I've got a following problem: I'd like to record audio and play some other audio simultaneously. This kind of function is often named full-duplex.

I think Nokia phones have this kind of functionality, because of the basic call function. But that works on lower level software compared to what public SDK offers, I think.

Is it possible to create this full-duplex -functionality with public SDK's APIs and if is, how do you do it?

I have introduced myself with the CMMFDevSound class. It seems to have such features, but I still have some problems. Could you help me?
