It is in a different place in K12LTSP: /etc/profile.d/ltsp-esound.sh

libaudiooss.so is only preloaded if SOUND_DAEMON=nasd is set in
/opt/ltsp/i386/etc/lts.conf. This is the default with K12LTSP 4.x

You can double-check that LD_PRELOAD is set by logging in from a
terminal, opening a shell, and typing:

 	echo $LD_PRELOAD
