afaik the workaround in http://svn.mythtv.org/trac/ticket/5598 is
re-mixing everything to stereo on the spdif device.
Doing this WILL make mono audio streams work (since they're upsampled
to stereo). But it will also downsample all 5.1 streams to stereo.
(Please, correct me if I'm wrong here)
I don't think thats what you want if you're using AC-3 passthrough -
since you're losing your surround sound then.
