can aiff work without block_align ?

either way, block_duration is from the header reading
if its still accurate then using it together with 1 instead of the
matching block align is quite likely not correct
OTOH if block_duration does not represent the actual content then
the duration would only be correct by pure chance

Its a bit unfortunate that theres no usecase with an undamaged sample
which would have clear correct values

one has to work on the assumptation of a use case where the user needs
to override the codec and then ask "what is correct to do" that makes
this a bit tricky ...
