Intel Mac :: No Sound On Internal Speakers In ITunes
Jun 15, 2012
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.
Info:
iMac2.16 Ghz intel core 2 duo, Mac OS X (10.5.6), Memory 1 GB 667 Mhz DDR2 SDRAM
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.
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?
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.
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.
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...
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. Apple iBook Notebook 12.1" M9846LL/A (1.33 GHz PowerPC G4, 512 MB DDR SDRAM, 40 GB Hard Drive, Combo Drive, Built-in AirPort Extreme
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'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
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 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?
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.
I usually listen to any output from my iMac (Intel Core 2 Duo 3.06GHz, 27", early 2010) through an external amp and speakers, via the analog output (headphone socket). However - I recently disconnected the jack plug to listen through the machine's internal speakers but was greeted with silence. I checked the volume via the kb controls - the mini display appeared on screen suggesting that the volume was set on full, though I could not adjust it at all. I reconnected the jack plug and sound came out from my external speakers as usual. On disconnection, no volume. I searched the forums for ideas, and came across this support article: [url],,, which I followed to the letter.
When I open 'Sounds' in System Preferences, the only output option available to me is 'Digital Out' - there is no option for internal speakers or headphones. However, if I plug in the line-out jack, the options change - only 'Headphones' is available (no 'Digital Out' any more). Following the article, I checked to see if there was a red light in the digital output socket, which there is not.
Line-in external tape recorder produces VU sound level fluctuations but the sound doesn't come out the internal speakers. iTunes and Internet sources play OK.
I have a 27" mid-2011 iMac - today I upgraded it to 16GB RAM and added an SSD (in addition to the existing hard drive). The memory upgrade I performed myself but the SSD upgrade was done by a qualified tech.Now my internal speakers no longer appear as an audio output device, instead I have a "digital out / optical digital-out port".
I cannot adjust the volume (my menu bar volume icon is greyed out) and no sound plays either through the speakers or connected headphones once I login, however I hear the startup chime when I first turn it on, so this doesn't appear to be a hardware problem - it is perhaps a driver issue?
Is there any way I can rectify this without reinstalling OS X? I plan to install Yosemite on the SSD once it's out but would prefer to wait rather than installing Mavericks on it first.I have already tried resetting my SMC, resetting my PRAM a few times and also reinstalled the 10.9.4 combo update, but neither have resulted in any changes.
I feel like I once had a PrefPane for this problem but just am having a hard time searching for it. Currently I have my heaphones jack Line-In routed to my AV Receiver for iTunes music in my room, but whenever I am YouTubing or other stuff while listening to music the System Sounds come out of my Loudspeakers too. I am interested in routing only the iTunes audio through the headphone jack, and everything else to run through my iMac's internal speakers (2007 iMac AL).I saw the SoundFlower thing out there but didn't think that was the ticket
After I pulled out the jack for my speakers the volume icon was greyed out [URL]and soon I realized that internal speakers as such have been disabled from the system [URL]When I restart the startup chime is played as usual.Is it a hardware or software thing?
I bought a 5.1 set (a basic one without optical out) and I also bought the Muse pocket lt (usb soundcard) to plug in all my speakers at once. The soundcard is working perfectly but I want audio trough every speaker and not just the 2 front speakers. I wonder if there is a plugin for iTunes or OSX in general that makes the audio goes trough every speaker. It may sound stupit but the main reason I bought 5.1 is because I wanted speakers playing all around my room
Situation: no sound out from speakers in admin and user account and newly created account. Headphones work, startup chimes work on speakers.
Go to Sound in Preferences and only shows Digital Out for output. Should show Internal Speakers. Ran Diskwarrior and Applejack and zapped pram. Took mac apart and confirmed speakers wired correctly which is verified by the start up chimes being audible on the internal speakers. tested all accounts and created new account all with the same results. Did search of Google and MacRumor. Found one unaswered post indicating same problem. Had same problem with another macbook pro, ran same steps, take apart, confirm wiring setup, Diskwarriored, applejacked and zapped pram and it fixed the problem. I'm not sure what else to try. Did check Audio Midi Setup util and it also did not see the internal speakers.
I am using an IMAC. I am facing the problem that sound is not coming from the inbuilt speakers. When i press the sound keys on the keyboard muted sign comes on the screen. I also chkd the system preferences but all options are Ok. I am unable to understand the problem. Either it is of the speakers, the keyboard or any hardware error?
