I know some other things get installed with the realtek audio driver like sonic radar and sonic studio, I'm not sure what all installs with it. I don't install the realtek driver I just use the jacks on the front of my case.
To your question the answer is no... I realize that there is no ASIO drivers to the RealTek chip in this MoBo... It is possible to use ASIO4ALL but have no choice to use an USB Audio Interface like m-Audio FastTrack.
