Enable the -debuginfo repos and install the libsndfile-debuginfo package:

    # yum --enablerepo extras-debuginfo install libsndfile-debuginfo

Find out if selinux is in permissive mode:

    # sestatus

Find out if selinux is denying access by looking in the log, either
/ver/log/messages, or if audit is installed /var/log/audit/audit.log.
