Given the age of Prime, I suspect it’s unlikely that you will be able to access a suitable driver in Windows 11. That is, whatever driver was originally provided with Prime will now be out of date - and will be incompatible with the latest WndowsOS.

An alternative method of connection is to buy a SOtM sMS-200 Network Audio Bridge. Connect it between your network hub or router and Prime. You will then no longer have to rely on Windows for directly connecting to Prime.
