I am looking for a way to pipe audio from my computer through a usb into a call that is being made by the fastrack supreme 20. The end result of this is to hopefully have a mic/speaker hooked up to my computer so that I can make voice calls with the fs20. I recognize that I could use the serial port for this but it’s too bulky, plus I already sprung for the usb port so why not use it? If anyone has any ideas of how this could be accomplished, or even have speech recorded on the computer before-hand and then send it through usb, I would greatly appreciate it. Thanks in advance for your help.
