I tried this solution, but it didn't fix the problem: during startup, I get just a short sound file that gets played. For some reason, a few days later, the startup sound did play, but it kept breaking up. Also, other system sounds break up occasionally, or perhaps sound "static-y." I also get errors when running k3b - I get a pop-up that says there is a problem with sound system and in the same box claims that there are no problems with the sound system.
Additionally, I have soho 5.8 on a second machine. The same problem is occuring there, too.
Any help is appreciated. Thanks.
