I've found a way to reproduce this bug, it is caused by suspending. If I try to suspend the system, it will fail and pacmd will go off at 100% CPU. After killing pulseaudio, pacmd is no longer re-spawned.
This issue seems to be connected to suspending in the newest Lucid. ** Attachment added: "Logfile as per https://wiki.ubuntu.com/PulseAudio/Log" http://launchpadlibrarian.net/37925840/pulseverbose.log.gz ** Summary changed: - pacmd running wild 100% CPU + pacmd running wild 100% CPU when trying to suspend -- pacmd running wild 100% CPU when trying to suspend https://bugs.launchpad.net/bugs/507941 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
