What does /etc/security/limits.conf say?

My file has this line:

"@audio - memlock 25000000"

which gives me 2.5m of non-locked memory. (at least I think
that's what it means)

Try make clean before make. If that doesn't help,
what says "sh gen_setformat_c.sh"? And which version
of libsndfile do you have?

This is probably related to the bug above, where it didn't
find a legal soundformat, and thus couldn't open a new file
with libsndfile either.
