Hello everybody,
I've just installed Arch Linux, along with X, KDE, and the like. Now, when I boot into KDE, I get this error message saying "Sound server fatal error: cpu overload, aborting".
The error message appears in an artsmessage window.
My computer becomes very slow before I get this error as artsd uses 99% of cpu before it crashes. I found this out using the `top` command.
I have alsa and all of it's modules compiled. The alsa module is also inserted into DAEMONS array.
So.. what does one do in this situation? Thanks.

Have you done a 'alsaconfig' to make sure your card is set up right?

I just tried that. The utility tells me everything is good.
So I decide to try something new. I log in as root and start KDE. Artsd doesn't crash anymore, and it only eats up half of my CPU.

It's another artsmessage window, but this one says:
" Sound server informational message:
Error while initializing the sound driver:
device: default can't be opened for playback (Device or resource busy)
The sound server will continue, using the null output device."
So, i'm stumped. I was going to get rid of the arch installation of alsa, and reinstall from the files i find at the alsa website, but I can't remove alsa using Pacman because other programs need it.
Any advice is greatly appreciated. Aside from this minor wrinkle, i'm thoroughly impressed with Arch Linux. Having used Gentoo before this, it's embodies everything I liked about Gentoo without any of the bloody compiling. Good show.

Arts uses realtime priority as root, hence the better performance. There should be an option so you can run arts in realtime as user (setuid=root?). If you don't mind building your own kernel, try compiling the sound drivers as modules. If arts is still giving you trouble, disable it and use an alternative sound server.
I have nothing to say, and I am saying it.
