Macbook Pro suddenly has no sound output. The menu for sound is greyed out. System preferences/sound doesn't alow me to set volume or mute.

how to find a way to change the input and output devices for sound without going into System Preference, and I finally got round to a little focussed googling and found this:

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.
View 1 Replies View RelatedI 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?
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!!!

this problem just started for me a couple days ago. I cannot tell what action causes it, but now restarting and resetting my PRAM settings does not fix it. I also tried a fix I read where I created a login item that resets the audio. I ALSO tried plugging in headphones. I am running OSX Lion 10.7.4.

The sound just went out on my macBook Pro. The volume icon is greyed out and is black when I plug in headphones, but those don't work either .

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 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.

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 lost my macbook speakers sound after instalation, there is grey icon and I can't control volume. Please let me know all possible ways to resolve problem. Btw,after reboot I heard sound when mac loads, and its working when I using headphones. When I start iTunes, and plug out head phones there is a red light. When I close iTunes red light disapears. But no sound at all.

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).

My sound has completely quit working. In the sound system prefs I get a massage saying "No output devices found". If I press the volums button keys the onscreen display comes up but has a 'no access' icon on it (a circle with a line through it). The icon in the toolbar has also vanished and there's just a blank space in its place.
Oddly whatever happened also seems to have effected my ability to view Flash movies -*the will play for a few seconds an then pause *they don't stutter they just pause. I think that whatever the issue is it was caused by a force shut down. All my applications were hanging so I had to press down the power button for a few seconds. Since then nothing!
This also effects the start-up sound which I don't get and all users of the machine are the same so it's not a case of deleting users prefs. So far I reinstalled the latest system using combo updater, run disk utility to repair disk/privileges (from start up disk) and zapped the PRAM.
I have a 13" 2010 MBP. When my headphones are plugged into the jack, and no sound is being outputted, the headphone jack seems to "turn off". If I want to do something that outputs a sound, like emptying the trash, there is a 3 second delay from when the trash is emptied to when the sound is played.
View 6 Replies View RelatedMy MacBook Pro seems stuck on digital output thus no sound from speakers. Headphones recognized and work but internal speakers don't revert to default or even show up as a sound option in System Preferences. Any way to get internal speakers back? Restarting computer did not do it.

All of the sudden the sound on my MacBook is no longer working. When I look at System Preferences>Sound>Output it says there are no devices found, even when I plug in external speakers.

I use studio monitors (speakers) with my macbook pro 13 (2010) and a samsung 1080p external display. Whenever I plug the display in, it causes a hum in the speakers, and weirdly the pitch of this hum varies depending on the brightness of the contents of my screen. I have borrowed my friends USB audio interface, and I still experience the same problem, except the hum is now cleaner and louder. I would assume this rules out problems with the internal sound card.
In both cases, the hum stops when the sound card/output 'goes to sleep' (ie after there has been no sound output for a few seconds). Also the hum only starts when the computer is outputting to the display. In the few seconds between physically plugging the display in, and the mac sending a signal to it, there is no hum. This is why I'm starting to think this may be a problem with the computer and not the monitor. The monitor is a cheap (£120) monitor - samsung p2270HD, and also has a TV tuner and stuff.
What I need to know is whether this is a problem with the computer, bleeding the signal through to the sound output, or whether it's my kind of crappy monitor. Another thing, might it help if I changed from VGA (analogue) to DVI (digital) video output?

I have the first generation of the silver macbook (with the black keyboard- before it went to macbook pro). I have been watching movies from my computer onto my TV via a HDMI cable. For a while now I have been trying to get the sound from my computer to go onto my TV, but I do not have the option of HDMI on my computer.

I had a first gen aluminum 13" Macbook that I spilled beer on. It was basically a write-off, but fortunately the HD was not damaged.I just got my 13" Macbook Pro today, and replaced the new HD with my old one. Everything is working fine, except that there is no sound.When I go to System->Sound I see "No Output devices found", and when I press the sound buttons on the keyboard, the speaker is grayed out.I know this is not a Hardware issue for a couple reasons. First, it properly 'chimes' on startup. Second, I did try running the computer with the new hard drive, and during the sound was working properly, volume adjustment buttons working, etc.

The Sound Settings show no output device. When trying to adjust the sound a circle with a line through it appears. Cannot run the volume adjusted up or down either. Also the sound does not work with a headset either. Have tried PRAM and SMC rest as well as plugging and unplugging headset. Running 10.9.3. Was running fine yesterday - feels like it may be hardware problem?
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?
View 2 Replies View RelatedUsing my Mac earlier today I lost all sound output, and attempted to reboot it to try and fix the problem. Now instead of booting it's stuck on the white loading screen. I've tried turning it off and on again from here, but I still get the same result.

however today suddenly the superdrive decided to make a 1-2 second 'seeking' sound at *every* startup. there is no dvd inserted nor have i used it even once in this week. it does this at the grey apple screen at the same time the apple "chime" sounds.
i am pretty sure it didn't to this up until today, i am not particularly concerned but why would it start doing this after a week on its own?
my sound suddenly stopped working after i unplugged my headphones, how do i fix this?
