MacBook :: Speaker And Audio In / Out Isn't Working

Aug 24, 2014

The speaker and audio in/out isn't working. Me and my friend were recording music on garage band and got some mic feed back. All of a sudden the speaker and audio ports stopped working. Is it something I can fix on my own or do I have to take the computer into apple and get it fixed.

MacBook, OS X Mavericks (10.9.4)

MacBook Air :: Single Audio Channel - Use Built In Mono Speaker?

Apr 24, 2008

I came across some youtube video with dual-language audio; ie. one language on the left channel and another language on the right channel. The Output page under Sound preference does not have the left/right balance control, probably due to the mono speaker in MBA. If I connect to an external speakers, or headphones, then the balance control re-appears. Is there a way to get around this problem, if I still want to use the build in mono-speaker?

MacBook Pro :: Internal Speaker Not Working Well

I recently started re-using some Logitech Z-4i's with my MacBook. I used these speakers earlier in the year, and they worked well. I use them again, and they are not working well.

MacBook Pro :: One Speaker Not Working For Certain Programs?

Dec 3, 2014

When I either receive or place a FaceTime call on my MacBook Pro, the left speaker cuts out audio and produces high static.  The right speaker is fine.  The receiving end can also hear the static feedback, but their two speakers work fine.  I have all my iOS devices setup to receive and place FaceTime calls (iPhone 5s, iPad, and MacBook Pro 15 inch late 2011).  If I place or receive the FaceTime calls on my iPhone or iPad, there is no problem.   I've tested the speakers, youtube, iTunes audio, streaming websites, netflix, etc... and all works fine on the MacBook Pro.  Just FaceTime.  I also went into system preferences and the speaker setup is correct (audio in and out - internal speakers). I've also restarted, reinstalled Yosemite...still FaceTime left speaker problem.

IMac :: Audio / Speaker Not Functioning?

Mar 29, 2009

Long story short, My iMac stuffed up not long ago so I sent it to Apple to get it fixed (Apple Store Chadstone), I called them a week later, and I�ve been told that they were still working on it. A few days later I called again, they finally found the issue (sort of) and decided to replace the logic board�..anyway, I said OK, they later called me back saying they have replaced it but a new problem occurred, the audio/speaker is not functioning etc� I said well I will just take it back and fix it myself because I need it for �work�, I took it back and this is what I found so far: iMac�s serial number is gone! Oh also, on the repair report paper, it says I purchased this iMac on March 11 2009(March 11 is my birthday BTW), but I actually bought it in Nov 2008, so according to Apple Store, my iMac is now officially out of warranty.

MacBook Pro :: Speaker - Volume Controll Not Working

Aug 9, 2009

I just got the new 15" Macbook Pro a few days ago. My first Mac

Anyway, when I plugged my external speakers into the headphone jack of the MBP, the volume control (both in the Apple bar thing on the top of the screen and the F10/F11 buttons) switched so it would control the external speakers, as it should. The problem started when I unplugged the speakers and went to use the internal speakers again.

And the volume control doesn't work. If I push F11 for volume up, the little screen appears and it looks like the volume is going up, complete with the little water drop sounds, but it doesn't actually adjust the volume. If I plug the speakers back in, it will control the speakers properly, but I can't figure out how to make it control the internal speakers again

I'm sure that if I restarted it would fix itself (probably), but that's a real pain as I am frequently plugging in and unplugging speakers to my laptop.

MacBook Pro :: Built In Speaker Stopped Working?

Jun 21, 2014

I have a 15 inch Early 2011 MacBook Pro w 16GB RAM

I upgraded to OS X 10.9.3 about 6 months ago 

Yesterday I used head phones all day. I do not usually use headphones. 

I closed the lap top over night and this morning the built in speakers are not working. But the headphone work. 

I have rebooted several times. The red light in the head phone jack is not lit. 

When the head phones are not plugged in the System Preferences Sound panel only shows Digital Out and says it has no output controls.

IMac :: ISight Audio Recording Only Through One Speaker

Jul 8, 2010

I am running leopard on an iMac 24" and am having trouble getting my iSight camera to record audio on 2 channels. I have changed my audio input to line in (inbuilt input) in order to record using a better microphone than the inbuilt one in my iMac, and am running a Shure microphone into the input in the back of my iMac via XLR to 1/4" stereo jack cable and then through a 1/4" to 1/8" stereo jack adapter. However when recording video in Photo Booth, iMovie etc. the audio only plays back out of the left speaker. It is not a problem with the output because all of my other sounds (music from itunes for example) play fine out of both left and right speakers. I believe I have run everything into the computer just fine and I can get 2 channels when recording like this in Garageband and Logic.

Intel Mac :: External Speaker Port Not Working?

May 11, 2012

I have a pare of powered KRK Rokit speakers which I connect to my iMac via the headphone port. Never had a problem with this connection, but today the port doesn't seem to be working. 

In normal circumstances, as soon as I plug the speaker cable in the port, the internal speaker of the Mac would disabled itself (even if the KRKs are not powered). However, now I plug the cable it and the internal Mac speaker keeps running. It seems as if the port does not recognise that there is an external source connected.

IMac :: External Speaker Sound Only Coming Out Of One Speaker?

Dec 21, 2009

I have a 2.1 Logitech Z4 setup, and the sound is only coming out of the left speaker. I have checked the wires, they are fine, and both speakers do work - but it could be the socket that's the problem. It's plugged into the line-in socket, I have put the output in System Preferences to Headphones, and everything is inserted correctly.

What do I do?

EDIT: My sound system is plugged into the headphones jack. I have tried putting headphones into the headphone jack and the sound also only comes out of the left earbud.

Software :: Audio On MacBook Not Working

Sep 21, 2010

So I have the red light showing from my audio port on my macbook. I know this means there is a problem with my audio. And there is - I can't play sound from my internal speakers. When I try to adjust the volume control using F11 and F12 buttons (on standard macbook keyboard) I am unable to, and I have the little "no smoking"/"do not enter"-type logo underneath the volume control when I am trying to change the volume. I have tried to go into system pref -> sound -> and under the "sound effects" tab change the 'Play alerts and sound effects through:" option to 'internal speakers'.

But I am unable to select any options from that pull down menu. I also know others that have said, 'just put a toothpick or paperclip in your audio output port to get rid of the red light' - well I tried that and the problem persists. I am able to listen to sounds fine when i have headphones on, but as soon as i take out my headphones- no internal speakers. I have also done the obvious - restart/shut down and wait a few minutes- option, and making sure my applications aren't muted. I also did a SMC reset, and that didn't work

I tried everything, it just doesn't work at all, i plugged in the microphone and changed the system preferences manually and did everything with all the applications, but still, nothing is working. I have had this MacBook for 2 weeks now. I wish I waited couple of days for the pro.

MacBook :: Headphone With Mic Not Working In Audio Input

Mar 23, 2012

This headphone/headset that is equipped with a mic does not work properly when I connect it to the audio input opening. The headphone/headset is only equipped with one plug (is this the proper term?). 

When I adjust the audio setting (apple icon--> System Preferences --> Sound --> select "Input" tab --> highlight " Line in; Audio line-in port") I can only hear sounds through the headphone but the mic portion does not pic up. If I hit the mic portion I see the bars move, that would indicate some sound being picked up. However, when I try to use the mic, through Mac Office Powerpoint 2010, the sound (if received through the mic) does not pick up. 

Why is this happening? Do I need some extra external component for the microphone part of the headset to work or do something extra in the System Preference area?

MacBook, Mac OS X (10.6.8)

MacBook Air :: Sound Stops Working When Try To Run Anything With Audio

Aug 20, 2014

I noticed my sound wasn't working, so I did a restart. The "blip" sound when you adjust the volume using F11/F12 would play, but as soon as I tried to run something else (YouTube video, iTunes, etc.), that wouldn't play (just get stuck at whatever point I tried to start it). After that, the blip sound no longer worked either. 

I have tried the following things already and none of them fixed the problem (all of them reset the "blip" sound, but it always went away again as soon as I tried to play anything):- running Apple Diagnostics (no problem detected)- resetting PRAM- resetting SMC 

I've checked things as suggested in other message boards … there's no red light in my headphone jack, nor is the sound muted under System Preferences. The problem persists whether headphones are in or not.

MacBook Pro :: Detecting Headphones But Audio Isn't Working

MacBook :: Audio Stopped Working But Showing Everything Normal

Jan 8, 2010

The audio on my 2006 MacBook has recently stopped working. I thought the internal speakers might have blown, but the audio doesn't work even if I use headphones or external speakers through the headphone jack.
When I use the volume control buttons, everything looks normal - I don't get that symbol that it seems most people do when their audio isn't working. The levels will go up and down but without the sound usually associated with the volume control. I checked out the sound option in System Preferences, and everything is normal. I'm running OS X version 10.4.11. I've tried rebooting and nothing changes. All the other threads I've seen seem to have that symbol when using the volume control, or something is different under System Preferences, but everything is normal.

MacBook Pro :: External Speakers Not Working - Intermittent Audio

May 20, 2012

I have owned my MacBook Pro since June 2010, and have always used a pair of independently powered (via adapter) external Dell speakers for audio output. Since upgrading to Lion about 1 month ago, I was having intermittent audio issues, which were resolved by re-starting my computer (not ideal but it worked). Today, the speakers just stopped working. The internal speakers work, but when I plug the externals into the headphone port, they don't produce sound. Earbuds in the same port also don't work (but the earbuds are good). The external speakers are being recognized by the sound panel in system preferences.

MacBook Pro :: Audio POP Before Hearing Actual Sound / System Sounds Not Working Fine

Mar 31, 2009

Here is whats happening: my 3 y.o. 15 MBP is connected to external speakers (Bose MusicMonitor) and every time there is a sound, any system sound, say an email in, a volume chirp, or a Skype chirp, anything at all, I hear an audible POP, before hearing the actual sound, in fact the POP sort of overlays the sound. I hear the second POP sometimes, after the sound has sounded, so to speak, and sometimes the second one does not happen at all. To me it reminds me of the Pioneer Amp my dad used to have in the 70's, when you first turn that thing on, it would produce an audible POP. So, back to to this, it sounds like an amplifier POP by being awaken by the system, and I'm inclined to think it is the MBP's audio "amplifier" on its board. Oh, btw, both the speakers and the MBP's volume is set to low.

OS X :: Audio Not Working With 10.5.8

Aug 18, 2009

I just finished installing iATKOS v7 (10.5.7) and then installed the software update, all with success. (So now my system is 10.5.8). The thing is, my audio doesn't seem to be working. I don't know what kind of audio driver I have. I even went to System Profiler but it tells me I have no built-in audio, and neither does System Preferences. Does anyone know a way to detect what kind of sound driver you're using, so that I can find the drivers/kext for it? If not, any Terminal commands or any other ways I can get this to be fixed?
