asio4all and windows sound routing

[sm_jamieson]

My windows 10 laptop has realtek sound chips /drivers that understand ASIO so that when I have my audio interface selected in Usine,
I can also send windows sound (e.g. from youtube) to the same interface, which is useful for practice.
But if I use asio4all to talk to my interface, asio4all takes over all PC audio so nothing else can be sent to the audio interface.
Currently I have to use asio4all to connect my interface due to driver problems.

The question is this:
Is there any software / virtual audio cable etc. that can route audio from something like youtube to an audio input in Usine,
whilst asio4all is in use ?

I could then mix the youtube audio in Usine and send out to my audio interface via asio4all.
