Karmic Koala (Ubuntu 9.10) has come out now, and I’m still getting 70 hits a week on my original article concerning PulseAudio. The situation has changed radically, and so that people will get correct information concerning it, I felt it necessary to revise my previous findings.
PulseAudio can no longer be killed off in favor of Alsa. Karmic Koala has so tied up and dumbed down the situation that killing off PulseAudio will kill off ALL sound. Not only that, but there is no way to cause the system sounds (window open/close, button press, etc) to work right. An additional factor is that you are apt to have a heart attack when changing from one user to another due to the HIGH volume level of the alert sound for the new login screen. The only way I’ve found to fix this is to kill off ALL system sounds.
