No start-up chime...

[LunarianCrystal]

My macbook pro no longer has a the apple trademark chime during bootup. Not only that but the sound balance seems to be off on my computer. This just randomly started happening. I tried messing with the PRAM to fix this but the PRAM didn't work... I held command/option/P/R and the computer just kept restarting OVER and OVER again.... with no chime. I'm pretty sure the sound on my computer is messed up and not sure why. Anyone got any ideas? Why does my computer keep booting/restarting with no chime as I hold option/command/P/R..? Please help >_<

Just to rule it out, your volume isn't muted right? You won't get the startup chime if it is.
