I have used several different RealTek built in soundcards with both PT and RB (virtually identical engines) and have been able to do what you want to do. There may be different RealTek designs out there, but if your computer is even "relatively" new, it should be able to do this.

I suspect a setting somewhere is preventing this.

Please check, inside of RealBand, Prefs -> 2Audio -> and about halfway down the window that opens on the LH side, see if "Full Duplex(Record/Play at same time)" is checked to true.

If it is, try UNchecking it, say okay, then go right back and check it again and say Okay. Might be "stuck" somehow...
