This error has surfaced again. Did the patch not take?

As a recap, if the ( <-ss value> + 16) % 32 = 0, then the audio is 
corrupted when cut. Using commands of the form:

ffmpeg -ss 528.0 -t 24.0 -y -vcodec copy -acodec copy -i test.avi cut.avi

(In the above case, the audio would be garbled because 528 + 16 = 544 
and 544%32 = 0 .)
