Two sound cards in Windows 8

I have my realtek audio working along with my audio device I use for X2. I think you need to set the CL as the default under Windows than setup your MOTU. I use the Realtek as a general purpose audio device for things like MP. Simply setup the CL first don't have the MOTU installed than after the CL is working install the MOTU. I used to do this in the past with a CL Audigy and before a CL Live and so on going back to the first Sound Blaster.

As long as your not getting any conflicts with windows using the creative and your audio apps such as sonar using the motu your best bet is to leave this configuration and use a mixer to connect your sound cards to your monitors. I learned a long time ago this configuration runs smooth for me on multiple computers and various pro audio sound cards. In other words, let windows use the on board sound card not your pro audio sound card. With this configuration I never have conflicts and can run windows media player, iTunes, sound and video in Internet explorer etc while runing Sonar at the same time. Also, make sure your pro audio apps such as sonar do not use the drivers from creative.
