I recent bought a "Sound Blaster X-Fi Surround 5.1 Pro" (external sound card)to use with my surround sound desktop speakers on my laptop. Of course my laptop only has one head phone port and the speakers have three 3mm jacks that need to be plugged in. Anyway, the sound card will only work when plugged into a USB port on a computer. It seems to play music via the USB cable.
The sound card does have a line in which I could plug into my tv/laptop/phone. I dont want to have to hook the sound card up to my laptop if i just want to listen to music on my phone. I was wondering if it's possible or if anyone could point me in the right direction, if there's a way to program a microprocessor have the software or drivers loaded onto it. So when its plugged into a custom circuit the microprocessor acts as if was the computer so I can just use the line in
Thanks in advance
