Couple of things.
1. Make sure sound works on your client to begin with. The handbook
has good instructions if you need them.
2. After you've started esd on the client, make sure it's actually
listening on the correct port. On my client, this is what I see:
host% sockstat -l4
USER COMMAND PID FD PROTO LOCAL ADDRESS FOREIGN ADDRESS
root Xorg 6583 3 tcp4 *:6000 *:*
root Xorg 6583 5 udp4 *:50689 *:*
dpoland esd 642 3 tcp4 10.0.0.1:16001 *:*
3. On the server, you don't actually run esd, just an app with esd
support compiled in.
4. Finally, the fact that you're using KDE is *probably* the issue.
KDE uses arts for sound processing, and IIRC, doesn't play well with
esd. Since I do not run KDE, I cannot advise you further on how to
redirect sound in that environment. However, there are thousands of KDE
users out there and I'm sure google will turn up something.
