Please describe the problem:
It is not possible to create a source element (based on audiosink) that has 
following caps:

"audio/x-alaw, "
"rate = (int)8000, "
"channels = (int) 1"

"audio/x-ulaw, "
"rate = (int)8000, "
"channels = (int) 1"

If such element is tried to be made, gstringbuffer.c throws floating point 
exception because there is division by zero situation.


Steps to reproduce:


Actual results:


Expected results:


Does this happen every time?
