Volume problems on my Apple MacBook

Whenever I push the volume buttons, I get the little volume bars, with the volume symbol above, but there's no sound.  Below it is the no symbol.

    No there isn't.  However, when I put head phones in, the volume works, but it's obviously only heard through the headphones.

    I have same problem.  Sometimes there is even a red light glowing from the headphone jack.

If you are getting a big 'NO' symbol when using the volume keys to adjust it, it means your speakers are not being recognized as a valid output source.

Try resetting your SMC:

If that doesn't work, it will likely need repair. Call 1-800-MY-APPLE if issue persists after resetting the SMC.

I have mac book with volume keys. I try to switch


There is a problem with your audio jack. It thinks that the optical link is plugged in. Look into the jack and you'll see there is a red light for the optical link. Try to clean the jack, if you see and contacts that are recesssed, try to pull them back using a tooth pick. If that fails, the jack needs replacement. Here is an Macbook Repair Guide that shows how to open a Macbook. If you want somebody else to do it for you go to Macbook Repair.

I laughed when I saw this (NOT AT YOU, only because I had just finished answering this question for a MacBook Air). Just so you know, this is a VERY common problem among MacBooks. I own a MacBook repair shop and I see it quite a bit. it has even happened to my own MacBook Pro and Standard 2.4 GHZ MacBook. Usually this problem is accompanied by a little red light inside the earphone jack but not always.
Get a can of compressed air (for dusting of computers/electrical components) and attach the small straw that is supplied with the can.
Next, insert the other end of the straw into the EARPHONE jack. No need to jam it in there. Just insert it about 1/4 inch. Now spray a blast of air inside the jack a few times. Each time you do this, TRY THE VOLUME BUTTONS. They will work! This doesn't harm the computer and will not void the warranty. Plus it will only cost you about $3 to fix. It may take a few times but it WILL work. Here is my email if you have further questions and don't forget to vote if when this helps you: i_Patch.securepath@live.com

Volume controls problem


There are options in System Preferences :: Sound for a volume slider in the menu bar and in Displays for the brightness slider. This can get you by but your keys seem to be remapped--check Keyboard & Mouse that your shortcuts are not changed and you are not using them for F1.... (Restore should have fixed that.) -Ken

Volume problems on my Apple MacBook


Hi, Sorry you are having problems,
If I understand you correctly, you have your headphones plugged into the MacBook and are expecting sound to come out of your speekers ?
Well, if that is the case, you must know that the mac will automatically cut the signal to the speekers as soon as headphones are connected.
Now if you are saying that you connected the headphones to test it and found that whe you changed the volume, you could hear the change on the headphones, but when you unplug your head phones, you do not notice any sound difference on the speakers.
SO let's say that is the problem. First thing to always do, of course, is a full shut down and a clean start up with no headphones installed. Once you have booted up, try it again....
If it still does not work, go into your sound preferece pane in the system preferences and change some of the settings, like muting the sound and clicking the button that allows for showing volume in menu bar, unclick options go into the tabs go clicking and unclicking things... then quit and then go back into the sound preferences and set it the way you want, sometimes shaking it up a bit gets it back on track...
Good luck.

Volume Problem on Apple Laptop


Sounds like the volume is muted. Right click on the speaker icon and it should allow you to un-mute it. If that does not work, you need to download or reinstall your sound drivers. If you do not have the cd you can get the sound drivers from the apple website.

I hope this helps. Please rate.

This also happened to me after unplugging some headphones. After reading this, I opted for putting the headphones back in instead of a toothpick. This fixed it.

I have a philips Matchline tv (29pt6361/79r) the tv works fine except it automatically turns the volume down without any buttons on the remote or tv being pushed


well depends on how far it turns the volume down as to what the cause is and if the volume bar on screen display comes on when the vol. goes down. if it just goes down a little you probably have the "smart sound" setting turned on in the audio menu turn it off and see if prob. goes away. if the vol. bar comes on the screen whenever the vol. goes down the you most likely have a bad button on your front panel and it doesn't have to be the vol. down button. it you think it is the button it would need solder work to be changed most likely shop job.
