well, here's how to restore the startup chime on a macbook pro. It may work for the imac.
Thanks jerwin. I actually looked into it. The iMac firmware doesn't allow for a bootaudio parameter.
Hey all - I just noticed the classic startup chime is absent from my new 2017 iMac. Could other 2017 iMac owners please confirm that so I know there's nothing wrong?
I am not happy about losing the chime...dual booting with the Option key is now a guessing game. Unless someone can recommend an EFI boot like rEFIt that no longer seems to work. Having to restart my mac 5 times to get a dual boot because I was too early, or too late...can't be good for my mac.
New Macs haven't been chiming through external headphones, speakers or audio interfaces since 2006. Always happens through the internal speakers on Intel Macs.Glad the chime has gone, sods law dictates that one of my kids would have maxxed out the volume before killing the mac previously and the full blast through a monster speaker set up would dislodge a well glued wig....
This thread is about the iMac, not MacBook. Even so, it is pretty common these days to simply keep a MacBook in sleep mode and open the lid to wake it up instead of having to boot it up in a public setting.As I understand it, the chime was removed from the macbook because it's often used in places where discretion is appreciated-- libraries especially.

What about PRAM reset cues?
How to reset NVRAM
Shut down your Mac, then turn it on and immediately hold down these four keys together: Option, Command, P, and R. Keep holding the keys for about 20 seconds, during which your Mac might appear to restart. (If you have a Mac that plays a startup sound when you turn it on, you can release the keys after the second startup sound.)
When your Mac finishes starting up, you might want to open System Preferences and adjust settings that have been reset, such as sound volume, display resolution, startup disk selection, or time zone.
How to use macOS Recovery
Hold down Command-R or one of the other macOS Recovery key combinations on your keyboard immediately after pressing the power button to turn on your Mac, or immediately after your Mac begins to restart. Continue holding until you see the Apple logo or a spinning globe. Startup is complete when you see the utilities window:
