Some people put AC3 or DTS data into 16-bit stereo PCM streams, but this
is mostly a "hack" as far as I know. This kind of mis-labelling of the
stream contents should not really be needed.

I don't think there's an iec958ac3 element yet. Alsasrc would probably
need a few fixes before this would work anyway.
