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. MP3 playback is jittery and the level changes slightly up and down. Non digital sound plays, but here's the kicker, it's jittery. Neither HD content, nor any digital track will play.
