Hi, Thanks for your help. I tryed the patch, but it wouldn't patch on alsa-lib-1.0.15. I also tryed the url, but the projects directory doesn't seam to exist on that ftp server. I forgot to mention in my prier message that the lockup happens with the music player even when I turn speech-dispatcher off.
