MacBook Pro :: Volume Seems To Be Locked - No Sound Comes Out
Oct 30, 2009
The volume seems to be on lock and no sound comes out of the computer speakers. If I go to the volume sign at the top of the page the volume meter is white and stuck at the top. If I press F5 and F4 it moves neither up nor down and underneath the volume bar there is a circle with a line in it, which I presume is mute. I have gone into system pref -sound -out put and thats stuck too. Also there is a red light on in the headphone socket.

I'm trying to install iTunes 9.2.1 but I keep getting a pop-up saying: the destination folder iTunes 9.2.1 is on a locked volume. Please select another destination. I tried getting some help from Apple but couldn't afford their tech support, the only thing they could tell me is I need to look into system security and something about unlocking the computer?

Previous History: I'm on a MacPro and I have my main user account on another volume than my system. This has worked just beautifully for me over the past years, sometimes there are drawbacks and it's kind of more failure-prone in some cases. This 'some cases' now happened again: there was a blackout and after that I couldn't login to my user account on the non-system volume anymore. I've been there once and hadn't any problems fixing it somehow, but now I screwed up big time.

I have a late '08 MBP hooked up to a new 27" ACD, using a bluetooth apple keyboard and magic mouse. It's been working fine in all respects until I woke it up today. Everything is fine except the volume. If I tap volume up or down on the keyboard, there's serious latency (5-10 seconds) between me pressing the button and it showing the volume moving. Secondly (and more importantly), there's no sound at all (no matter what volume it's set at). I've already directed the sound through the monitor's speakers (like I said, everything was working just fine). I've tried rebooting, double-checking the sound settings, and disconnecting/reconnecting the bluetooth keyboard.

out of the blue something weird started happening. When i would press the up and down volume keys on the keyboard, no sound is coming out. When i raise or lower the volume from the top status bar, that little click is audible, but when i press the up and down keys from the keyboard, no sound comes out. is this a hardware problem? will apple replace/fix this? could i have muted it or something or is this like i said, a hardware problem?

The volume is muted, but I can't un-mute it because I am unable to click on any of the sound options because they are all "grayed out". The little box next to mute is checked and I cannot un-check it because it's grayed out. Nothing works when I plug in headphones or speakers or anything, and there is no red light glowing where you plug the headphones or speakers in.

With my new headphones (Sennheiser HD280-PRO) even the lowest volume is too high (even when using the extra levels using the option-key). It's just below the level where it'll be uncomfortable, but lower would still be preferred.
Does anyone know how I can get OS X to use a different scale? I have a MBP 4,1 with OS X 10.6.3.

So I've been following the MBP forum for their Audio Volume issues because we seem to have the same problem. Check out their issues here: [URL]
There is also an apple discussion here. [URL]
I have a Late 2008 MB running both Leopard and Boot Camp with Windows XP pro SP3. Under boot camp it uses the RealTek driver for the sound card. It is putting out very low volume. Many people have posted similar problems with Vista and windows 7.
Here's the test I did to confirm. I made a 1kHz test tone audio file and played it out of OS X. I connected the output of my headphone jack to a volt meter and measured a little over 1V or 1000mV. I switched to Windows and played the same file. This time I measured 280mV. This proves that the RealTek driver is not sufficient and does not measure up the full potential of the Macbook.
I've called apple on the issue and they say that it is not their problem and they do not support it. Even though they advertise that Windows is fully functional under boot camp. The solution for the MBP was that someone modified the INF driver file. Unfortunately, Apple uses a different chip in the MB and this solution will not work. I tried it.

Everyone knows that when you adjust the system volume of OS X you get a sound that says how loud or soft the sound is. My school is using a Mac to run the sound for the fall play and I need to disable this sound. I know it can be done, I read how in David Pouge's OS X Leopard: The Missing Manuel, but that's currently several miles away in south Philly at my sister's house.
Can anyone tell me how to disable that sound? I think it might be a Terminal command, but like I said, I can't remember and I can't check.

Anyone else have this happen to them - i.e. their preferred sound volume setting was not saved after 10.6.2 was installed? It's not a problem per se, because sound output still works normally, and the volume can easily be changed back, but still... it strikes me as odd.

I have a MacBook Air, and the sound is not working. The sound bar is full but there is a stop sign like the one when you completely turn off the sound. And I cannot control the sound bar, It is stuck like that.

OS X Lion, output: Cinema Display. Volume doesn't change by control keys on keyboard. But it does with software volume control (on iTunes, for example). When I press control buttons on keyboard, volume icon on display appears and changes - but not the volume. It lets me know that buttons are working, and Mac recognizes that.

since a few weeks, we regularly experience that the sound volume control does not show up in the screen title bar, and we cannot play music in iTunes or in youtube. I don't know if this is since i attached a usb Time machine backup disk or since when i upgraded from 10.7.2 to 10.7.3 The only way out is rebooting and then this works again, The sound volume control is back and i can listen music.Â

I have a Powerbook 1.5GHz 15.2" with mac os x 10.5.4 and yesterday while cleaning the computer I noticed something weird. With computer unplugged from the power source, i turned it on and increased the volume when the desktop come on. Before I could hear the alert sound when you change the volume there was another sound, like 3 lower volume pops, the normal sound it makes when you change the volume. Then I turned off the computer plugged in all the cables and power source and turned on and then when I changed the volume I only hear the normal alert sound when changing the volume. It only happened when the computer was running on battery.

I have spent a lot of time over the last two years trying to get my itunes library organized as well as getting good digitized versions from my vinyl records as well as CDs. I was pleased with my results and then I added the songs to itunes. I could not believe how inconsistent the sound quality was. Invariably the volume is always lower. [Do not post a reply such as: Check the volume controls in itunes proper as well as in itunes preferences (i.e., Sound Check, Sound Enhancer) & the Volume Adjustment in the Information pane under Options for particular songs.] I tried all of those means of adjusting volume. They do NOT work.Â
There is something more insidious at work in itunes which prevent good sound reproduction. I will give an example. I have played Frankie Valle and the Four Season's song "C'Mon Marianne" on the OS X system sound (i.e. clicking the play button to the song file when selected on the desktop or wherever it resides) as well as in Amadeus Pro. The song sounds great. When I play it when it's in the itunes' library the first part of the song is too lound and then when Frankie Valle starts singing his voice is at a significantly reduced volume.Â
I have edited the foregoing song in Amadeus Pro to a very high volume (i.e., Effects>Amplify), reloaded it into itunes and it still does not inprove the volume of Frankie's voice in the song, even though the rest of the song is somewhat louder. I have played with the Equalizer in itunes to no effect. It just does not work.Â
Now, I would glading move away from itunes and use another media player. However, I have other Apple devices through which I listen to music. And the only way I know of to listen,e.g., on the iphone is through itunes.Â
The other related problem with itune, or should I say iCloud, is icloud match. The icloud Match has taken great sounding music and given me back music of an inferior quality, even though it is a Matched AAC format.Â

I use an external hard drive for Time Machine backups and to store some larger video files in a folder called Videos. The Videos folder on the external drive is now locked and I can't unlock it. I go to Get Info, hit the lock icon and enter my password, but the "Locked" checkbox is greyed out in the General section. In the Sharing and Permissions section, instead of displaying my name, it says "Fetching . . ." and I can't change the Privilege from "Write Only".Â

I have a small issue on my iBook (G4) that's been driving me a bit crazy lately. I noticed a few months ago that when I selected a song/video on iTunes to play, I would get uneven volume output on my two internal speakers. I tried restarting iTunes, restarting the computer, etc. to no avail. In addition, sometimes this problem would not arise for a few days, and then suddenly start up again.
I then dug up the program Audio MIDI Setup and saw that the sliders were uneven . Once I slid them back together, I thought I had solved my problem. Nope! It came back, and I even saw that if I opened up Audio MIDI Setup right after the computer turned on, the sliders would be skewed even before opening iTunes or Safari or some other program that used audio.
I've come accustomed to manually balancing the volume output, but the irregularity of this problem occurring frustrates me. Attached is a screenshot of Audio MIDI Setup with the issue--note the Audio Output sliders.

I watched a video and it was very loud so I went to System Preferences and turned the sound down.But now I can't mute by clicking the F9 button as I normally can. I can mute by going to System Preferences but I don't want to do this.Before I changed the volume in System Preferences, the keyboard keys worked fine for volume adjustment. I could make it quieter, louder or mute.I have tried with checking and not checking the option to display volume on the screen (in System Preferences).

I can't seem to edit any pictures with Preview anymore since I upgraded to Lion. Every time I try to save an image after resizing or whatever, it says the file is locked. If I check the info of the file the "locked" checkmark is unchecked. And I have all the permissions to the file. Tried everything, switched the "lock after 2 weeks" thing of in Time Machine (even though tha would probably not help: images I took today are still "locked" in Preview), tried copying them and then saving them, and tried to lock them and then unlock them, but I can't seem to edit and save them.

Getting a message within photoshop that files cannot be saved as they are locked. I check the same files with 'Get Info' and the locked file box is unchecked. I have changed file permissions on the entire disc so that everyone can read/write but still the same message. Tried terminal command to uncheck flags also to no avail. I can do save as but a little frustrating. Is there a workaround to get all my files back onside?
This is a new disc that I may have installed without due care to permissions/ownership when I formatted it.

I have a Mac Pro and not too long ago I swapped from a fat, heavy and filthy white Apple Keyboard to a new skinny silver one. I like it, and also love that the F7-9 Skip Back-Pause/Play-Skip Forward keys work for iTunes, even when another app is active (what's the word I'm looking for - in focus or whatever). But I use Optical output, so the volume keys (F10-12) don't do anything. I know that, when iTunes is the active app, I can command-+/- to change the volume, but I'd love to be able to map the F10-12 keys to do that - without having to have iTunes active (playing, but not the active window).
