Alright, I changed them to fixed caps, and now it appears to give correct audio
output but in the debug output it continually prints

0:00:26.052693439  8383      0x2cd13e0 WARN         basetransform
gstbasetransform.c:1037:gst_base_transform_acceptcaps:<audioconvert0> transform
could not transform audio/x-raw-int, endianness=(int)1234,
signed=(boolean)true, width=(int)32, depth=(int)32, rate=(int)8000,
channels=(int)2 in anything we support (othercaps (NULL))


In addition, if I make this change in my larger program, it shows that when the
caps are reset the uridecodebin fires a drained signal, which is undesirable as
that is how I know that stream is ended and can be discarded. When setting the
caps in this case, the following appears in the debug output:

My debug level is GST_DEBUG=*:3,GST_STATES:0, and the fixed caps are
"audio/x-raw-int, rate=(int)44100" and "audio/x-raw-int, rate=(int)8000".  Let
me know if you require any additional information.
