Here is what I got when I attempted to run the app under a non-root
user.

close(3) = 0
munmap(0x40018000, 4096) = 0

ioctl(3, SNDCTL_TMR_TIMEBASE, {B38400 opost isig icanon echo ...}) = 0
old_mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS,
-1, 0) = 0x40018000
_llseek(3, 0, 0xbffff580, SEEK_CUR) = -1 ESPIPE (Illegal seek)
write(3, "socket: Operation not permitted\n", 32socket: Operation not permitted
