That file esists. I was looking in /emul/linux/x86/lib. ;-)

If I write:

LD_PRELOAD=${exec_prefix}/lib/libaoss.so.0.0.0${LD_PRELOAD:+:
$LD_PRELOAD}   exec "$@"
echo "running with LD_PRELOAD=$LD_PRELOAD"

I get:
[sp ~]$ aoss32 vmware
ERROR: ld.so: object '/emul/linux/x86/usr/lib/libaoss.so.0.0.0' from 
LD_PRELOAD cannot be preloaded: ignored.
(five times)

and the echo statement is not executed.
If I write:
  LD_PRELOAD=${exec_prefix}/lib/libaoss.so.0.0.0${LD_PRELOAD:+:
$LD_PRELOAD}  echo "running with LD_PRELOAD=$LD_PRELOAD" && exec "$@"

I get:
[sp ~]$ aoss32 vmware
running with LD_PRELOAD=

?
However: no preloading error message, but sound does not work.
BTW: are you sure sure that one can still set LD_PRELOAD to an 
*absolute* path?

Always as a normal user. I open a "new root shell" in Konsole when I 
wish to be root.

I can hear the sound.

Right. I apologize for my foolishness/laziness. Let me say that I was 
a bit tired yesterday evening ;-)

On Marc 27th, 2005 you wrote in a VMWare Forum:

Are you sure that that has not been reverted in glibc 2.4-r3?
