sound error in kde 3.1 / slackware 9


Whan starting kde 3.1 I receive the following message:

Sound server informational message:
Error while initializing the sound driver:

The sound server will continue, using the null output device.

Here is my setup:

$ ls -l dsp* mix* audio*

great old world of kde
(ever heard someone say kde sucks)
kde uses a deamon called arts
which is initialized when kde starts up(kderc)
so you have 3 choices
1.remove arts from the scripts
2.kill arts
ps -aux|grep arts
now get the pid of arts
kill -s 9 <pid of arts>
and use oss
3.don't use kde
use gnome/blackbox/icewm

what happens if you disable arts (for now) and once inside KDE, if you try and use a cd player or xmms or something else like that... does xmms complain about accessing dsp or does it have no problem playing mp3?

You know... I've been running into a similiar problem... last night I installed 2.5.67 kernel which comes with its own emu10k1 driver for my SB Audigy. (I tried to download the driver from sourceforge but it wouldn't compile against the new kernel). The emu10k1 loads just fine and xmms can play audio with the OSS plugin, but if I start ESD then ESD (plays three beeps at startup) gets caught in a loop and just keeps repeating its startup... seems to me that the driver (emu10k1) has some issues... perhaps a similiar situation is occurring with your sound server?
