I'd be surprised if there's a driver for a specific card, and "duplex" isn't a term often heard here. I know what you mean I think from ham radio. You want to "monitor" a recording connection I think. You can take an input connection and attach an output to it. Try man alsaloop or maybe aconnectgui. And see https://www.alsa-project.org/main/index.php/Asoundrc Jack and Pulseaudio are maybe more friendly but it's probably possible with just alsa. I've never had reason to try to do it.
