I have a MacBook Pro 2012 mid 13" (with the newest Yosemite update) and some time ago I noticed, that startup sound was gone. I googled a little bit and saw that resetting PRAM should solve the problem. It did. But after a few days startup sound was gone again. So I reseted PRAM once again, and it fixed the problem. Now the sound is gone again and I'm tired of reseting PRAM, I'm pretty sure that's not how it should be. Does anyone have any idea what's the problem here? Maybe that's a sign that I need to change my RAM? :s

This happens to me all the time, if your computer is muted when it turns off it won't bong when you turn it back on (doesn't apply to restarts). A bit odd but it happens.
