Sound problems keep crashing my programs


Hi all... long time lurker, first time poster. I just upgraded from SuSE 10.0 to 10.1, and am having massive problems. It seems that any time a program tries to generate a sound, it crashes. On startup (and after some programs - most progs that crash at this point just disappear without a KNotify window) I get the following message, and just don't know what to do about it. Prior to upgrading, my audio was acting weird anyway. Whenever one program was using the soundcard, the rest of the programs wouldn't have access to it at all, but nothing crashed before.

Help! I can't function like this!

Code:
System configuration startup check disabled.

Like Windows, Linux distributions such as SUSE can not be upgraded to the latest version. You have to backup and do a complete full install. Gentoo does not have this problem because it has tools to check the consistences of all programs and libraries after a full system and world updates are done.

On-board sound cards and some PCI cards needs software mixers because these cards do not have hardware mixing. Windows users can get a way with this because the manufacture includes on the fly software mixing that is transparent to the user. New Linux users have problems understanding it. To correct it, you can use esound, arts, SDL, or ALSA's library dmix. Each one has its problems and their complexity is the same. What ever you use is up to you. IMHO, esound is probably the best because you do not have to change your configuration for each program you use. arts has a lot of problems with many programs. SDL is like DirectX, but the program rarely has support for this. ALSA's library dmix could be used by it is not transparent to every program, so the configuration have to be changed for every program.
