Sound not recignizing my internal speakers

Hi: My parents iMac is not recignizing the internal speakers in their Mac. When we try to change the volume, it has a cirlce that is crossed out. Any help would be great
Thanks

Except for your keyboard & mouse, disconnect all devices/peripherals from your computer.
Double check the link MGW listed & make sure the following is your set up:
Change the Audio Output setting to +_44100.0 Hz_.+
Trash the com.apple.soundpref.plist document
Boot from your System Install DVD & run the repair disk/repair permission options.
After doing the above reset the SMU - http://docs.info.apple.com/article.html?artnum=301733 iMac G5: How to Reset the SMU (iMac G5, the iMac G5 (Ambient Light Sensor), and the iMac G5 (iSight)).
Say 3 Hail Marys, make an offering to Buddah, Praise Be To Allah, sacrafice your first born & last but not least, kiss your iMac (gotta cover all bases).
Good luck!

Sound not playing through internal speakers or headphones

Okay, so I am wanting to listen to audio, but it is not working through my speakers or headphones. Last time that this happened, I know that it had something to do with airplay, since I remember doing something with airplay. I have no idea what is causing this this time, but if you need any additional details, just ask.

Have you tried a PRAM reset?

Sound Preferences: switches from Internal Speakers to Digital Out

I've been having this problem recently. I sent the computer off to Apple a few weeks ago and it helped for a while, but no longer.
My computer has a problem with it's sound output jack or something. Without inserting anything into the plug, the Sound will change for "Internal Speakers" to "Digital Out" and to "Built-in Output" in the Sound Preferences Panel.
Any suggestions?

I have a 4 month old macbook and experiencing the same problem. Just realized it after installing itunes 8 and since then having a stuttering audio playback problem too. When i plug my headphones into the audiojack the sound switches from headphones to speakers and back as well as itunes playing tracks in a stop and go mode. I repaired the rights several times, installed quicktime 7.5.5 again, reinstalled itunes 8 and for sure running the latest leopard version 10.5.5.
Also thought it could be a hardware problem but after reading this it seems more software related.
Any idea?

Using Mountain Lion iOS and audio output will not change from internal speakers to AppleTV so that sound can come from TV speakers, why??

I am using Mountain Lion iOS and trying to connect my MacBook Pro to my plasma TV using AppleTV and AirPlay mirroring. The video does just fine. However, there is no audio coming from the TV. After activating AirPlay I try to select Apple TV as the audio output in System Preferences and it highlights it but then immediately goes back to Internal Speakers and only has sound coming from the MacBook Pro..
What's going wrong ?????

Are you sure that WIFI network doesn't have an AppleTV on it? Just because you don't own it doesn't mean there isn't one on that network. The laptop or better said the OS cannot differentiate between an AppleTV that you own or not. If it sees one on the network, it will show you one as being available. The automatic reconnection is happening probably because the last time you streamed to an AppleTV, you didn't drop that connection before sleeping the computer or shutting down iTunes.

I am unable to get any sound out of my internal speakers and no options to use them are available. Plus the mute box is ticked and greyed out and will not untick

How can I get sound from my internal speakers. I have not set or adjusted any sound levels but all sound is muted and am unable to untick the mute box. I had sound when I bought the machine but now nothing, not even an option to select internal soeakers in Souns setup!!

1. Reset PRAM. http://support.apple.com/kb/PH4405
2. 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".
3. Applications > Utilities > Audio MIDI Setup
    Audio Devices window
    Side Bar
    Click the Built-in Output.
    Under Mute any of the boxes checked? If so, uncheck it.

IMac not detecting the internal speakers

I am new to Apple and just got an iMac. Sounds worked initially, but stopped after a software update. The internal speakers aren't being detected. Tried to reset the PRAM and unplug the system. Any suggestions??? Thanks.

Are you sure you did the smc and pram reset correctly?
Short of removing the audio plists in /Library/Audio I am not sure what the problem is at the moment.
By the way, look at the More Like This section on the right side of these pages for the similar problem.

Explosive sounds from macbook before internal speakers going out TWICE

Hey guys,
So my internal speakers stopped working about a week ago, and a few hours before that my laptop started making weird sounds - it sounded like a mini war was going on inside my computer.. explosive sounds (i know it sounds silly but my friend was there and he heard it too). Then a few hours later, my internal speakers stopped working, AND my headphones wouldn't work either. There is no red light flashing in the headphone jack..
But a few hours later after restarting and shutting off my computer a few times, the sound came back again! The explosive sounds stopped happening.. until a few days later when i heard the sounds AGAIN. And of course, my internal speakers are dead once again.
Everything else on my laptop is fine. Nothing is corrupted, my applications are running smoothly. I'm guessing because the sound is out, videos are not playing either. It would load, but it won't play. Same with iTunes. Even if I select a song, it won't play!
I also ran the hardware test on my laptop twice. Once it's the short version, the second time was the extended version. Both times the results were normal, that there's nothing wrong with my hardware.
Someone please help me! What else can I try?
-Steph

Weirdness, I opened that, but the main volume slider for that is greyed out no matter what I do. It's all weird:

Anybody have any idea what's up?

Line out and Sound Effects revert to Internal Speakers when I reboot. Any suggestions?

I have an early 2008 Mac Pro that runs fine under Yosemite. The Sound preference panel worked under Mavericks, but now I must open the Sound panel and manually change the output for both Output and Sound Effects from Internal Speakers to Line Out after a reboot. This is irritating and is becoming more so.
I've zapped the PRAM with no success.
Would an AppleScript app on startup work? I can't seem to find any appropriate commands in AppleScript that affect these parameters.
Any help appreciated.

The script doesn't seem to work on Yosemite. Trolling around in the library, it appears that "audio" is now "sound," which would explain the file not found.
Or am I missing something?
Suggestions?

ThinkPad T430s No Sound Through Headphones or Internal Speakers

My laptop is unable to play sound through both headphones/earphones and its internal speakers.
I downloaded and installed the Realtek High Definition Audio Driver from the following site: http://support.lenovo.com/us/en/products/laptops-and-netbooks/thinkpad-t-series-laptops/thinkpad-t43... .
As a result, the Device Manager shows that the HD Audio Device is working properly.
Also, there is a green check mark over the internal speakers icon and headphones icon (when I plug the headphones into the jack), which was not present before I installed the Realtek Driver.
However, there is still an "X" over the audio icon in the taskbar.
When I click on the audio icon, the following window appears, stating that the audio device is disabled.
I have went through various forums and solutions, but none have been helpful so far.
Thank you so much for your time and help for this issue!

The Unknown Device seems to have disappeared from my Device Manager when I restarted my laptop. However, the HD Audio Device is still there.
My audio stopped working around December 23, 2014. Since then, I have tried to find solutions on various other sites. But, when I search for the System Restore, it only brings up a recent Windows Update.
Roll Back for the HD Audio Device is greyed out.
Also, after uninstalling the HD Audio Device and rebooting Windows, this dialog appears, mentioning that the Unidentified Device is something that was unplugged, which I think are the headphones. Also, there was a Failed installation for the Audio Device.
Thanks so much for helping me look into this problem.

No metronome sound out of the internal speakers

Hi everybody,
there's no metronome sound coming out of the internal speaker of my Mac while playback.
All settings are fine (play while playback, use internal speakers, "Klopfgeist" switched off) and it worked well with the same settings in Logic Express 7.
Please help!
best regards

yes, its set on All.
The Klopfgeist sound comes via the Interface with the rest of the sounds, but it should be only on the internal speakers (earohone)
It's a setup for live-performance (drummer gets the Click via earphones), sound via interface for the audiance

HP 4330s SRS Premium Sound not working with External Speakers

And this is my second topic and rant!
The SRS Premium sound driver doesn't work with USB Speakers.
It doesn't work with Bluetooth speakers either!
In other words it only works with the Laptop speakers.
ARE YOU KIDDING ME!
SRS Premium sound for Deeper Bass and Clear sound enhancement bla bla bla now in you HP Laptop
but ONLY with your LAPTOP SPEAKERS!
ARE YOU KIDDING ME!
DEEP BASS on these cell phone speakers!!! Really???
Why doesn't the SRS Premium Sound driver work with external speakers!
I believe I have used SRS Sandbox before and ALL THE SOUND was directed to that driver and it worked with everything!
WHY DOESN'T YOUR HP DRIVER WORK WITH EXTERNAL SPEAKERS!
Is everyone in HP a bloody RETARD?
FIX YOUR DRIVERS!
End of rant!

Oh BTW {Content Removed: rant} http://www.srslabs.com/landing.aspx?id=693#23
23. Will the SRS Audio Sandbox work with my USB speakers or Bluetooth speakers?
Yes, the current version, 1.6.6.0 will work. If you have a previous version that is not working with these speakers, please upgrade to this version.
Do you have anything else to share with me {Content Removed: rant}

Sound out reverts to internal speakers at every shut down

Everytime I turn on my Mac Pro I have to go to System Preferences and change the sound to Line out. Every time I shut down the sound out defaults to the internal speakers. is there anyway to stop this?

Things you can try.
1. Smc and pram resets.
2. See if you can get it to "stick" by setting the sound out preference with Audio MIDI Setup (in your Utilitiles folder).
3. Last resort -- temporarily remove the two plists in /Library/Preferences/Audio.

Sound Output reverts to Internal Speakers every time I log in

Hello all,
I have a Mac Pro 2,1 and just installed update 10.6.2 and every time I restart or power it up, it will revert sound from Digital Out to Internal Speakers.
Later I created a new account, logged out and logged back in and sound was also reverted to internal speakers.
I have another internal hard drive with 10.6.1 and don't have this issue.
Does anyone know how I can submit a bug-report to Apple?
Thanks,

See this thread for some things to try:

Sound not working on ipad speakers, shows headphones and no headphone is plugged in.

My sound is not working on my ipad2 speakers. when I adjust the sound button it shows headphones, I have no headphone installed. I tried reseting the ipad (turned off and on), reset with itunes, updated os.

Hello,
As per the information you have provided it appears that the audio port has been damaged. Make sure that there is no issues with the port, if there is no damage on the ports, you can get the iPad replaced under warranty.
Resetting and restore would not work as this mostly appears to be a hardware failure.
Thanks and regards
