IMac 21.5 sound output flaw

I have a small flaw with my 21.5 iMac's sound output. When I plug my Philips headphone into my iMac's build-in sound output hole, it takes about 2 seconds to transfer the sound from the build-in speakers to my headphone. Also, when I take my headphone out, it takes 2 seconds to come through the build-in speakers. When I did set up my iMac, I received static electricity by touching the bottom of it. This flaw does bother me. Did the static electricity caused it? Is this normal or a flaw? How can it fix it?

The delay isn't a flaw, it's the time it takes for the switch inside the jack socket to recognise something has been inserted, mute the internal iMac speakers and redirect the audio to the socket.

  • The choice of headphone jack is not showing up under the system preferences - sound output options.  Therefor, my speakers suddenly do not work with my iMac

    On my Intel based iMac, OS 10.6.8, my speakers suddenly were not transmitting sound. When I checked the System Preferences, Sound output, the headphone option was no longer available.  This has always worked in the past - what is up?
    Anyone have any suggestions???

    Applications > Utilities > AudioMIDI Setup.app

    Side Bar
    Click the Built-in Output.
    Under Mute any of the boxes checked? If so uncheck it.
    Plug in the headphone and check whether in the output  headphone shows up in the same panel.
    If so, you can adjust the volume there.

  • Selecting sound output on new alu iMac

    I realise there have been quite a few posts about similar topics in Apple Discussions, but I would be really grateful if somebody could answer this one. I am using Tiger 10.4.11 (i'm waiting for software updates for Leopard to be released before installing it).
    My question is, why haven't I got the option to switch sound to my iMac's internal speakers while still having my headphones plugged in?
    When I go to System Preferences > Sound, the only sound output options I have are 'Headphones', and the Bluetooth headset that I use for iChat. It seems logical to me that I should have the choice to switch between internal speakers and headphones.
    When I unplug the headphones, the internal speakers show up, any ideas? Could it be something to do with the Audio MIDI setup options?
    Thank you in advance for your help.

    I have a newer alu iMac, 24" and I have SoundSticks connected (external speakers). My options for Sound in SysPrefs are the SoundSticks or internal speakers. I have the option to select either one, even while the external speakers are in use.
    I would think that you should have similar options, but maybe the Headphone option cancels the internal speakers similarly to how cell phones work when an earpiece device is connected. You don't hear sounds coming from the phone until you disconnect the earpiece.

  • System preferences in iMac for sound output shows only headphones. How do I change this to get sound through computer? Thanks.

    In sound System preferences on iMac  headphones is only option for sound output. How do I change this to get sound output through computer, as in a video etc. Thanks.

    There is a switch in the jack that may be stuck. Try plugging and unplugging a headset plug into the socket a few times.
    You might try dipping the headset plug into some pure alcohol, wiping it nearly dry, and repeating the process to clean/clear the socket.

  • Can I put ALL the sound output from my iMac through Airport?

    Just got Airport Express, and managed to install it very quickly on my existing Belkin network. Just don't forget the $ before your WEP key.
    Does anyone know if its possible to put ALL the sound output from my iMac through to Airport, rather than just iTunes? So internet radio, streaming videos etc?

    Thanks matey - that's just what I was after.
    Not sure if that will also let me put my iMac's system sounds through my HiFi - probably not - but then who in their right mind could possibly want to...?
    (Be nice if you could though)

  • After updating to 12.1.2.27, songs play, but without any sound output to internal iMac speakers

    So i updated to 12.1.2.27 and songs 'play', but without any sound output. Checked my audio settings and had it at Internal speakers. Checked the speakers (they work, at least for YouTube vids), restarted machine, etc and no audio output from iTunes. Any suggestions? Am I missing something?
    Thanks in advance

    Try unchecking Sound Enhancer and Sound Check in your Preferences under Playback
    Sound check may have reduced everything to a low output level inadvertently.

  • IMac sound output changes

    As I'm trying to watch tv shows I've bought from iTunes the sounds keep turning on and off.
    I opened the sound preferences and found the output was switched to digital out- I cant even remember the last time I put headphones in!
    Then, as I put my show on, right before my eyes the sound output changed from digital out to internal speakers (at which point I could hear my show once again) before it just as quickly changed to digital out without me doing anything at all!
    How can I stop this?

    I don't think there is a real fix to the problem, there was a thread about this a while back and no one came up with anything, but to just get it to go back to built-in output, try plugging an 1/8th inch cable into the audio out jack, then either a) jiggle the plug in the jack (seems to have worked for other people) or b) adjust the computer volume (worked for me - I used the keyboard buttons rather than the sound preferences to do it, not sure if it makes a difference), then unplug it, and your sound output SHOULD change back to your internal speakers. Hopefully. Try both methods a couple of times if it doesn't.

  • Can not change sound output. Help Please

    Well, i've been digging all the forums lately in web. my problem is, i can't change my 'system' sound output to my sound card which is Native Instruments Audio8 Dj.
    Let me explain my problem decently. I do the usual procedure, system preferences > sound > n then select the output. but nothing happens. it is always set on internal speakers or headphone or whatever plugged in to the *Built-in Output*. I try switching from audio-midi setup n that doesn't work as well. The system perfectly recognizes the sound card, i can get output from sound card with applications which have their own output settings. But i cant change the system output. I have the latest version of soundflower loaded(this might be causing the problem who knows), i used many soundcards before(or maybe even ex-drivers?) n they used to work until i updated to snow leopard. I also tried trashing the files in macintosh hd > library > preferences > audio >>
    and those files *did not regenerate* after restart(like 10 times), so i had to copy them from my imac.(hehe). i tried resetting pram or nvram.(didn't do any good too)And also i tried trashing soundpref.plist which didn't do me any good neither. Now i need that sound card to give me my system output. I don't need drivers of any other ex-sound cards or whatever. My drivers are up to date. And im pretty sure this ain't an hardware fail.
    So, any ideas? Thx.

    I am having the exact same problem. I have spoken with Apple Care and they are having my case reviewed by "Engineers," apparently. Its very frustrating as I cannot listen to iTunes or any of my video games through my really nice monitor speakers. FYI, I had this problem without installing Sound Flower, since then I have installed it in the hopes that having something different to select it might work but no changes. If I hear any good news from Apple I will be back to let you know. This seems to be a very rare problem as I have only found one other post about this issue.

  • Sound output: keeps changing from internal speakers to Apple TV

    My iMac keeps changing the soudn output from internal speakers to Apple TV. Why. This makes it a pain. Eveytime I use the iMAc, I have to go into preferences>sound>output and switch to internal speakers. Any ideas how to stop this form happeneing?

    If you use LogMeIn, it is their sound driver.  I'm having identical problem and it started after using LogMeIn.

  • How to change sound output?

    Howdy
    I recently bought a high-end toslink cable which I connected from the optical/digital out from my iMac to my receiver. The sound quality is excellent, however I noticed that all sounds now gets passed to my Hifi system all the time. The only way (I could find) to route sound to the internal speakers is by physically unplug the cable. This is really not workable in the long run as it wears down the plug and, not to mention, my patience...
    So, anyone know any way to switch output to internal speakers w/o having to unplug the cable? Or is there another approach (I'm thinking Airport Express)?
    /Cheers

    Unfortunately, you cannot select +Internal speakers+ in System Preferences Sound pane Output tab, if you have something plugged into the audio output port.
    If you got an AirPort Express, its AirTunes feature would certainly work for iTunes output. However, I believe AirTunes would only play the output of iTunes. So it would work great as long as you were only playing songs and videos using iTunes, because all other sounds will come from your computer speakers. No need to change any setting manually, after you are done listening over the stereo system. However, it would not work so great, if you wanted the audio output of some other programs to be played from the stereo system; but there seems to be a third-party solution for that issue
    http://www.rogueamoeba.com/airfoil/mac/
    If you have separate powered computer speakers that connect using a standard mini-jack, one alternative is to get a USB (or possibly FireWire) sound output device (if you want to be able to change the sound output setting manually). The least expensive one may be the Griffin iMic.
    http://www.griffintechnology.com/products/imic/
    It provides a second sound output port over USB, so it should show up as a separate choice in System Preferences Sound pane Output tab. Therefore, you should be able to use the Sound preference pane to manually switch the sound output from you stereo system to the computer speakers connected over the USB iMic.

  • 2 Apple TV's and no sound output when using AirPlay/mirroring?

    Hi,
    Bought my first apple tv and when air mirroring was able to go to my system preferences and choose sound output for it and it worked beautifully when I wanted to play a movie on my computer and send it to the TV.  Bought a second apple tv for the bedroom, both are connected over wifi.  Using Mountain Lion on my iMac.  Now it won't play any sound on either and will not let me choose which apple tv in system preferences - sound.  Any help would be appreciated
    Sue
    I have tried turning Apple TV on first, then choosing sound output before turning on air mirroring.  Problem is it won't let me choose, stays on internal speakers.
    This fix won't work for me.

    Might I recommend the following sample code instead?

  • System Sound Output Level Reset After Reboot ?

    Whenever my iMac Core Duo is rebooted, system sound output level always get reset to value 0.56 (-24dB) as shown in utility "/Applications/Utilities/Audio Midi Setup". I have to increase the system sound output level to desired value of 0.75(-12.75dB) to match with built-in amplifier of Altec Lansing FX6021 speaker system. The desired setting lasts until next reboot. Is there any way I can fix the system sound output level at desired level between reboots ? Why I have to be involved in such constant struggle with the iMac for such simple audio configuration ?
    Audio Hijack Pro 2.6.7 wihtout Soundflower 1.1 virtual audio device has been installed. Audio hijack function of this utility has not been used at all. Thank you for any pointer.

    Thanks for the confirmation that my iMac is not an isolated case. In case you are not willing to use Audio Hijack Pro, just use Automator to create an Automator script to set system volume (In Automator's Library plane: Applications>System>Set System Volume) and save it as application. Set this application as Login Items for your account through following menu path:
    System Preferences>Accounts>Login Items. Whenever you login with this account, the script will be invoked automatically by Mac OS X and sound levels for output, input and alert will be set to user preferred levels. For older versions of Mac OS X (10.3.9 and earlier) without Automator, same effect can be achieved with Apple Script, use Apple Script Editor instead of Automator to create Apple Script and set it as Login Items. This workaround has been working consistently on my iMac Intel Core Duo.

  • Sound output device

    Hello,
    Recently I have been experiencing problems with my sound in my iMac with OS X 10.6.2
    In my sound output device list, I have the following:
    - Headphones (Should be selected)
    - Soundflower (2ch)
    - Soundflower (12ch)
    To hear sound from my iMac speaker or headphone, the Headphone option should be selected. However, everytime I reboot the OS, it go to the soundflower and I have to manually go to system preferences and select the Headphones. I don't even know what the Soundflower is and why it is there. How do I make the "Headphones" as the default selection?
    This has been an issue for the past month or so.

    Soundflower is an audio routing program that emulates an output. It comes in very handy for people like me who use studio monitors through an audio interface as Apple doesn't allow you to adjust the volume on such setups with a keyboard (no idea why, since it works PERFECTLY under Windows 7 on Bootcamp, but I digress). I'm not sure how you installed it by accident, but you can delete it if you don't need it.
    To fix your issue you need to delete the audio preferences file (I forget where it is, hopefully someone can help me out), then select the headphone output again and it should remember your setting.

  • Sound Output Through miniHDMI port

    I am trying to link my 13 inch MacBook Pro to my tv so I can watch videos I have on my computer on my TV. I have the mini HDMI cable converter hooked up. I am getting video from the computer to the TV but no sound. I tried a headphone to RCA converter to get sound to the TV and this works if I have the TV source set to AV. However this only sends sound to the TV and not video. And the way the TV source works I cannot select HDMI video input and av sound input. Is there a way I can force sound output through the miniHDMI cable so I can get sound and video through one cable? I would greatly appreciate any information and help anyone can provide.
