Description Tijben 2005-05-15 15:33:24 UTC

Version:            (using KDE KDE 3.2.3)
Installed from:    Slackware Packages
OS:                Linux

When running JuK (don't know about other sound applications, don't use them as much) artsd crashes randomly: 'The application Soundserver (artsd) crashed and caused the signal 11 (SIGSEGV)'. The following backtrace applies *sometimes* (sometimes the crash handler says it's unable to produce a backtrace):

(no debugging symbols found)...Using host libthread_db library "/lib/libthread_db.so.1".

For what it's worth, I'm using an onboard Realtek ALC650/655 Audio AC'97 with alsa.

When artswrapper is suid root, there is no crash window but instead the system instantly freezes, leaving no choice but to do a hardware reset.
