Summary:                    [patch] Audible clicks when playing a file with
header larger than AU_HEADER_SIZE
Description: 
format_pcm.c:check_header ignores the defined header size in the file and
instead simply expects the header to be AU_HEADER_SIZE bytes long.  If the
headers are actually longer than that, this causes the audio to "click"
since the rest of the headers are played as part of the file.

I ran across this as sox adds it's own "Processed by SoX" comment to the
header when it transcodes files.

Use the advertised header size in .au files instead of just assuming they
are 24 bytes (the minimum).
