This means there is a problem with the caps/formats, something is not
compatible.

I'm guessing the output of wavparse is not compatible in some way
(format, sample rate, number of channels) with what rtpL16pay requires
when forced to those output caps.

Add   ... ! wavparse ! audioresample ! audioconvert ! rtpL16pay ! ..
