can't load arts soundserver

[ntrhieu]

Hi,
I have a problem with sound in KDE. The arts soundserver just can't load at startup. Other non-KDE application (like gxine, gaim, etc.) works fine, with nice sound. But I can't use any of the KDE application like KsCD or KMixer.

I tried the some command lines and had the following errors:
# artsd "/dev/dsp"
loading extension from '/usr/kde/3.1/lib/libartsmidi.la' failed: libesd.so.0: cannot open shared object file: No such file or directory
MCOP ObjectManager: Could not load extension libartsmidi.la.
MCOP ObjectManager: can't find implementation for Arts::MidiManager.
loading extension from '/usr/kde/3.1/lib/libartsbuilder.la' failed: libesd.so.0: cannot open shared object file: No such file or directory
MCOP ObjectManager: Could not load extension libartsbuilder.la.
MCOP ObjectManager: can't find implementation for Arts::ArtsBuilderLoader.
Segmentation fault

kmix: error while loading shared libraries: libesd.so.0: cannot open shared object file: No such file or directory

I tried to add the path to libesd.so.0, which was /usr/lib/ao/plugins-2, to LD_LIBRARY_PATH, but still had the same errors.
Here is my USE in make.conf:
"X -gtk -gnome alsa qt kde avi mozilla quicktime mpeg arts dvd gif png zlib libg++ xmms kerberos sql java truetype spell ncurses oss xv freetype xfs radeon -rage128 -matrox -3dfx -gamma -i8x0 "

What should I do now? Does anyone have any idea?
