MacBook Pro :: No Sound From Audio Output
Apr 14, 2010
I've had a problem with my MacBook Pro (2008) for a while. If I connect a headset or external speakers, there will be no sound from the Macs audio output. The built in speakers is working perfectly. Do you have any idears what could be the reason? I tryed do reset the Pram but with no luck. If it helps there is no red light coming out of the macs output. The problem occurred when I connected a mini-jack for my speakers. Maybe the output thinks it's a S/PDIF and not a normal audio output?

I had a 3,5 mm stereo jack in my audio output on my macbook, and it broke inside. Is it possible to redirect the sound output to go through the input jack?

I recently bought a 2009 Mac Pro. Now, I'm trying to setup a small bedroom home theater. And sound is still my main problem here. I used my Mac Pro mainly for doing graphic works, listening to music, watching movie, and gaming sometimes.
Here is what I currently have.
8-Core Mac Pro
40" 1080p LCD TV for Movie
24" LCD for doing graphic work
Harman Kardon Sound sticks (trying to get rid of this and replace it with a 5.1 or 7.1 system)
And here is what I'm buying
5.1 or 7.1 Receiver
Speakers
My plan is to get audio out through the optical output. But according to several articles I read online, optical output does not transmit audio when I play music on iTunes or play games (in BootCamp), is it true? So far, I couldn't find any sound card (internal or external) which work for mac pro that has 3 analog 5.1 signal output which I can use with standard 5.1 speakers. The only things I found is the Creative DDTS-100 and the FireWire which were all discontinued. What other options do I have?

My sound keeps turning off. When I check the settings, the output device switches randomly between Internal and Digital output. I have no idea where the Digitial Output is coming from and this started about a month again. It switches randomly and then I loose all sound for a few seconds. Sometimes it happens once then stops for a few days, other times it switches back and forth for 5 min. No idea!!!Â

For some reason, I can't get Logic Express 8 to output audio to my Mac's attached speakers. It outputs fine through my M-Audio interface, though, but I'd just like to listen without headphones.

This started happening randomly earlier tonight, and I haven't managed to find a fix just yet.I was encoding a video file for quite awhile (I don't think that parts important, but I thought I'd include it anyway) and then I tried to play a youtube video. I noticed there was no sound, so I tried to up the volume using the Volume Up key on the keyboard. The volume visualisation appeared on the screen like normal (albeit a bit laggy), but the sound still didn't change, neither did I get the usual 'click' noise you get when you change the volume.I went looking into the sound options in the system prefs. only to find that the Output Sound device was headphones. For a test I plugged in some headphones to see what happened and, low and behold, the Output Sound device changed to the Internal Sound and my speakers were working again, but only with the headphones plugged in.

I have a white Macbook, Intel Core Duo 2, 2 Gb Ram. (October 2008) Under Leopard, my volume (audio output is a shame); under bootcamp with Windows XP on the hard drive, volume is almost double: is there any work around on this?

I just bought a converter cable to be able to put things from my laptop onto the TV. More specifically, I bought this one: [URL]
I've read the reviews and they were all really great. The cable is excellent for images; however, I cannot for the life of me figure out how to do the sound.
The reviews said that the audio output option under system preferences should show up with the receiver, but all it has is my computer speakers.

My audio headphone jack is not working anymore and I want to use my line-in as my audio out. Since I don't use them that much. So I can use headphones/speakers again.

I own a 2011 Macbook Pro and as stated above I can only hear out of my left ear. I've tried multiple headphones, checked the settings and tried changing the balance and it completely shuts down the music if I move it over to the right ear. I am running OS X Lion as extra information.

Well i'm progressing with my connecting the Mac to the TV... Have the video going fine with the Mini DVI to HDMI but for the life of me I can't get the audio output going. I have the 3.5mm RCA jack cable in the output from the Mac and the computer has recognized that it's plugged in and comes up at headphones. Now the problem is getting the TV recognize the audio input.Â
I've read elsewhere that there should be a way to set the TV to allow a video HDMI input along with an analouge audio signal.Â

I was using my 13" White Macbook (Spring 07) all day today, listening to music on headphones while working. I brought my computer over to a friend's house and attempting to line out some audio from Garage Band to speakers through the headphone jack and suddenly all audio began to have skips & spaces every second or so. I can still the hear songs but they are constantly interrupted. I tried Itunes & audio from the internet, and two different pairs of headphones I know work. Same problem every time. The strange thing is that the audio works perfectly out of the internal speakers. Has anyone had this same problem? I haven't seen anything on the web that was similar. I tried the Q-Tip/Toothpick trick suggested on a bunch of other threads. But I don't think it's an issue of the computer not adjusting to the headphone setting. Also tried to resetting the battery, but that didn't work either.

I have purchased a optical audio cable to hook up my 15" mbp to my LCD.One end is the toslink and the other end is the toslink adapter, when I put both end into its place. The speaker icon turns gray and I cannot adjust the sound level and the music stops from the laptop speaker.Also, the optical digital audio out option is not showing up in audio preference.

I recently had a cracked panel on an old Macbook Pro 15 inch (A1260) and just replaced it with a new one. Ever since i replaced it i have had no sound. Now i consider myself an experienced mac user so i have checked under my sound prefences and it doesnt list anything under sound input or output and things are grayed out. I also had the guy who replaced my panel, who is also my friend, check everything out and he hasn't been able to figure out why there is no sound. he gave me a usb midi device that shows up and works but when unplugged theres nothing.Â
Another thing that has started is, video online will stop every 11 seconds, and thats with me clicking on the bar when it stops playing after the first 11 seconds.

I woke up this morning and tried to watch a linked video on a webpage. I saw the video, but there was no sound (this had not been a problem the evening before). I am using USB soundsticks, so I checked to make sure that they were plugged in, and they were. I opened iTunes and sound came through the Soundsticks; I switched to the internal speaker and it worked there as well. When I tried the same with another embedded video, however, I only got sound from the internal speaker.
Has anyone had a similar problem or does anyone know how to fix this?

I had to plug in my Macbook Pro into a HDMI cable to watch something on a HD TV and had to switch some settings in the sound settings. Now when I plug in headphones and AUX cords the music still comes out of the internal speakers and the only option in the sounds settings for output are the internal speakers.

i have an intel macbook running leopard with the most recent update. A problem arose a day before the update was installed wherein my macbook no longer transmits sound through the headphone jack. i have no reason to suspect a hardware failure, there has been no damage to the computer. is there any way this could (please, god) be a software failure? and if so, one that i can fix?

I have dual diaplay's through HDMI, and use this to play dvd's. What I want to do is use the Macbook for other uses and have the sound comming through the macbook, wilst not affecting the sound from the movie being played through the HDMI out put. Currently in the settings for sound outup, all audio will either go through one of the options. How do I split the sound output per program.

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 (I know the earbuds are good). The external speakers are being recognized by the sound panel in system preferences.

I have a (little) problem with my new MacBook Air 2014 (13 inch.) running on 10.9.4 : when I connect it to any HDMI device (Philips monitor or Sony TV through Marantz amplifier) through a mini DP-HDMI adapter, I can't set audio output to HDMI because this option does not exist... However, I have video signal.Â
I've tried lots of "solutions", but nothing is working :
    - Shutting down, restarting, sleeping with and without the cable connected
    - Change HDMI cable
    - Reset PRAMÂ
Finally, I think the problem come from the Macbook because I have an other laptop (a Thinkpad with a mini displayport, with Ubuntu 14.04) and the video and sound are working normally.

My friend is looking into buying the new 27" iMac Core i7 to replace his PC desktop. The only thing holding him back is that he has an analog surround sound system he uses for his speakers. I am having a hard time myself finding a converter that can make his speakers work in the iMac's optical digital output port. Any products out there that will do that?

Hey, my macbook was getting rather slow so I decided to do a clean install of Leopard, but now I have absolutely no sound whatsoever apart from the startup chime! The volume keys now don't control volume and instead do expose and dashboard.
I did however install it with a Leopard disk that was from a shop and not one of the grey ones that came with the computer, is that the problem? If so how can I fix it?

I spent most of last night trying to get this done! No problems with the vision, cable between Macbook and HDMI input on the TV is fine. I have a 3.5mm Jack to Phono lead which I thought would work for the Audio. No sound. Maybe I'm not setting the Sony TV up properly, or I'm putting them in the wrong inputs (I've tried the all I think). There is a headphone (3.5mm) on the TV...but surely that's an output.

The output sound is suddenly really quiet. I have to turn it all the way up to hear anything all all sometimes. My iTunes seems fine and my notification sounds work, but playing videos is seriously sketchy (from YouTube, Hulu, Facebook, wherever).

The speakers on my Macbook have suddenly stopped working. If you plug headphones in, fine. In the system preferences, 'built in speakers' are no longer an option for audio output. Just 'digital out'. When I try and change the volume of the speakers, the symbol is greyed out, and there's a little "you can't do this" symbol.
I have a Macbook black 2.0ghz with 10.5.8
