is connected to the USB port, Windows 10 should automatically provide a USB audio driver. That hasnt happened. In checking the device driver I find that there is no USB Audio codec on the computer.
