For simple recording, try MME drivers (as latency wouldn't matter) and they tend to be more stable. When using MME there is usually no sense in tweaking latency settings.

If ASIO is required, then settings on all devices become more relevant.

I'm having a serious problem with recording of BIAB songs with real tracks ..

How exactly are you trying 'recording of BIAB songs with real tracks'?
Your initial question leaves me puzzled. You should be able to render the BiaB file without concern for MME/ASIO
If you are actually 'recording' tracks you may want to try Realband instead.
