Is it possible to have a Pi with this setup, only use a sound card for the output, not the input? I want to play music from the pi, not have it receive the music.
I'm not sure I follow what you're asking, what device do you want to play the music from and what device do you want to use for processing and what device do you want to send LED frames to?
