Maybe need libsndio.a static build? about ffmpeg-static

[kuh3h3]

In my system , there is shared lib.

kuh3h3@reandro:~/ffmpeg-static/build$ ls -al /usr/lib//libsndio
-rw-r--r-- 1 root root 58832 11월 25 2016 /usr/lib/i386-linux-gnu/libsndio.so.6.1
lrwxrwxrwx 1 root root 15 11월 25 2016 /usr/lib/x86_64-linux-gnu/libsndio.so -> libsndio.so.6.1
-rw-r--r-- 1 root root 55520 11월 25 2016 /usr/lib/x86_64-linux-gnu/libsndio.so.6.1

I have the same issue even though libsndio-dev and libsndio6.1 are installed on my system.
Libraries:
~/ffmpeg/static_build$ ls /usr/lib/x86_64-linux-gnu/libsn
libsnappy.so.1 libsnappy.so.1.3.0 libsndfile.so.1 libsndfile.so.1.0.25 libsndio.so libsndio.so.6.1 libsnmp.so.30 libsnmp.so.30.0.3
