OS X V10.7 Lion :: Sound Not Working - No Option To Select Internal Speakers
Apr 25, 2012
I use a MacBook Pro and until today the sound worked fine. All of a sudden the sound doesn't work, having checked the sound settings there is no option to select internal speakers the only available option is 'Optical digital out port'.
A week ago my internal speakers disappeared from audio outputs on my 1G MBA (1.6/80gb). they would come back with a restart for a while, but now there just gone.
Another thing that is happening is that when the speakers are "missing", quicktime video is choppy, as is streamed video (like youtube). I also tried the garage band analysis and got the "Core Audio Selected Driver not found.(-10202)" message.
Other then these things, the computer is functioning flawlessly...
Yesterday I use my headphones to listen music from my mac. Today after I turn on my notebook I saw that my sound icon is grey and when I try to change the level of the sound nothing happens. When I put again my headphones the sound works.
I also saw that I have no option to choose Internal Speakers in Sound menu.
For reasons unknown the internal sound option has disappeared from my MBA. The little speaker icon on the menu bar is grayed out and nothing comes from the jack. Internal speakers don't even show up as an option under sound output. I do use an Airport Express for external speakers but it's been playing happily with the internal speakers for months.
I was watching a movie on the bus using my headphones earlier today, and when I got home just now, the internal speakers aren't working. There is a red light coming from the headphone port and the volume can not be adjusted. Is there a software fix, or do I have to take this thing to the genius bar? I restarted the computer, still no dice.
the ONLY output device listed in my system preferences is Digital Output with Optical Digital-Out Port. I NEVER used headphones or any external speakers. I don't know what turned the Internal Speakers OFF But I would like to turn them back on. I can't find any thing any where in the OS that would do that. Any one has ANY Clue to why this would happen?
My iMac 27" 2.7 GHz Inter Core i5 has just stopped producing sound. The speakers seem to work fine, because I can hear the startup sound, but nothing comes out of iTunes, Youtube, Quicktime, DVDs or any other medium.
There is no sound coming out of my speakers- internal or external. This problem just recently happened (I didn't get my MacBook Pro with this problem). I have checked and double-checked the sound preferences. Nothing is muted or anything and the correct "device for output" is selected.
I have checked all sound levels including Audio Midi in utilities. In system preference the output is Digital Optical and nothing else is available to select. It also says this sound output has no controls - is this correct? The sound icon in the menu top right is greyed out and I can't adjust the level. I have an Apple TV and have turned off airplay on that? Also have checked computer speakers (not Apple TV) in iTunes. I had this problem before but rebooting fixed it. My son plays Minecraft on this computer and watches millions of uTube stuff. He may have used his earphones then. Could this be the problem? Nothing is muted in sys pref or utilities audio midi. The chimes work when starting up. The mic sound levels are moving.

My Macbook has suddenly stopped having internal speakers in the sound preferences.When I turn it on, it plays that familiar synth chord sound to say all is ok, but it wont play any audio. So videos and itunes etc play but the sound isn't produced.When I try to turn the volume up or down, the indicator says the volume is up full, but I cannot adjust it. Underneath the volume measurement there is a little sign in white like a no entry sign, meaning that adjustment of volume is not available.I gues this must mean that the speakers have been disabled, but can't figure out how to enable them.
One day I come home, turn on my mac, try to play music and theres no sound ! looked into the sound preferences and internal speakers are no longer one of the options. I tried all the solutions mentioned ; take off all external sources, tried plugging in and out the headphones 50 times, restarted OS, installed the latest software and still nothing. Did anyone face this problem and try eeeverything and nothing works
4. The same machine when booted in Windows (via Bootcamp/CSM-BIOS) plays perfectly and shows Cirrus Logic devices and the HDA devices. This should eliminate hardware issues.
5. I have checked for the Optical Audio microswitch being stuck, but that does not seem to be the case.
6. This was used with Apple Headphones which also have the microphone built-in [URL] ....

Comparing it to another 13" Mid 2012 MBP which has working sound.Â
Saw a problem a member (steelfist) had awhile back regarding loss of sound from internal speakers. I needed to know how that was resolved since I have the exact problem on wife's ibook.

Problem: Internal speaker option in sound preferences GONE all of a sudden. Only headphone option exists. Headphones sound good and so does any external speaker plugged in to that jack. But internal speakers are gone.
Tried: everything except reinstalling OS X. I've messed with opening and closing Garage Band, checked Midi defaults, tried to trip jack into not thinking headphones was plugged in - did the PRAM, power reset - no mutes on or sound lever out of balance either. Want to avoid sending unit in for repair if I can do it myself.
Need to know: Would opening the unit and unplugging / plugging the sound jack or speakers (if possible) make the system "see" the internal speakers? Or should I reinstall operating system? Just afraid of losing files.
I have my stereo plugged into the headphone jack but would like the sound to also come from the internal speakers when the stereo is off without unplugging the jack in back.I tried going to the sound control panel but it only lists the headphone jack. Is there a way to do this?
I've been unable to get sound from internal speakers of headphones on MacBookPro. Did updates, restarted several times, it's not muted, I can adjust volume control, settings are set for internal speakers, can't even hear an itunes song
A headphone jack got stuck in my macbook pro as it fell down in a plane going thru turbulences (lucky me!).So that now it thinks there are headphones connected while there is nothing...I wont be anywhere near an apple store for the next month so I was just wondering if it was possible to force the use of the internal speakers over the output jack?
Sound isn't coming out of my internal speakers. When I hook up headphones everything is fine, but when I'm on the computer itself, no sound comes out, a red light is coming from my headphone jack, and the volume controls don't do anything (volume stays at max and there's a white circle with diagonal sign thru it, like a no smoking sign) and I don't get sound.
So the sound on my Macbook Pro is NOT working. I went to the sound settings and the internal speakers option under output is gone. I reset the PRAM and when it did its "second boot", the apple sound played just fine. As soon as I logged in again, the option is still gone and I am getting no sound.
My internal speakers in my PowerPC G4 just magically stopped working! It recognizes them in system preferences. And yes, the volume is up. I dont know what happened. The headphones do work. I havent tested external speakers yet, but that's next on the list.
This may appear to be a hardware issue, but I'm of the opinion that it will prove to be a software problem, so I'd appreciate it if the topic was left here. Over the past couple of days I've had problems with getting the internal speakers on my 1.33ghz PB to work while I've been logged into my user area (the only user area on the computer). When the computer is initially booted up I hear the usual boing! but once I'm signed in I can't get any sound out of the speakers. I've been to 'Sound' in System Preferences and checked that all of the settings are correct and that Mute isn't selected, and everything appears to be ok. I've also tried inserting a movie DVD to see if this changes anything, but the DVD starts a plays the video, but still no sound.
I haven't dropped the computer, or spilt water on it, so I would think it is almost definitely a software issue (backed up by the fact that I get the initial BOING!! sound). I never play the speakers at full volume so I would very much doubt that they'd be shot either. I've tried shutting down and restarting the computer, but this does not always fix the problem. A perfect example of how erratic the problem is that when I booted the computer around 10 minutes ago there was no sound - tried playing music in iTunes and nothing... I've just started iTunes and wahey - music playing through the speakers! Also, last night while playing a DVD, the sound was perfect for a good 20 minutes or so, but then all sound from the speakers was lost and only the video was running.
I recently installed XP with bootcamp on my MacBook Pro. The big problem I'm having is that the internal speakers on my computer don't have sound coming out of them. (When I'm on windows) The volume control on my keyboard doesn't do anything, either. When I go to find my sound control, to make sure it's not muted or anything, I find that I can't even edit the sound controls. It says I don't have a device that can output sound, even though my internal speakers work fine on my mac desktop. It can't seem to find my internal speakers, when I try setting up a new device. I'm having a lot of trouble setting up internet on the XP as well, I just don't understand how to do it. (I've used mac all my life, I am really new to windows.) Basically, I have a wireless internet connection, I've got the router downstairs, and the information is handy. But I just don't know how to set it up, and I don't know what type of internet connection I want.
I had my computer plugged into some external computer speakers (nothing where I had to downlaod any software, I have used these speakers before), and when I removed them, all of a sudden the built in speakers weren't working. I tried to adjust the vollume, but I get the volume image with a little "forbidden" circle and cross underneath. I tried adjusting the settings in System Preferences, but when I got to the audio settings there was only the one "Optical digital-out port". I then updated my computer, but still no luck. Lastly I went to Utilities and to Audio Midi Setup to reset everything to the default settings, but I am unable to adjust everything. It's all that lighter shade of grey that tells me I can't select it.Â
The volume quit working on my computers speakers. I try to hit the up volume and a greyed out speaker appears showing volume bar all the way up with a circle below it with a line through it?
The sound output in my Macbook Pro has been going in and out now for a number of months. And yesterday it finally got stuck on "Digital Output" meaning when I take out headphones from the jack, the internal speakers do not work. I am planning on taking it in and wanted to know, since I am still under warranty will Apple repair it, or give me a new one?
