format: Add correct sample spec conversion for E-AC3

Browse source 
IEC61937-encapsulated E-AC3 frames contain 6 audio blocks per substream,
which corresponds to 1536 samples contained a 24576-byte frame. To cope
with this, we maintain the s16le stereo sample spec, but quadruple the
sample rate so that the conversion remains accurate.
