Loopback Windows 10 / Cubase

Is there a possibillity to record Browser Sound/ Windows Sound / Skype… any application ?
Loopback is on CH 1-2 but still no possibility to record in Cubase ? My 15 years old creamware card can do ? Anybody here can show me a way to do this ? Sur i can put output to input via cable. But this cant be right for a 2300.- Euro Device or ?

Please help if you know how to !!

thx a lot
