From the "pactl list cards" under Precise, I see that all the profiles with "iec958" are missing the "40" and are only "stereo" profiles. I think that's part of the problem since on Lucid I need to use the "output:iec958-surround-40+input:iec958-stereo: Digital Surround 4.0 (IEC958) Output + Digital Stereo (IEC958) Input (sinks: 1, sources: 1, priority. 155)" profile to have the sound working.
