<div>There were some settings on the MythTV general setup screen. I can't remember them off the top of my head, but I'll post them when I get home.</div>

<div>You probably have already seen this, but in alsamixer there are three items labeled something like IEC958. The first one needs to be checked, the second one (IEC958 Output I believe) should be unchecked and the one with a slider should be all the way down. I believe I turned all four of those DXS sliders up.

<div>My audio setting in xine is set to Passthrough.</div>
