I want to set up an usb interface ( presonus 2x2 ) to use software ( amplitube etc.l ) im buying next month but i dont know if its possible with my current computer setup . i have 2 krk studio monitor , a mixer . i uploaded an image of my setup . Basically LApTOP+playstation + tv Receiver are connected in the HDMI IN of the TV . And the Samsung audio out of the tv goes into a mixer and i have my active studio monitors connected in the mixer . that way . laptop + playstation + tv console all get out in through my studio monitor . So the sound device use on my laptop is "Samsung tv" since its plugged hdmi in to the Samsung . now if i use an interface... i have a loud noise and i cant run any ASIO on amplitube and i have crazy latency . is there a way to use the usb interface correctly so i dont have latency issued . Thank you. http://fr.tinypic.com/r/2potg5j/9 edit : After a few search .. i think my best option would be to plug the studio monitors in the usb interface so that the laptop sound would come from studio monitor . for the tv / playstation .. i can use the tv volume for that .. wouldnt be a big compromise. now is there way to send the laptop screen to a larger screen via HDMI without sending the audio . when i plug a hdmi ... the audio is set by default to SAMSUNG HDMI OUT ... i would just have to disable that and use the interface as a sound card ?
