Send sound to earphone on boot-up

I spend a lot of time in a library and find it embarrassing when my MacBook Pro plays this loud sound on the speakers on boot-up, even when I have plugged my earphones in. Its also seems my speaker volume settings doesn't affect the volume of the speaker on boot-up. On my Windows PC, I can turn off selected sounds, such as on Windows boot-up.
Is there a way to fix this?

If you make sure to turn your volume off before you turn the computer off, then you wont have to deal with the startup sound.
Or you could download a third party application, like startupsound.prefpane

Hope that helps.

  • Sound output jack has stopped sending sound to remote devices

    The output jack no longer stops the embedded speakers from playing music files. I used it to send sound files to my headphones and stereo system and will be lost if I can't get the jack working again. Somene, please bail me out of this no sound to external devices scenario. Many thanx for checking this request out.

    Hi folks,
    i have an apple IPhone4. I am experiencing certain problem with my iphone4. The problems are as follows a. my ear piece and proximity sensor is not working while making a call. 2. It cannot reproduce sound without earphone but rings normally if gets any call.
    Can any one help me in this regard??

    Try to reset the phone by holding the sleep and home button for about 10sec, until the Apple logo comes back again. You will not lose data by resetting, but it can cure some glitches after installing new software or apps.

    My Macbook Pro 17" 2.44ghz all of a sudden one day decided to not boot up. When the power button is pressed the sleep light in the front on the latch release turns on and there is a small running sound but it never boots up and the screen never lights up. Anyone else have this problem? Any ideas?
    I'd love to repair it but not if it'll cost 500 bucks or more to replace the logicboard.
    I appreciate any help

    Lao Bo,
    yes, you can locate and copy a file from your HD to a USB key using UNIX commands. If you know the exact name of the file which you’re trying to locate, try this:
    find / -iname filename -print
    This command will search your entire internal disk for the particular filename. If you know that it’s within a particular user account, then you can save search time with this variation:
    find /Users/username -iname filename -print
    Either variation of this command will print all files found which have the given filename. Presuming that you’re able to identify the correct file, you can copy it to a USB key using the command
    cp -p filename_returned_by_find /Volumes/USB_volume
    If you’re not sure which volume name your USB key has, this command will show you what the possibilities are:
    ls /Volumes
    Please let me know if you have any trouble with these commands.

  • Send sound only from iPad to Mac mini via Airplay

    I just downloaded AirServer on my Mac mini thinking it would be great to send sound from my iPad to the Mac mini via Airplay.
    While the sound works fine, I still find that it would nice if only the sound would be sent to the Mac and the display remains on the iPad.
    My Mac mini is my music system (with no monitor), so I tought I could listen to videos from Youtube on my music system, but then the display needs to remain on the iPad.
    Is there any way I can achieve this?
    Thanks.
    Paul

    I found the setting in AirServer allowing me to stream Audio only. Now I just have to wait for the update to fix the audio delay issue I have.

    Have you checked System Preferences -> Sound to see the Output when nothing is plugged in the headphone jack? Also, check if the headphone jack shows a faint read-light, which is the optical laser.

  • "Mail send" sounds upon wakeup

    Sometimes when I wake my Mac up in the morning, I hear several "Mail send" sounds in a row. This morning it was 15. When I go to Mail I don't see any activity, and there's nothing in my "Sent Mail" box to show for all those sounds. What's the deal? Is this a known issue? Have I been hacked?

    SusPup--
    Have you set up automatic notifications in iCal?  I have that set to send me emails in the morning.

  • 10.6.7 Update No sound   5 mins to boot!

    Updated from 10.6.6 to 10.6.7 last week and lost sound.
    There's now no input or output options in the sound control panel and the Mute checkbox is greyed out but 'Mute' in checked. 
    It's as if the OS sees no sound drivers or no sound hardware now
    Can anyone shed any light on this?
    In addition my machine now takes a good 5 mins to boot, seems to run fine once it's underway  - apart from no sound.
    This initial boot up screen looks OK, but then it sits on a blue screen for 5 mins - then boots
    Mac Tower

    8GB RAM

    Firstly to try to cure the slow startup go to System Preferences>Startup Disk. Click on 'Macintosh OS X, 10.6.7 on Macintosh HD' and restart. Hopefully it'll start up at normal speed.
    To try and fix the sound issue you could try downloading the combo updater (if you haven't already): Mac OS X v10.6.7 Update Combo
    and reapply the update.
    Often re-applying the update using the combo fixes unexplained problems.
    If this helps you may need to repeat step one again as it seems that sometimes the Mac seems to struggle to find a startup disk, often after new installs/updates.
    Before and after doing the update I'd also suggest repairing disk permissions: Utilities>Disk Utility, select Macintosh HD, click 'repair permissions'.

  • Dock not sending sound, Dock not sending sound anymore in iPhone 4

    My iPhone isnt sending sound through The Dock, but it charges, what should i do?? What could it be?

    Unless you have experience dealing with micro electronics, and the proper tools, and prior experience with iPhones, the odds are good that you damaged a connection or didn't make a proper connection. I have a friend, that owns a business, that specializes in fixing iPhones. Over half is business is fixing iPhones that owners attempted to fix themselves.
    Go here, they have complete instructions, see if you can determine where the problem rests:

  • How can I send sound from microphone to Bluetooth speakers?

    How can I send sound from microphone to Bluetooth speakers? They work from the music app but not from an internal or external microphone.  Is this a setup issue or is there a work around?

    I don't know of any way to do that.

  • Pavillion dv6 shows sends sound to headphones when none connected

    All my video chat programs work with sound coming out of my notebook...then along comes facebook video chat and my notebook decides I have headphones attached and refuses to send sound out of the speakers....help!!!! It worked for a week or so! All other programs....skype msn etc. still work.

    I have the exact same problem with desktop HP Pavilion HPE (H8-1022). Despite the Beats Audio and the Windows control panel having the external speakers set as the default devices for playback, when using FB video chat all the sound gets routed to the headphone jack. If you find a solution for this, please post !
