MacIntel: Startup chime stuck with internal speakers?

MacPro, Intel chips, 10.4.10, self-powered speakers plugged at the back.
The boot chime ALWAYS comes from internal speakers, no matter what settings are used in Sound preferences panel. (The chime can be muted, but' that's it)
Previous Macs (at least G4s) with the exact same OS version allowed getting a beautiful, deep and soothing sound at startup time, from externals. Why would this feature have disappeared?
People at the store and at Apple that I've talked to only said :it's normal".
Anyone can help me with this? I find it strange that this would be "normal". Even Windows can have its boot chime presented through externals.
Thanks!

Yes, it is normal. You might want to try using the front headphone port instead. I believe it'll come out via that port though I'm not entirely sure.

Problem with internal speakers of MacBook Pro

Hi,
I wanted to know if anyone have experienced a problem with internal speakers of Mac Book Pro. In my MackBook the Internal speaker volume goes down automatically. I checked the System Preferences>Sound>Output , from there I check that it is in the middle ( Balance) However, the problem is still the exists. Just for testing I played an audio file and I moved the bar toward the right speaker it is the same and when I move toward the left speaker the whole sound goes off . Looks like one speaker stops working completely. Then I checked the Utilities > Audio MIDI Setup > Configure Speakers from there I checked both left and right speakers and the channel frequency is fine. Still same issue. I have no idea what is going on , I really need your suggestions to get this fixed.
Thanks in advance.

10.4.10 Audio Popping Issues: Information Check with Internal Speakers

For people with internal speakers, or those without subwoofers: Please read all the way to the bottom to find a test that will determine whether you are also having audio problems, even if you can't hear pops.
We've had a lot of discussion about audio popping due to 10.4.10, and the evidence indicates that the audio circuitry is going to sleep to conserve power, even on AC-only computers like the iMac, Mac Mini, and (at least one) Mac Pro. Some people claim to not have this problem, but I'm wondering if they just aren't noticing it.
Having external speakers with a subwoofer, set to high amplification, are key to obvious detection of the problem. Let the sound subsystem go idle for 30+ seconds (wait a minute with no audio, just to be safe), turn up your external speakers really loud, and cause the computer to make a sound. You should hear a burst before the sound plays. If you repeat the sound, you won't hear the burst. This is the sound of the audio circuitry powering on, and the speakers are amplifying it.
About 30 seconds after the sound finishes playing, if you leave the volume of your speakers turned way up, you should hear a "pop" as the circuitry is powered off. Then, playing another sound will recreate the burst.
I haven't been able to hear these sounds with internal speakers, either on the Mini or iMac. But the problem still exists, and it is detectable... if you know what you are looking for.
The burst of the audio circuitry turning on also causes a delay in the audio. The delay is a noticeable fraction of a second, an it can easily be detected if you have a repeatable source of sound. I like Terminal.app, because I use that application all day, every day. Here is how you can check to see if you are also subject to the audio problems:
1. Start Terminal.app (in the /Applications/Utilities directory).
2. Wait one minute for the audio circuitry to shut down.
3. Without typing anything else, very quickly strike and release the Backspace key.
4. If you pressed the key all the way, the program should have caused a beep. However, if the audio circuitry goes to sleep, the beep should occur after you have moved your hand off the key. This is because the circuitry takes time to power itself on before playing the sound.
5. Now, quickly strike the Backspace key again. You should notice that the sound is produced immediately as you hit the key, without the delay you just witnessed.
6. Strike the Backspace key repeatedly, to confirm that there is no audio delay. Do this about once every second or two. If you press the key too rapidly, not all of the presses will produce sounds... this behavior is not related to the issue we are testing.
7. Wait another minute for the audio circuitry to shut down, and strike the Backspace key once more. You should again observe a delay between your strike and the sound production.
If you witness delays like this, your audio circuitry is also going to sleep, and you are having the same audio problems as the rest of us. However, either because you are using internal speakers, or because your external speakers don't have the appropriate response, you aren't hearing the same bursts and pops as the rest of us.
Please try this test, and report here. I want to build a list of people who previously couldn't hear the sounds, but still have the delay. This might give us a better picture of the scope of the problem.

Re: 10.4.10 Audio Popping Issues: Information Check with Internal Speakers
Your analysis of what is happening is right on.
The problem on my Intel Mac mini with external Klipsch speakers (two mid-range/high and a subwoofer) is REAL obvious as the system emits a hum like a Spinal Tap amplifier turned up to #11 when 10.4.10 powers down the audio circuitry
Then, if I play a song in iTunes, it first pops and the hum disappears right before playing.
Quite annoying.
Here's what I sent to Apple tech support:
Guys/Gals (OS X Engineers):
Concerning the Snap, Crackle Pop Audio problem in the 10.4.10 update:
Please. Just do the right thing and fix the audio.
There is no need to power cycle the audio subsystem to save .0005 amps on your laptops.
And then to make your Mac mini/iMac/other desktop users have to put up with it when using AC power is ridiculous.
Put the audio subsystem back like it was in 10.4.9 and let the laptop battery freaks looking for mini-amp savings get a "work-a-round".

Does your startup chime ignore your external speakers??

I was just wondering if everyone or anyone else's iMacs did this. The startup chime is played through the internal speakers instead of my external speakers.

Hello Alias7
Yes McKappa is correct the MIDI audio setup switches to external after startup and a system wakeup. To lower startup chime volume unplug your external speakers, turn down or mute the volume for the internals then reconnect your externals.

Sound heard through headphones, but not with internal speakers

Recently, my computer stopped producing sound from the speakers. However, I plug in headphones and everything can be heard. I've already checked Sound in System Preferences. Nothing is muted and all sliders are in the correct position. In the Output Pane, my only option for the output source is headphones, no internal speakers. What happened? What should I do?

I recently got the same problem. Its not that bad but confused me at first. If that is the worst problem you get with your computer consider yourself lucky. You could bring it by an apple store genius and see what they say but its most likely a switch problem like tteuer said. If my memory serves me right that switch is connected to the logic board, if you have it still under warranty, great, if not, you might as well get another laptop if it really bothers you.
Tip: I have made it work by either slowly removing the headphone from the jack or rotating it. If that did not work the first time I repeated it.

No sound with internal speakers

My HP dv1660se P/N et732ua laptop does not have internal speakers working? Head set works but not with DVDs, no sound at all. I just installed Windows 7 32 bit.

Hi Kubotaboyz,
Welcome to Lenovo Community Forums!
The Lenovo K450e does not come with an internal speakers.
All Lenovo Tower PC does not have an internal Speaker and you must connect one either through the back Audio port or at the front on some units.
You can check this K4 Model series Maintenance Manual to verify that the unit does not include speakers internally.
Hope this helps

Having problems with internal speakers?

Hello,
          I've recently encountered a problem with my speakers. There is also a red light coming out of the audio jack. I found out that many other people are having the same problems with newer Mac versions. I looked at many different discussions and some are wrong and some are right. Here is a great idea for for making this work: 1) You can use a toothpick. From what I've read, it may work, but be very careful of what you're doing. 2) I've used this idea it works very well. Find a headphone or audio jack cord and plug it in the audio jack many times. What I did was plug it and unplug it very fast. What you're trying to do is confuse the computer for a bit then make it realize that there is nothing in the audio jack. This should work. If it doesn't (for whatever reason) do not use the extra money to get it fixed. If this isn't enough help look at some other discussions, it's how I solve my origional problem with my speakers.
                                                                                                                                                          Hope you find this helpful,
                                                                                                                                                                                                     Adam B.

No, its too expensive for HP to plate the zif connectors with something that doesn't corrode....rolleyes.

I HAVE JUST BOUGHT a MacBook air. The earphone output doesn't work. I read somewhere that you have to make a choice with internal speakers. How?

I have just bought my first Mac a MacBook Air 11 ". Thwe external output doesn't work . Do I have to make a choice between internal and external speakers? If so, How?

Go to System Preferences -> Sound -> Output.

No audio with Internal Speakers Mac Book Pro 17inch

i have reinstalled os from OSX DVD 10.7.0
after that i can hear the audio only from earphones

Go ahead and complete the Software Updates to 10.7.5... that may or may not solve your problem. If it doesn't then your audio output port may be 'stuck' in digital mode. There's a tiny switch inside that can be 'reset', usually, by unplugging and replugging headphones multiple times (fast) or by using a slightly dulled toothpick.
You can usually (but not always) tell whether or not you're stuck in digital mode by looking to see if there is a red light on in the port.

Startup Chimes with audio cable connected?

My Mini has started to sound it's healthy startup chime even when there is an audio cable connected to the audio/headphone output. The output works fine and sends audio to the speakers, but how can I mute the chime at startup?
Previously it always muted that sound with a cable connected and I believe it started chiming when I updated to 10.5.4.
TIA.

The mini generates the startup chime via the internal speakers regardless of whether external speakers are connected or not - the necessary support for the hardware audio port isn't loaded until after the power-on self test (which is what generates the chime) so in common with the iMac range, the chime comes from the internal speakers.
The only way to mute the chime at startup is to set the Sound preference pane to Mute (check the 'Mute' box in the Sound Effects tab). There are also some utilities such as Startup Sound (http://www5e.biglobe.ne.jp/~arcana/index.en.html) which variously succeed in muting the chime, though these tend to get broken with MacOS updates.

My startup chime not muted anymore.

I do not want to remove it but all of a sudden even though I have my volume muted when I shutdown it still chimes when I start up. I have added no software but I had a crash yesterday where the Mac told me I needed to shut it down. After startup I had a bluescreen crash. Since then I have reinstalled the latest 10.6.8 combo as well as repaired permissions.
I have normal volume control.

It's not one of life's necessities, no. It is an awesome sound though. It's a pick-me-up.
I do find it curious that my old SE, SE30, IIci, LC475, Power Macintoshes 7500 and 8500, and PowerBook G3 always had the startup chime through the external speakers and this machine doesn't.

Help. I have a Google Hangout in 40mins and my sound seems to have vanished. I went to Sys Prefs and it came up with Digital Out....and the Internal Speakers option is no longer there. How do I reboot, or fix this please?

There are many possible causes for this issue. Take each of the following steps that you haven't already tried. Some may not apply to your model. Back up all data before making any changes.
1. Start with the steps recommended in this support article. Don't skip any of the steps. It's the starting point for further efforts to solve the problem.
2. Make sure you have a fully up-to-date installation of OS X.
3. If you've installed an application called "Memory Clean" or any other third-party software that is supposed to "clean" or "purge" memory automatically, remove it according to the developer's instructions and restart. You should do that even if the software is not causing the problem, because it's useless.
4. Other third-party software that has been reported to interfere with sound output includes "Boom" and "Samsung Kies." If applicable, uninstall according to the developer's instructions (not by dragging something to the Trash.)
5. If an AirPlay device is selected for sound output from iTunes (or from other applications via third-party software such as "Airfoil"), deselect it.
6. Launch the application "Audio MIDI Setup" by entering the first few letters of its name in a Spotlight search and selecting it in the results (it should be at the top.) Select Built-in Output from the list on the left. If the Mute boxes are checked, uncheck them.
7. If a red light is visible in the audio-out port when sound should be playing, the internal switch is stuck in the position for digital output. You may be able to free it by inserting and removing a mini-stereo jack of the proper size. If not, the machine needs to be serviced. Inserting any kind of tool in the port may cause damage that won't be covered by the warranty.
If there's no red light, the switch may still be stuck in the headphone position. Try to free it the same way.
8. Disconnect all wired peripherals except keyboard and mouse, if applicable. If more than one display is connected, disconnect all extra ones. Restart and test.
9. If you have a MacBook Air, turn off Bluetooth and restart.
10. Start up in safe mode. Don't log in; just restart as usual when the login screen appears. When you do, make sure the words "Safe Boot" do not appear in the login screen. If they do, the system is still in safe mode and sound won't work.
11. Reset the NVRAM.
12. Reset the SMC.
13. Triple-click anywhere in the line below on this page to select it:
/Library/Preferences/Audio
Right-click or control-click the highlighted line and select
Services ▹ Reveal in Finder (or just Reveal)
from the contextual menu.* A folder should open with an item selected. Move the selected item to the Trash. You may be prompted for your administrator login password. Restart the computer and empty the Trash. Recreate your settings in the Sound preference pane.
*If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination command-C. In the Finder, select
Go ▹ Go to Folder...
from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return.
14. Reinstall OS X after backing up all data.
15. Make a "Genius" appointment at an Apple Store.

Headphone Jack doesn't work and internal speakers are stuck in mute.

So I have an 18' macbook pro with a 2GHz Intel Core i7 and running version Mac OS X (10.7.5). I recently dropped my computer off my lap while my headphones were still in. The headphone jack smashed into the computers headphone output jack I took out the headphones and they still work but now no matter what pair of headphones I use I cannot hear anything when plugged in. As well when I take out the headphones the sound output does not switch back to internal speakers but says Digital Out. I know the speakers work because when I was messing the out jack because I read when a red light is on inside the jack (which it goes on and off) means it is stuck in mute. That however has not worked so far and neither has putting in and taking out the headphone jack.

Anyone have trouble with the internal speakers?

I had my internal speakers reset in May after an update download messed them up. NOw they aren't working again. anyone else having this problem?

Cannot get internal speakers to work. Only works with headphones or external speakers?????

All of a sudden my MacBook Pro internal speakers are not working. The status bar at the top of the screen shows everything bold and in black print but now the speaker volume symbol shows just the gray color and will not allow me to adjust the volume. However, when I plug in headphones or external speakers the symbol becomes bold and black the way it should and everything works just fine??? How do I correct this?

Go step by step and test.
1.Plug in and remove the headphone.
    If you see red light in the headphone port, plug the headphone
    in and out of the port 5 or 6 times to flip the microswitch inside.
    Sound output may be stuck in the digital mode.
2. Reset PRAM. http://support.apple.com/kb/PH14222
    Do this twice
3. Reset SMC.     http://support.apple.com/kb/HT3964
    Choose the method for:     "Resetting SMC on portables with a battery you should not remove on your own".
Best.
