That some lengths are rounded to 0 does not in itself imply a problem.
So your post does not explicitly identify any problem that would need
fixing. Is the issue that _all_ calls are rounded to 0, and as a result
no sound plays? If so then the question is what audio parameters trigger
such behavior and how you end up with such values.
