The reason it is that way is because it duplicates windows
behavior exactly.  Run the same tests with a windows msacm32.dll
any you get the exact same errors.

The problem is that wine's wave mapper expects msacm to
do the right thing but microsoft's msacm doesn't.  Microsoft
states that you must check the amount of data converted because
there is no guarantee that it will be the amount requested.  You
may need to do another conversion on the remaining data to get
it all.  Thats what the wave mapper needs to do to get all the data.
