I'm sitting in a library where you are supposed to be super-quiet, and whenever I fire up my machine, I get the fantastic, yet quite *loud* startup sound "inititating startup sequence".
I muted everything (and saved) in SoundMixer, and tried the alternative "alsamixer"/"alsactl store" xterm commands, but it still gives me the sound loud and clear on startup, which grows more and more embarrassing (can you imagine the number of "shhhhs" I got? Hahaha!).
SO, how do I switch it off? (Just temporarily, wouldn't wanna miss it in less sound-sensitive contexts!)
