OS updated - Sounds stops working

I updated my 2013 (Late model 2012) Mac Mini to the most recent version of the OS Mountain Lion this past weekend - now after about a day of use - the sounds stops working.  It is connected via the Thunderport to Displayport on a Dell Monitor.  Has always worked fine until the software update this past weekend.  Once I reboot - it starts working again and then a day later stops working and I have to reboot!  Any thoughts!
Thanks as this seems directly related to the upgrade!

Please read this whole message before doing anything.
I've tested these instructions only with the Safari web browser. If you use another browser, they may not work as described.
This procedure is a diagnostic test. It won’t solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
Third-party system modifications are a common cause of usability problems. By a “system modification,” I mean software that affects the operation of other software — potentially for the worse. The following procedure will help identify which such modifications you've installed. Don’t be alarmed by the complexity of these instructions — they’re easy to carry out and won’t change anything on your Mac. 
These steps are to be taken while booted in “normal” mode, not in safe mode. If you’re now running in safe mode, reboot as usual before continuing. 
Below are instructions to enter some UNIX shell commands. The commands are harmless, but they must be entered exactly as given in order to work. If you have doubts about the safety of the procedure suggested here, search this site for other discussions in which it’s been followed without any report of ill effects. 
Some of the commands will line-wrap or scroll in your browser, but each one is really just a single line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, and you can then copy it. The headings “Step 1” and so on are not part of the commands. 
Note: If you have more than one user account, Step 2 must be taken as an administrator. Ordinarily that would be the user created automatically when you booted the system for the first time. The other steps should be taken as the user who has the problem, if different. Most personal Macs have only one user, and in that case this paragraph doesn’t apply. 
Launch the Terminal application in any of the following ways: 
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.) 
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens. 
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid. 
When you launch Terminal, a text window will open with a line already in it, ending either in a dollar sign (“$”) or a percent sign (“%”). If you get the percent sign, enter “sh” and press return. You should then get a new line ending in a dollar sign. 
Step 1 
Triple-click the line of text below on this page to select it:
kextstat -kl | awk '!/com\.apple/{printf "%s %s\n", $6, $7}' | open -ef 
Copy the selected text to the Clipboard by pressing the key combination command-C. Then click anywhere in the Terminal window and paste (command-V). A TextEdit window will open with the output of the command. If the command produced no output, the window will be empty. Post the contents of the TextEdit window (not the Terminal window), if any — the text, please, not a screenshot. You can then close the TextEdit window. The title of the window doesn't matter, and you don't need to post that. No typing is involved in this step.
Step 2 
Repeat with this line:
{ sudo launchctl list | sed 1d | awk '!/0x|com\.(apple|openssh|vix\.cron)|org\.(amav|apac|cups|isc|ntp|postf|x)/{print $3}'; echo; sudo defaults read com.apple.loginwindow LoginHook; echo; sudo crontab -l; } 2> /dev/null | open -ef 
This time you'll be prompted for your login password, which you do have to type. Nothing will be displayed when you type it. Type it carefully and then press return. You may get a one-time warning to be careful. Heed that warning, but don't post it. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator. 
Note: If you don’t have a login password, you’ll need to set one before taking this step. If that’s not possible, skip to the next step. 
Step 3
{ launchctl list | sed 1d | awk '!/0x|com\.apple|org\.(x|openbsd)/{print $3}'; echo; crontab -l 2> /dev/null; } | open -ef 
Step 4
ls -A /e*/{cr,la,mach}* {,/}Lib*/{Ad,Compon,Ex,Fram,In,Keyb,La,Mail/Bu,P*P,Priv,Qu,Scripti,Servi,Spo,Sta}* L*/Fonts .la* 2> /dev/null | open -ef  
Important: If you formerly synchronized with a MobileMe account, your me.com email address may appear in the output of the above command. If so, anonymize it before posting. 
Step 5
osascript -e 'tell application "System Events" to get name of login items' | open -ef 
Remember, steps 1-5 are all copy-and-paste — no typing, except your password. Also remember to post the output. 
You can then quit Terminal.

  • After Service Pack 2 update sound stopped working

    Recently started again with my Satellite laptop. All was good and everything worked perfectly until i download Service pack 2. Ever since doing that the audio has stopped working.
    I'm a bit novice but have tried the following:
    I uninstalled the driver and downloaded the appropriate drivers from the Realtek website. reinstalled but still get the same problem. no error messages but just "Driver is enabled but has not been started" in the properties screen for the sound and device properties.
    Can anyone offer a solution?

    Hi
    Youre right. I have read that on some notebooks the sound doesnt work after XP SP2 installation.
    But the update instillation should help.
    Could you please post you notebook name?

  • I updated my ipad and the sound stopped working.

    I updated my ipad to IOS 8.1.and the sound stopped working. My sidebar buttons say soundeffects or soundeffects mute when I press them. On my control panel there is no sound bar. As you can see in this screenshot it is not showing a sound bar to adjust volume. HELP?!

    Update: Last night, I cleaned my headphone port & docking port. Reset Network Settings & General Reset all settings & reset ipad. Didn't work immediately & had some setbacks. I decided to wait to do the restore factory default for the next day, this morning. I decided to test the sound before proceeding. My sound is working correctly now & didn't need to resort to the restore factory default. All of the above worked but perhaps needed over night to really dry the rubbing alcohol used to clean the ports.?
    sound is working. Thanks so much for your help Diavonex!

  • Iphone sound stopped working after ios 6.0 update

    My 4s was working fine until I updated to 6.0.  After that, my sound stopped working.  If I plug in headphones it works, but as soon as I unplug it stops.  When I plug into my USB sync cable it works, but when I unplug it stops working. I updated through user settings over wifi and not through itunes sync if that makes any difference.  I know other people are experiencing similar problems.  Any help would be appreciated.

    Yes rev, I tried the dock cleaning as well, I didn't help me either. I read and tried everything others did-no luck. I'm guessing these are the facts, either it will quietly get fixed on an update or the % of phones with the problem compared to those that don't doesn't warrant attention and is better addressed through Apple by just replacing it..if it's still under warranty.

  • My iPhone 5s sounds stop working.i did not do anything it just stop working when I tried to turn on my music player all the sounds is not working I already check the volume and it is not also muted :( what happened can anyone solve my prob

    Hello everyone my iPhone 5s sounds stop working.i did not do anything it just stop working when I tried to turn on my music player all the sounds is not working I already check the volume and it is not also muted :( what happened can anyone solve my problem please

    Hey Kirby17,
    Thanks for using Apple Support Communities.
    If you are not getting any sound from the speaker, follow this article.
    iPhone: No sound or distorted sound from speaker
    http://support.apple.com/kb/ts5180
    Ensure that there is nothing plugged in to the headset jack or the dock connector.
    If the iPhone is in a protective case, make sure that the speaker port isn't blocked by the case.
    Make sure that the speaker and dock port aren't clogged with debris. If necessary, clean it with a clean, small, dry, soft-bristled brush. Carefully and gently brush away any debris.
    If an audio issue occurs when using a specific application, try testing other applications to see if the issue persists.
    If the iPhone is paired with a Bluetooth headset or car kit:
    Try turning off Bluetooth.
    If you experience difficulties with the Bluetooth feature, follow these troubleshooting steps.
    Restart the iPhone.
    If restarting doesn't fix the issue, ensure that your iPhone is updated to the latest version of iOS.
    If the issue is not resolved, please contact Apple Support.
    Have a nice day,
    Mario

  • The sound stopped working on Mac Book Pro OS X?

    The sound stopped working. Firefox installed updates and since, the sound is disactivated. I went to preference, and the silence box is checked, but it doesn't allow me to uncheck it. The sound peripheric is not recognised it seems. What can I do?

    Hopefully one of these steps should solve the problem.
    1. System Preference > Sound > Output > Internal Speakers
        Make sure Mute is not enabled.
    2. Remove the headphone.
        If you see red light in the headphone port, plug the headphone
        in and out of the port 5 or 6 times to flip the microswitch inside.
        Sound output may be stuck in the digital mode.
    3. Reset PRAM.  http://support.apple.com/kb/PH4405
    4. Reset SMC.     http://support.apple.com/kb/HT3964
        Choose the method for:
        "Resetting SMC on portables with a battery you should not remove on your own".
    5. Applications > Utilities > Audio MIDI Setup
        Audio Devices window
        Side Bar
        Click the Built-in Output.
        Under Mute any of the boxes checked? If so uncheck it.
        Option click the speaker icon, if present and select Internal Speakers.
    6. Launch iTunes and play a song. Adjust the volume there.
    Best.

  • Macbook Pro sound stopped working

    I was listening to music off of iTunes and my sound stopped working all of a sudden. I have restarted the computer and installed all new updates. When I go to system preferences for sound, the built in speakers do not show up. I tried putting in earphones and that works. Can anyone help me fix this problem? I have only had this laptop for a few months and I barely ever move it around...

  • Sound stops working until i restart.

    I currently have the satellite a505-s6965. I bought it back in 2009 but last year my hard drive crashed so I replaced it with a 1tb SSdrive and upgraded to windows 7 in the process. I havent had any other issues until maybe about 2-3 weeks ago when i noticed after so long my sound stops working. I can't play videos, music or anything. Itunes wont even show the song playing at all.  I have done everything, my drivers are all up to date, my bios is updated. I have tried headphones and none of that changes anything.
    However...if I hit the volume up button on the laptop, it will beep through both the speakers and headphones but no other sounds will play. But if I restart it will all go back to working forr so long. Sometimes when the sound works i may sound a little cracked or weird.
    Any suggestions on a fix for this issue?

    Hi. I see that this question has gone unresolved since Oct. I'm having a similar problem. Also using FCP 7.
    I have a video, recorded on a Canon Vixia HV30. I captured the video and found that the sound was recorded too high. There was an audio recorder, Zoom H4, recording at the same time, and it had a much better level, so I imported the .wav file to my project. I spent about 2 hrs cutting the video and the audio, syncing the audio to the video and making cuts between the songs that were played to edit out the between song banter and other stuff.
    All seemed to be working fine, and then at some point, I clicked the "L" key to move forward, and there was a loud pop, and the sound went away. Whenever I press the start key, or one of the J, K, L keys, it click/pops and no sound is available.
    Any help with that?

  • Sound stops working, 3 seconds after plugging in headphones

    I have a strange issue on my phone where the sound stops working after about 3 seconds (consistently), after plugging in headphones.
    I have the latest software update and I don't have any special sound modifying apps. No software I've installed ruined this, it has worked fine before, until about two weeks ago. I've also dust-cleaned the headphone jack.
    Without headphones, the sound works great.
    Here's an example of what happens
    1. I start a video on YouTube / play a song / start a call with someone / start a game
    2. The sound works well, nothing is strange at all
    3. I plug in my headphones
    4. The sound now works in the headphones
    5. About 3 seconds later, the sound stops working completely, in all the cases above
    6. The sound never returns, until I unplug my headphones
    I'm clueless as to what could be causing this. Does anyone have any idea?

    I've tried that, but it doesn't work
    It seems like a software/firmware issue, since the 3 seconds of working is 100% the same every time

  • My sound stopped working on my HP dv6-1280us

    Its only a couple of months old but my sound stopped working.  I don't know much about laptops but here is what I do know.
    It stopped working around 10 days ago.  At first there was no sound but I could move the volume up and down with the quicklaunch pad and the mute button would go from red to blue when touched.  I checked to make sure nothing was muted and everything seemed to be fine.
    I googled the problem and it said to do a system restoration back before it stopped working.  I tried several times and it went through the process but then when it rebooted it said that it didn't work and that none of the settings have worked.
    Then a couple of hours ago I noticed the mute button is now red and won't change to blue the volume slider is not responding to touch either.
    Then I saw a post on here that said to go to system recovery and reinstall the sound drived (IDT High Definition CODEC) and I did and it said it did but it didn't fix the problem.
    I am lost and would love some help if anyone has any ideas?  please?
    Thanks

    I got some help from a friend and her advice worked.  I thought I would post this for others having trouble
    Well I guess you could try this it would not hurt. Assuming you use Windows that is.
    Go to run and type services.msc when the box pops up scroll down to Windows Audio and double click. Make sure that the service is started.

  • Updates suddenly stopped working?

    I obtained my Photoshop from a school a couple or few years back. I believe they claimed the serial would work forever.
    But the updates just stopped working. They all download fine in the Adobe Application Updates Manager but when it goes to install, I get an error message:
    "Some updates failed to install.
    The following updates were unable to install. If you wish to install these updates, please fix the problems below and retry:
      Adobe Bridge CS5 4.0.5 Update
      There was an error downloading this update. Please quit and try again later.
      Photoshop 12.0.4 update for Photoshop CS5
      There was an error downloading this update. Please quit and try again later.
      Photoshop Camera Raw 6.7 Update
      There was an error downloading this update. Please quit and try again later.
    Contact Customer Support for further assistance."
    When I click the Customer Support link, I'm taken to a webpage that says:
    Error "This serial number is not for a qualifying product" | CS6, CS5.5, CS5
    Adobe upgrades and upsells require a qualifying previous product. If the upgrade or upsell installer can't find a previous product on your computer, it asks you to enter the serial number of a qualifying product.
    Try the solutions in this document if you receive the error “This serial number is not for a qualifying product. Please try another” when you enter a serial number in the Serial Number Upgrade screen.
    Can't find your serial number? See Find a serial number. "
    Yet in Adobe Photoshop, under help menu, there is still an option to 'Deactivate', so I assume the serial is still fine. (I hope I would be notified if my serial expired.)
    I'd really like to update my products.
    Please help.

    I updated manually using downloads from the website and it worked fine, but that still sucks I hope I don't have to do it manually every time.

    after an update safari stopped working any ideas on how to fix this?

    Use another browser to install Safari again.
    You can download Firefox for the Mac, place the download on a USB thumb drive stick it into the Mac and copy it, run the installer.
    Once FF is on, download a new copy of Safari from Apple's site.
