Right now, it only support 8, 16, 24, 32 and 64 bits/sample. Clean
patches adding support for other formats would certainly be accepted as
long as the format is sample based and the interleave element doesn't
need to know anything more than the sample size.

That said,
"audio/x-adpcm,channels=1,endianness=(int)1234,width=(int)4,depth=(int)4,signed=true,rate=9600"
are not GStreamer caps (they look link 0.10 audio/x-raw-int caps?).
