I tried through the share plugin. did not work either.
maybe i'm going about this the wrong way...
i have an capture input that is from the output mixer. presumably, this
outputs 5.1 surround, so maybe i can copy from this to the iec958 output? of
course, one has to wonder if the passthrough would still work. and the
softvol still could have trouble... ?
