I've made an update through yast2 couple of days ago and since then neither opera nor firefox can use the sound server when amarok is running(amarok is using alsa).

Any idea on how to fix it at least for opera? Whenever there is some sound involved on the site opera hangs for a couple of seconds, here is the console output
