Software or hardware problem? I have no sound headphones/speakers

quick question-
Is it signifigant that I hear the startup chimes, but after its boots into OS. I cant hear any sound from either the speakers or headphones. I also tried Imic (usb audio input/output device) and didnt get any sound either.
I have deleted sound preference
I have zapped PRAM
thx

Have you checked sound preferences under System Preferences. Is the default output your speakers and default input microphone? I remember when i re-installed Panther on a Mac Mini that the default setting was none and i heard no sound nor could i input any.
Good Luck

  • [ Helix ] Rear camera picture malformed, but video is fine. Software or hardware problem?

    Hi, it's is my first post here, so  welcome everyone
    I've just purchased Helix 3702-3LO (i7, 8GB, 128GB, Win8Pro 64bits upgraded to 8.1) and today found some problem. Pictures taken by rear camera are malformed. The picture looks like:
    https://drive.google.com/file/d/0B5MpmFU1Jqq8Ym5ucGt6WDhUQXM/edit?usp=sharing
    But at the same time video taken by the camera is perfect. So how do you think, is it software or hardware problem?
    I've already tried refresh drivers, update what was possible to update, but still no imrovement, I still want avoid sending the computer to the service. It looks like some part of the image (bottom) is paste in the middle. Looks like codecs problem??? 
    But now I'm not sure if it is only software problem or may be some how hardware (video is recorded is fine).
    Thank you.

    Solved!
    Go to Solution.

    Thank you kroe, you were absolutely right!
    I rolled back the driver and it's fixed now, I should think about this in first place! :-)
    "Device manager" > "Imaging devices" > "AIT Webcam" > Right Mouse Button Menu > "Properties" > Tab "Driver" > "Roll back driver" > OK
    and now I have, like you wrote, "Integrated Rear Camera" instead of "AIT Webcam"
    And the photos are perfect now :-) Thx again.
    So.. problem SOLVED! Thx

    Open Console in Utilities & see if there are any clues or repeating messages when trying one of those Apps.

  • Upgrading from OSX 10.3.9 to 10.5.4, Software or Hardware problem?

    I have a Mac mini G4, 1.42GHz, 1GB ram, running 10.3.9 I tried to install 10.5.4 from the grey disk that came with my newer iMac but I just get an error saying it cannot be installed. Is this a hardware problem with my Mac mini or a software problem with the disk only being lisenced for one computer or something like that?

    Leopard requirements/10.5.x...
        *  Mac computer with an Intel, PowerPC G5, or PowerPC G4 (867MHz or faster) processor
    minimum system requirements
        * 512MB of memory (I say 1.5GB for PPC at least, 2-3GB minimum for IntelMacs)
        * DVD drive for installation
        * 9GB of available disk space (I say 30GB at least)

  • Brand new mac pro crashing. Software or hardware problem?

    Hi!
    First of all, I just wanna say - help from as many as possible would be highly appreciated, as I've talked to apple service center etc. No one knows what the problem is.
    Alright, here we go. I purchased a Mac Pro with 2x500GB HD, 4GB Ram and 2x2,66 Dual Core Intel Xeon processors just two weeks ago. Up until now, it has worked flawlessly.
    The first thing I did, was I imported my home folder from the .mac software Backup, and it worked fine. Everything was okay for a week or so.
    Then I used the application Visual Hub to convert some video files into iTunes, and it worked fine. Along with this, I downloaded stuff with Tomato Torrent - four or five downloads, couple of gigs, but not too much.
    And then the mystery started. I had the following applications open; Pages, Mail, Safari, iTunes, Visual Hub, Tomato Torrent and iCal. All of a sudden, iTunes crashed, saying it couldn't save the session or something, and my music library xml file got damaged. This happened quite a few times, and I had to re-import all the songs and movies and make new playlists.
    Pages said it couldn't save to disk, and Mail said the startdisk was full (it had over 350gb of free space).
    I forced a shutdown and when I restarted the machine, the blinking folder with a question mark showed up. I re-started it again, and it found the startdisk, and I got into MacOsx. However, no applications would open and if I tried to copy anything or empty the trash, the dialog box marked files as DW and NE instead of the file names.
    So I restarted from the install disc. It couldn't activate the main HD when I tried Disk Tools, and found lots of faults on the main HD that couldn't be repaired. After 5 or 6 restarts it finally found it, and I was able to re-install Mac OsX.
    After that, it seemed okay. Everything worked as it should, but the machine is working very slow, and when opening files and folders I sometimes get the wheel of death. It hangs in almost every application and when I try to move around a finder window for example, it jumps around in sharp movements instead of gliding.
    Disk tools can't find any problems on the harddrives anymore. Everything seems okay, but I feel that it's not.
    Apple says it might be the harddrive or the memory.
    I really do not want to send them the machine, cause I really depend on it. My question is - could this be a hardware or software problem?
    If it is a software problem, does anybody know what it can be?

    I agree that it might be the hard drive or memory.
    Run Apple Hardware Test.
    Get some backup drives going, and use Disk Warrior and SuperDuper.
    Did you import from a G4/5 computer some applications? don't. Install only.
    Were any of the drives or memory 3rd party or all Apple?
    When you installed the system again, did you erase? you should. And especially because it came up with errors and problems. You NEED 3rd party disk repair (Disk Warrior is the most reliable and preferred).
    It sounds like Visual Hub or Tomato threw a monkey wrench into the gears.
    And at this point your drive and file system needs to start all over, fresh, from scratch, and backup your data files, and then reformat.
    The only way to know is to physically test and do the things that a "mechanic" does, with more tools and experience with tools and problems.
    iTunes can push the limits and stress RAM, so it is a good way to find marginal or poor RAM. So is Memtest. But it takes awhile, but can be run 16 copies at once to test 256MB chunks for 4-5 cycles. No guarantee.
    Zero your drives. It helps insure they are working. Or put them in a PC or run XP/Vista on your Mac Pro and use vendor tools (LifeGuard, Seatools, etc) to map out blocks or zero the drive)
    It also ounds like the drive's permissions were trashed in the process and the ownership locked you out. Or something. WhatSize and OmniDiskSweeper and good. Or Tomato turned something on/off or into soup or sauce.
    Never continue to use a system after freezes and crashes without taking some precautions, maintenance, booting from an emergency 2nd drive.
    Use FSCK in single user mode.
    Do a Safe Boo.
    run Applejack to delete all the cache files along with any swap files (can't hurt, some don't see the need).
    Make a list, Rule something out and move on. But you will have to start with a freshly erased drive or partition, fresh OS, and then gradually test and add, one thing at a time.
    Lastly, when you do install the OS, and have made all the APPLE updates, make a backup.
    Create a disk image as well (sparse) on another drive/s. Setup one as "emergency only" and never add or alter or use it for anything other than running updates to Apple, disk repair stuff, testing the main drive.
    If you get to having a stable system, back it up as a clone of your working system. Put it away (Firewire is ideal).
    Updating to 10.4.11 or something ?
    backup first so you have a working copy. Only add or update programs AFTER you have a backup. Takes longer but you can 'fall back' and have a recovery plan.
    Installing an application that you are unsure of or might cause trouble? even an OS update can cause trouble, and there is no easy way yet on OS X to "back out" or uninstall or revert to an earlier point or driver or version. The only way I know of it with backups and more backups.
    Which is why I have JUST the OS on its own drive, just have to deal with applications and the system that way, and all the data and personal files are safe but also backed up.
    Rather than use online backup, get some backup disk drives.
    That may or should be "common sense" approach to installing and updating. Takes longer. Protects you and your data.
    When you had to re-import your data again and again, you were already walking on thin ice, about to go. Or had gone and just hadn't hit yet.

  • Software or hardware problem on MacBook Pro?

    I was listening to an audio podcast on iTunes (on my 2011 MBP) when sound began to stutter. I observed that when sound stopped, so did iTunes timer, so it was my computer and not the podcast. This kept getting worse, unitil the screen froze and I had to turn computer off manually (I was on AC power, not battery). When I turned it back on, I got a gray screen, then flashing question mark on gray screen. I used option-d on startup to do internet hardware test which said "no trouble found." However, I still only get gray screen or flashing question mark, so the next step would be to boot from DVD. I am reluctant to do that, because I am convinced there must be a problem with my hard drive for this to have occured the way it did. It is an hour and a half drive to the nearest Apple store. Any suggestions before I go there?

    Glad to hear you have your data backed up.
    The issue could have been developing over time from a bad ground in the wall outlet or if the computer got one too many zaps of static electricity or a good solid thump from dropping onto a table or going into a bag or case.  Digital information (which includes the formatting of the drive itself) is delicate despite efforts to make devices more durable.  You may have just witnessed the end of a long chain of events which resulted in this behavior.
    Or it could be a failed drive. 
    You should attempt to erase as if the erase fails that is conclusive evidence that there is something hardware related going on as all the symptoms you've described thus far could have a software root cause.
    When you take the computer into an Apple Authorized Service Provider (AASP) they will diagnose the issue to determine what hardware components are having an issue (assuming its hardware).  If you are in the US you can also call AppleCare, and as your computer is under warranty they can send you a box and the computer can be sent in for repair if you don't want to drive somewhere and leave it: https://expresslane.apple.com
    If the hard drive is actually failed and needs to be replaced, the failed drive goes back to Apple.  If you want to see the drive physically destroyed you would have to pay for the replacement drive they would be putting in your computer as they would be giving you an extra drive (The brand new one which is replacing the bad one and the bad one itself). Physically damaging the drive would not be ok as that violates the drive warranty which means Apple wouldn't be able to go back to the drive maker (Hitachi from what you reported) and say "Hey this drive you sold us failed. Reimburse us for it under it's warranty."
    If you have concerns about the data on the failed drive you could take a big magnet with you to the AASP and ask them to put the drive on the magnet when they take it out to replace it (I keep a rare earth magnet around for just this purpose).

  • Software or hardware problem, please help

    I have my MacBookPro(early 2008) 2,6 Ghz Intel duo. 4 Gb 15 inch, with all the updated software....It was getting slow, so I used the disk utility to check the and try to to solve problems I found this
    el archivo SUID “System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/MacOS/ARDAg ent” se ha modificado y no se reparará. (the archive has been modified and will not repaired.)
    I also run ONYX and have the same answer.
    After that finding the mac doesn´t start, no signals on the screen, the disk makes noise but nothing happens.....I find out that MBP, has a video card that after a few years stops working, because I found that message I am doubting of a Hardware (videocard) or a system problem , any help ?
    I just bought an imac to transfer all my work as I used that computer as a desktop.....but I wanted to recover the data and make it work to take it to work.....
    Any help will be great !
    I have an important presentation next january and I need to recover the data....

    Connect the Time Machine backup drive to the iMac. If you've never started up the new iMac, then when you do you will enter the Setup Assistant where you can opt to restore from a Time Machine backup. Just follow directions.
    If the iMac has already been through the Setup Assistant, then open Migration Assistant in the Utilities folder and use it to migrate from the Time Machine backup drive.
    A Basic Guide for Migrating to Intel-Macs
    The Knowledgebase article Intel-based Mac: Some migrated applications may need to be updated refers to methods of dealing with migrating from PowerPC chips to Intel with the Migration Assistant safely. The authors of this tip have not had a chance to verify this works in all instances, or that it avoids the 10.6.1 and earlier Guest Account bug that caused account information to get deleted upon use of the Migration/Setup Assistant. However, a well backed up source that includes at least two backups of all the data that are not connected to your machine will help you avoid potential issues, should they arise. In event it does not work, follow the steps below.
    If you are migrating a PowerPC system (G3, G4, or G5) to an Intel-Mac be careful what you migrate.  Keep in mind that some items that may get transferred will not work on Intel machines and may end up causing your computer's operating system to malfunction.
    Rosetta supports "software that runs on the PowerPC G3, G4, or G5 processor that are built for Mac OS X". This excludes the items that are not universal binaries or simply will not work in Rosetta:
      1. Classic Environment, and subsequently any Mac OS 9 or earlier applications
      2. Screensavers written for the PowerPC System Preference add-ons
      3. All Unsanity Haxies Browser and other plug-ins
      4. Contextual Menu Items
      5. Applications which specifically require the PowerPC G5 Kernel extensions
      6. Java applications with JNI (PowerPC) libraries
    See also What Can Be Translated by Rosetta.
    In addition to the above you could also have problems with migrated cache files and/or cache files containing code that is incompatible.
    If you migrate a user folder that contains any of these items, you may find that your Intel-Mac is malfunctioning. It would be wise to take care when migrating your systems from a PowerPC platform to an Intel-Mac platform to assure that you do not migrate these incompatible items.
    If you have problems with applications not working, then completely uninstall said application and reinstall it from scratch. Take great care with Java applications and Java-based Peer-to-Peer applications. Many Java apps will not work on Intel-Macs as they are currently compiled. As of this time Limewire, Cabos, and Acquisition are available as universal binaries. Do not install browser plug-ins such as Flash or Shockwave from downloaded installers unless they are universal binaries. The version of OS X installed on your Intel-Mac comes with special compatible versions of Flash and Shockwave plug-ins for use with your browser.
    The same problem will exist for any hardware drivers such as mouse software unless the drivers have been compiled as universal binaries. For third-party mice the current choices are USB Overdrive or SteerMouse. Contact the developer or manufacturer of your third-party mouse software to find out when a universal binary version will be available.
    Also be careful with some backup utilities and third-party disk repair utilities. Disk Warrior, TechTool Pro , SuperDuper , and Drive Genius  work properly on Intel-Macs with Leopard.  The same caution may apply to the many "maintenance" utilities that have not yet been converted to universal binaries.  Leopard Cache Cleaner, Onyx, TinkerTool System, and Cocktail are now compatible with Leopard.
    Before migrating or installing software on your Intel-Mac check MacFixit's Rosetta Compatibility Index.
    Additional links that will be helpful to new Intel-Mac users:

      2. Apple Guide to Universal Applications
      3. MacInTouch List of Compatible Universal Binaries

      6. Transferring data with Setup Assistant - Migration Assistant FAQ
      7. OS X Lion: How to use Migration Assistant to transfer files from another Mac
    Because Migration Assistant isn't the ideal way to migrate from PowerPC to Intel Macs, using Target Disk Mode, copying the critical contents to CD and DVD, an external hard drive, or networking will work better when moving from PowerPC to Intel Macs.  The initial section below discusses Target Disk Mode.  It is then followed by a section which discusses networking with Macs that lack Firewire.
    If both computers support the use of Firewire then you can use the following instructions:
      1. Repair the hard drive and permissions using Disk Utility.
      2. Backup your data.  This is vitally important in case you make a mistake
          or there's some other problem.
      3. Connect a Firewire cable between your old Mac and your new Intel Mac.
      4. Startup your old Mac in Transferring files between two computers using FireWire.
      5. Startup your new Mac for the first time, go through the setup and
           registration screens, but do NOT migrate data over. Get to your
           desktop on the new Mac without migrating any new data over.
    If you are not able to use a Firewire connection (for example you have a Late 2008 MacBook that only supports USB:)
    1. Set up a local home network: Creating a small Ethernet Network.
    2. If you have a MacBook Air or Late 2008 MacBook see the following:
      a. MacBook (13-inch, Aluminum, Late 2008) and MacBook Pro (15-inch,

    Copy the following items from your old Mac to the new Mac:
    In your /Home/ folder: Documents, Movies, Music, Pictures, and Sites folders.
    In your /Home/Library/ folder:
    /Home/Library/Application Support/AddressBook (copy the whole folder) /Home/Library/Application Support/iCal (copy the whole folder)
    Also in /Home/Library/Application Support (copy whatever else you need including folders for any third-party applications)
    /Home/Library/Keychains (copy the whole folder) /Home/Library/Mail (copy the whole folder) /Home/Library/Preferences/ (copy the whole folder) /Home /Library/Calendars (copy the whole folder) /Home /Library/iTunes (copy the whole folder) /Home /Library/Safari (copy the whole folder)
    If you want cookies:
    /Home/Library/Cookies/Cookies.plist /Home/Library/Application Support/WebFoundation/HTTPCookies.plist
    For Entourage users:
    Entourage is in /Home/Documents/Microsoft User Data Also in /Home/Library/Preferences/Microsoft.
    Credit goes to Macjack for this information.
    If you need to transfer data for other applications please ask the vendor or ask in the  Discussions where specific applications store their data.
    5. Once you have transferred what you need restart the new Mac and test to make sure the contents are there for each of the applications.

  • HT1600 After updating my Apple TV software this morning, I now have no sound. It is hooked up to play through my television speakers. Any ideas on how to get sound back? It was working fine before the update.

    I have tried re-booting Apple TV as well as the television, etc.

    Have you tried adjusting the "Audio Out" and the "Dolby Digital" settings in settings > audio and video? It may be worth trying several combinations of these settings, although typically it is the "Dolby Digital" setting that causes most problems for users.
    Also make sure that you have correctly mapped the input port on your sound system to the output, if you are unsure about how to do this, refer to the manual that came with your sound system.
    Have you tried playing various content sources (i.e. podcasts, music, iTunes Store video, other video etc), do you have the same problem with all types of content? If you use optical you might also check that you can see a red light at the end of your optical audio cable. Is your optical audio cable plugged straight into your sound system, or does it go through a switch or other device?

  • IPhone 5 showing no network when auto selected for carrier, select manually signal ok, software of hardware problem?

    Hi,
    I have a iPhone 5, since day one I have had poor reception, 1 bar, when my daughters Samsung S3 has 3 bars, same network btw. It makes me feel I bought the wrong phone.  If one more person at Three or Apple tell me to restore my phone to factory settings, I am going to scream. Also when network is selected as auto, the phone, when it feels like it goes to no service.  It is only when I select the network manually, does it get a signal.
    The phone is still under Apple's 90 day support, I was reminded today by a Apple rep of this. After the 90 days I would have to buy Applecare for any software related problem.  So basically if Apple do not ressolve the problem with my "not fit for purpose phone" within the 90 days, I will have to pay for it. This is not good customer service Apple, I am someone who has believed in your productsas I have an iMac and iPad. I waited years to get an iPhone because I had the 3GS, which I thought was crap, the iPhone 5 convinced me to give the iPnone another try, I have had nothing but problems with it, previous phone was a Samsung Galaxy Note, no problems at all.
    Has any one else had this problem with the iPhone 5?, I thought it might be Apple's dreaded aerial problem that caused so many problems on the iPhone 4.
    I would be grateful for some suggestions, I have already been advised to use it as an expensive doorstop, not funny.
    Many thanks.

    Well I had the exact same problem with my Iphone 5s, I tried many things such as turning the airplane mode on/off, restarting the device and also did a network settings reset. Nothing helped.
    The next thing I did was to do a general reset via iTunes to factory settings (Made a backup first. Very important if you can connect to iTunes, it's a MUST). When the phone booted-up again, I had to ''activate the phone. But to activate it, I needed a connection with a network. But that was the whole problem so I was stuck and couldn't do anything with the device.
    So I called the Apple support centre. We tried a few things, they all dindn't work. The last option (which worked for me) was to do a recovery (I have no idea what this reset is called)  via the device+ iTunes.
    To perform the reset, please follow these steps and hopefully it will work for you as well.
    1. Open iTunes
    2. Connect your USB cable to the computer, NOT to your device yet.
    3. Power Off your device, and be sure that it is Off.
    4. Press the home and hold it.
    5. Connect the USB cable to your phone. You will see a iTunes logo on your device, you can release the home button.
    6. Do a recovery via iTunes. iTunes will now recover the phone.
    If it doesn't work the first time, try again. I had to do it twice and luckily it worked the second time.
    I hope that this will help, Good luck!

  • Software or hardware problem?

    Hello Apple Community,
    quite recently I bought a new 13 inch aluminium Macbook 2.4 GHz. Great machine... however I have problems with standby-mode. Everytime I close the lid my MB goes directly to hibernation mode as everytime I re-open the lid the white screen with the loading bar at the bottom appears. Sometimes it doesn't turn on at all. The little white lamp which pulsates during standby turns off and the screen stays black. Sometimes it turns out that a kernel panic has occured.
    I tried to reset NVRAM, PRAM and SMC but nothing really worked. I know that the reseller who sold the MB to me has upgraded the RAM to 4 GB. Maybe he used incompatible RAM... Can this be a reason for my problems? Or maybe even a logical board failure? Or is it probably only a software problem?

    Hi GerV8,
    The white screen with loading bar is the unit's way of restoring OS functionality from "safe sleep." When the unit sleeps it stores all of the current running processes and applications to RAM, the safe sleep functionality shifts the RAM memory allocation to the HD in the event of power loss to the system.
    If every time you go to sleep the unit, even for a few minutes, it's converting to safe sleep then somehow the RAM is automatically writing the saved content to the HD versus keeping it for itself.
    If you've already tried resetting the PRAM & SMC, the next thing you might want to try is the RAM. Are you near the reseller who sold you the unit? Do you have the original RAM that came with the computer? I'd definitely be inclined to have you troubleshoot the RAM as the next course of action.

  • Do you have pop sound from speakers in Leopard ?

    hi,
    after using my macbook pro for 5 days, that known pop sound started to appear from my left speaker. I have read posts people experiencing this issue under Tiger but is it still there in Leopard ? and is this a hardware or software problem ?
    tks

    I'm sorry that I'm not posting an answer for you, but I'm posting to say I had this happen to my MacBook Pro today. I upgraded to 10.5.4 about a week ago and this came out of nowhere today. I accessed a web site that had sound, so I know I had sound earlier today. A while later I heard a pop from the computer. Then about a half-hour later, I realized I wasn't hearing sound any longer. I hit the volume up/down keys and saw the visual clue that the sound level was changing, but there wasn't the usual beep to confirm the volume level. I pressed the mute key and heard the pop again. Every time I pressed mute, I heard the pop. There was no sound otherwise.
    I confirmed that I could still hear sound through the headset output and shortly after that, the speakers started working again. I haven't had another problem since then. I wonder if plugging in headphones and unplugging them reset whatever was going wrong with the internal speakers?
    Regardless, I hope someone posts a definitive answer soon.

  • N95 problem - Software or Hardware?

    Hi, my n95 gone nuts these few days, after i installed a chinese supported firmware for it, my n95 have this constant lagging problem and have to take out the battery to shut it down, and have to wait for a while for it to "cool down" approx 10-15 min or else it cant boot up, just show a blank black screen, even it DID boot up, playing mp3 can lag up the phone too, so before i am going to the Nokia care centre, anyone kind enough to elobrate whether it is SOFTWARE or HARDWARE problem thanks, i was hoping it was software problem so that its easier to fix

    " after i installed a chinese supported firmware for it,"
    If you didn't have Chinese and you did something that's not allowed you may have void the warranty.

  • Is the on/off button bad function a hardware problem? What can I do if a mobile company don't fix this? Besides, my phone still have the apple warranty

    Hello everyone, I bought an iPhone 5 six months ago from a mobile company. now the on/off button is not working properly. I send it to this company technical service support and they didn’t fix it saying that the button problems are not covered by the warranty; moreover they say that warranty just covers software and hardware problems. First, is the on/off button bad function a hardware problem? What can I do if a mobile company don’t fix this? Besides, my phone still have the apple warranty
