Jan 22, 2015 10:03 PM in response to gotham1by K Shaffer,Usually, if you press the Mute button (do not hold it at any time) that will set
audio to Mute on startup. On some models, it was possible for a headphone
plug to be in the audio-out jack to effectively turn off audio to built-in speaker.
Since most who reply to topics here, are not Apple employees and do not at
any time represent Apple, Inc. a better idea would be to send Feedback to
an appropriate department of the Company via their Feedback site links, as
provided on the Apple web site in various locations. Following links are from
the Apple Contact Us page: http://www.apple.com/contact/
"Tell us how we’re doing. Select the appropriate feedback option "
(we read everything, but can’t always respond):
Some of the command-line methods successes varied over time and between
different OS X system build versions. There may be some successes in how
to attempt to Mute system audio, with the AppleScript angle; that too will vary
depending on where the command was said to begin implementation... If it
was in the wrong location in the system or written incorrectly, it may not work
if the computer was not awake to run it. (Poorly written commands need repair.)
I'd try a third party tool such as Cocktail or OnyX to see if they offer a simple
tool in their tweaks that may perform this task. There is a build of either one
of these tools for each OS X. There are no guarantees, so if you suggest to
Apple Feedback your concern & question, someone will likely read through it
but you may not see a reply. And If some aspect of the OS X function appears
to have a Bug, you may seek to read about how to File a Bug report instead.
Sorry that you find issue with those who are here, as part of a user-to-user
product owner network of volunteers, who do not represent Apple and cannot
reply about any issue in authority on behalf of Apple, Inc. Almost nobody here
has an official capacity in the ASC discussions, other than Community Hosts.
So these are my recommendations for you to consider. Or not...
Good luck & happy computing!

Mar 4, 2015 8:08 PM in response to imicanadaby shazam456,You can turn off the startup sound — at least on some Macs — by turning down the volume "slider" control located in the upper left of the OS X display ***AND*** doing the same in iTunes before you shut your computer down. When you start the computer again, it should be silent. The volume must be turned down both on the desktop ***AND*** in iTunes or the sound will persist.
This definitely works with a 3.2 GHz Intel Core i3 iMac running OS 10.6.8 and will probably work with other models as well. Nothing else I tried was successful, and I finally figured this out by accident. The startup chime can be extremely annoying, particularly when you want to work on a Mac after everyone in the house has gone to sleep or in environments where quiet is essential.
I hope this will be helpful, even though my reply is coming long after the initial post. :-) -
Apr 6, 2015 7:33 AM in response to Hippomormorby giessen,On my MacBook Pro (Retina, Mid 2012) running 10.9 Mavericks, the solution
sudo nvram SystemAudioVolume="%80"didn't work for longer than a few days.
The solution first mentioned by Hippomormor, perhaps originally proposed by Macworld Hints in 2003, worked on 10.9 but became problematic after I upgraded to 10.10 Yosemite. Although turning the sound off before shutdown still worked, turning it back on after boot-up often failed and had to be done manually.
To solve this, I kept the part that mutes at shutdown:
sudo nano /Library/Scripts/mute-on.shand pasting
#!/bin/bash
osascript -e 'set volume with output muted'and saving, and then
sudo chmod u+x /Library/Scripts/mute-on.sh
sudo defaults write com.apple.loginwindow LogoutHook /Library/Scripts/mute-on.shall as described by Hippomormor. But I had to make changes in the part that puts the volume back on at boot:
sudo nano /Library/Scripts/mute-off.shwith an extra line in the script to make it wait until the Applescript system is ready:
#!/bin/bash
sleep 10;
osascript -e 'set volume without output muted'and after saving and closing, I created a new file /Library/LaunchDaemons/com.giessen.soundon.plist with these contents:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>Label</key>
<string>com.giessen.soundon</string>
<key>RunAtLoad</key>
<true/>
<key>Program</key>
<string>/Library/Scripts/mute-off.sh</string>
</dict>
</plist>Now it all works again on 10.10. From the reactions above, it seems to me that mileage may vary in big and unexpected ways. That is strange, since we're all using the same operating systems.

Thanks,
I have checked previous discussions. I think it ought to be user's choice to use it or not.
But it isn't (unless by a 3rd party utility) so, bearing that in mind what would you like to do?

Jun 26, 2015 6:20 AM in response to Hippomormorby Jinius Evil,Thanks for this trick! I've modified the line from
osascript -e ‘set volume with output muted’
to
osascript -e ‘set volume 0.1’
I think it is just good to hear the start-up chime... someone once wrote that it is a part of a start-up troubleshooting feature, so silencing it might not be the best idea. So making it softer would and could be a better solution. I think one can go even lower than 0.1... so feel free to experiment.

Dec 27, 2015 1:18 AM in response to kuhakby Captain_Dangerous,The nvram solution works on Yosemite (10.10.5) too I'm glad to say. I'd reset nvram using Cmd-Opt-P-R on startup trying to rectify a failure during update to El Cap. The original software I'd used to mute the chime- chime? more like a discordant noise! - didn't work after the PPC emulation code was removed from OS X. All is well now as peace has been restored and I don't have to remember to hold down any keys during startup or shutdown. Thanks kuhak.

Jan 2, 2016 9:50 AM in response to wariovonflutenhausenby Bmorgan5,For iMac users who don't want to hear the startup chime I have found a simple and permanent solution: mute the internal speaker and monitor sound through the headphone port or an audio interface (plugged into in the thunderbolt or USB port).
First, just a little background: Unlike many laptops, plugging something into the headphone (audio output) port of my iMac does not stop the chime, because the internal speakers continue to play the chime. However, you can control the sound of the internal speakers separately from the headphone port. If you mute the internal speaker it stops the chime.
Like many people, I always listen to the audio of my mac either through a sound system or headphones plugged into the headphone port (or else through an audio interface plugged into the thunderbolt port). So muting the internal speaker doesn’t affect me; I can still hear audio. Also, I don’t have to constantly mute and unmute anything, or put any code into the system.
How to do this: When you have nothing plugged into the headphone port the system preferences for “Sound” let you mute the internal speakers. Be sure nothing is plugged into your headphone port. When you have something plugged into the headphone port the system preferences will allow you to change the settings for the headphone port only, and not the internal speakers. (By the way this seems like a confusing set up. Why not have these in the same menu at the same time?)
