Comment (by Wilbert):
I don't know how to do that properly. If i just replace 00 004A 55 with 02
0012 10, Virtualdub is able to open the file and i hear the sound. But
beforehand i get a warning 'AVI: Truncated or invalid compressed audio
format detected (18 bytes, should be 20). Attempting to fix.'.
If i use AVIMux to mux the files (which does write AudioSpecificConfig and
sets cbSize=2), it plays fine in Virtualdub.
