I have a laptop and am using a turtle beach USB audio card (automatically disables laptop speakers). I am looking at getting an external DAC with a USB port. Does anyone know if it is possible to use the turtle beach card and the USB port going to an external DAC for audio at the same time? The reason I want to do this is because I use the laptop for watching Divx movies in 5.1 but want to listen to music through the DAC in two channels.
