I know there is sound, just not sure how to get it out. What I'm thinking is I don't have the correct options set in the ALSA mixer. These are all options listed using aplay -L. ALSA:dmix doesn't work, and ALSA:default behaves the same as spdif. All of this is through the spdif connection, all with the ALSA:spdif designation.
