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.
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?
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.
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 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.
My 1 yr old mac book pro is having problems with the sound after an update to the lion software last night. The sound preference is not showing any out or in device. But, the startup chime works
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've upgraded my old MacBook (MacBook1,1/Early 2006) with a new SSD, 2GB RAM and a fresh installation of Snow Leopard (Retail). Everything runs much smoother now, except that there is no more sound (no sound device found). I don't think it's a hardware problem, since the startup sound (chime) still works perfectly. Everything worked fine with OS X 10.4. I tried a SMC and PRAM reset, but didn't help. Some results on Google said that I should try to stick in some headphones and that should do the trick, but it didn't.
I have a macbook pro and the audio on it the other day was perfect. Now i cant get it to work. It wont let me un mute it and under system preferences it says that no output devices are available.
I have a problem about sound. It's no output or input device when I install parallel desktop 7. Is there any way that can solve this issue without uninstalling Parallel Desktop?
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?
After upgrading to Lion (10.7.3) it started this anoying beep sound that is almost unbearable. Also, I upgraded to Lion so that my Mac could run faster, but I am more disappointed now!
Occasionally after booting back into OS X from bootcamp (windows 7 home premium), I will not have any audio output devices. If I restart OS X again they return, anyone have what maybe happening here? This is on a 09 MP...
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.
so heres what happend. my macbook has been acting strange. freezing and sound not working at times. system preferemces quitting etc. and i just got it back from its thrid repair. THREE REPAIRS IN LESS THAN 3 MONTHS> so i was downloading a game for my psp when i went to go get a bagel in the kitchen. i left for no less than a minute and when i came back the screen was black. i thought it just dimmed itself but no. i moved the trackpad clicked on all buttons click the mouse button everything. i noticed the light wasnt throbbing so im sure it wasnt sleeping. the light was just pure white(the sleep light) so i waited like 3 minutes than shut it down. do u know whats happening. i know now i will be getting it replaced but until then im trying to keep it working well enough that i can watch a ********** vid on youtube.
All of a sudden my mini's sound output stopped working and now doesn't recognize any output devices. worked earlier today not now, didn't add anything. system pref - sound - output = "no output devices found
Just today I have installed an application which was to do with sound switching , called "soundflower" once iv installed and run it there was an option "create multiple sound switch" did chose and start to creating a multiple, as soon as it started my sound card panel display as "no sound card founded" and my sound icon on the top bar turned to light gray.
Double click on that and when it opens you will see your hard drive (usually Macintosh HD) on the left. Highlight your hard drive and click on Verify Disk on the far right. If that is OK click on Repair Permissions on the left. If Verify Disk is not OK try to Repair. If Repair is successful then Repair Permissions if it is not successful let me know. But problem still remains.
I frequently have to switch my sound output device from Line Out to Headphones. I know all about the Option-Click of the menubar icon, but what I really want is to assign a hotkey to cycle through them (similar to the alt tab program scroll) when I can't easily get up to cross the room for my mouse.
If it helps I use a Logitech DiNovo Mac edition keyboard. I've looked all through it's prefpane but it doesn't have an option to switch sound outputs. If there was an unknown keyboard shortcut to switch outputs then I could easily just assign it to an Fx key.
On my 2009 I've noticed now that after using bootcamp for a bit then booting back into os x that i have no sound available, there's no sound devices in preferences. This is using the line-out jack.
I have been searching the internet high and low over the last couple of days to try and find some sort of device to attach my new 5.1 surround sound to my MBP 13". The speakers have front, rear and center/subwoofer inputs, which are 3.5mm jacks. At the moment all i can get is the subwoofer and 2 other speakers working at once. I understand that some of the content of my laptop wont be in 5.1 surround sound, but I'd still like that to be played through all of the speakers not just 2. So basically here's a list of the features I really want:
*Firewire or USB connection *Output to my speakers *Possibly an audio input for a guitar (not very important) *The ability to play stereo in all of my speakers Do I need to change/download anything on my mac to be able to output 5.1 in for example a DVD that I am playing etc?
I have Mac Pro with Digidesign/ProTools interface connected. I sometimes switch sound output from MP to run through the digidesign hardware. I'm getting message right now saying "selected device has no output controls", not allowing me to switch. I rebooted with the interface already turned on. I've run into theis before- can't figure out what causes this to happen. Sometimes it's OK. ?
I am new to macs and recently purchased an imac. My problem is when I connect a usb device such as my iphone or camera there is no sound played signifying that it is connected. I am used to using windows where a noticeable tune it played everytime a device is connected or disconnected. I have tried looking in setting and such without much luck. Is there anywhere else that can turn this feature on??
When surfing the net (like right now) or just letting it idle, my hard drive makes a slight "clunk" sound like the HD arm is hitting the edge of the case (or maybe starting up and shutting down?). There seems to be no loss of performance. I did a disk verify and everything is OK. Should I be concerned?
