I'm not too familiar with strace. All I changed was /etc/ld.so.preload to
include /usr/lib/libaudiooss.so.1. Same result.

node1-2:~# grep open 2logfile
open("/usr/lib/libaudiooss.so.1", O_RDONLY) = 3
/* all libraries open with result 3 */
open("/dev/dsp", O_RDONLY|O_LARGEFILE)  = -1 ENOENT (No such file or
directory)
write(2, "Can\'t open input file `/dev/dsp\'"..., 59) = 59

node1-2:~# grep open soxlog
open("/usr/lib/libaudiooss.so.1", O_RDONLY) = 3
/* all libraries open with result 3 */
open("/root/sounds/sounds/fanfare.wav", O_RDONLY|O_LARGEFILE) = 3
open("/dev/dsp", O_WRONLY|O_CREAT|O_TRUNC|O_LARGEFILE, 0666) = 4
