Yes, with some caveats. There is no universal standard Line Level for PC sound cards. Between the Line Level and Mic Level settings available in the Espresso, you will likely find one that works well with your PC. Some cards are vastly configurable and it may take some time to find the settings that work best for you. It may take some fiddling, but so far our customers tell us it is worth it big time.
Say Swat, you lucked out with an awesome Auto-Monster-Icon. 😉
