The sound on my macbook air isn't working how can i fix this

i was on line and i went to watch a video and the sound wasnt working and it still wont work everything is on but its not working out

Welcome to Apple Discussions
Some times simply quitting any and all sound Apps (iTunes, QuickTime, any audio player) restarting often solves the problem.  An SMC reset might also work.
If the laptop went to sleep with headphones or external speakers plugged into the headphone jack loss of audio on wake can result. In future do not sleep with headphones or speakers attached.

  • I purchased the multi-user iworks and recently had to replace my white imac's hard drive but didn't pay to fix the CD drive.  My iworks does not have a serial number on the box and now that my CD drive isn't working how can I reinstall this software?

    I purchased the multi-user iworks (yes back when it was new, 2009 or 2010 and recently had to replace my white imac's hard drive (but didn't pay to fix the CD drive).  My iworks does not have a serial number on the box and now that my CD drive isn't working how can I reinstall this software?

    Buy or borrow an external USB optical drive.
    See the confirmation email or covering letter to obtain the serial number. If you have lost it, contact the supplier.

  • The sound effects on my apps have quit. How do I fix this?

    The sound effects on my apps have quit. How do I fix this?

    If you lose sounds for keyboard clicks, games or other apps, email notifications and other notifications, system sounds have been muted.
    System sounds can be muted and controlled two different ways. The screen lock rotation can be controlled in the same manner as well.
    Settings>General>Use Side Switch to: Mute System sounds. If this option is selected, the switch on the side of the iPad above the volume rocker will mute system sounds.
    If you choose Lock Screen Rotation, then the switch locks the screen. If the screen is locked, you will see a lock icon in the upper right corner next to the battery indicator gauge.
    If you have the side switch set to lock screen rotation then the system sound control is in the task bar. Double tap the home button and in the task bar at the bottom, swipe all the way to the right. The speaker icon is all the way to the left. Tap on it and system sounds will return.
    If you have the side switch set to mute system sounds, then the screen lock rotation can be accessed via the task bar in the same manner as described above.
    This support article from Apple explains how the side switch works.

    Restart Mac and try again.  If you are still having trouble, see Apple's http://support.apple.com/kb/HT2090
    (Over time, Apple has changed the built-in camera's name on newer Macs from "iSight" to "FaceTime" and then to "FaceTime HD."  Regardless of the name of your Mac's built-in camera, the same info and troubleshooting applies.)

    I added photos of our company's products to the Goods App for our sales team to use as an electronic catalog.  Some of the pictures display perfectly.  Others are blury.  How can I fix this? I Googled pixel size for Ipads and checked this size against the blury photos.  They seem to be less than the max pixels allowed.  Must be another solution????

    Ged,
    whilst generally I agree with you a question (or two) for clarification so we can be sure we're not comparing apples with oranges
    I'm not familiar with O2's product lineup but given you're on Annex M is that a business package?
    Are you on an Infinity residential or business package?
    On the subject of the offshore support teams my experience from the other sife of the fence is that many, many of them are very technically orientated. The problem is that the ISPs they work for don't give them access to many of the tools that are needed (they need to raise internal requests to even get line checks done in some cases) and also they are very heavily scripted & monitored in what they do/say on a call.
    Sounds like O2 are operating as a contact centre rather than as a call centre which is much more preferable from the customers point of view.
    DISCLAIMER: although I work in the industry I do not work for BT and any opinions given are purely my own.

    It takes two to tango, maybe it's your recipient that has weak Internet/Cellular connections.

  • I have music that is playing within the iTunes program, but not on my iPod. How can I fix this?

    I have music that is playing within the iTunes program, but not on my iPod. How can I fix this?

    Skipping songs
    The iPod seems to fail to play all of the occasional track that iTunes, and indeed other PMPs, are happy to play. There is probably some minor technical error in the internal structure of the file which is normally ignored by other playback software but causes the Classic to bail out.
    If you use Windows you may like to try scanning the files with MP3Validator which can find & fix some internal MP3 errors.
    Some users have also suggested that completely removing all id3 tags and then replacing the information can be a solution. This can be achieved in iTunes by selecting an affected track, right/control clicking and using the option Convert id3 tags> None. Since some files may mistakenly have more than one tag you may need to repeat this action. Once you have confirmed that no tag is present you can replace the tag information using Convert id3 tags > V2.3 (I believe it is recommended to avoid using V2.4).
    Personally I have found files for which these solutions don't work. In this case the workaround is either to re-rip the tracks or get iTunes to re-encode the file, e.g.convert AAC to MP3 or vice versa and sync the newly encoded file to the iPod instead. Because transcoding will cause a loss of fidelity you should keep your original file so that if a future iPod firmware resolves this issue you can put your original files back onto the iPod.

  • When saving my illustrator file to a pdf it doesnt show all the artwork ie boxes are hidden in the pdf or only showing part of them. How can I fix this?

    when saving my illustrator file to a pdf it doesnt show all the artwork ie boxes are hidden in the pdf or only showing part of them. Even some text is hidden. I have flattened the artwork so everything is in one layer. How can I fix this?

    Hi John
    I have indicated on the attached jpeg where the problem is, basically a line of text is missing at the top and part of the feeding diagram is missing. I created the artwork in different layer and then flattened. All text has been converted to outlines, however the areas being affected have no transparency, I have used solid fills or no fills. I get the same result when I export the file as a jpeg. Hope you can help.

    Create an action to do the crop and user the image processor to batch process your RAW files and have it use your cropping action in the process.

    Are you running the 9.0.1 Update of the program and on what computer operating system is it running?
    Is your video card/graphics card driver up to date according to the manufacturer of the card?
    Is your computer optimized, including maintenance of pile ups of preview files, conformed audio files, and conformed video files?
    Do you have the latest version of QuickTime installed on your computer with Premiere Elements 9.0/9.0.1?
    What are your project settings and what are the properties of your source media? When you say that "used to be able to export...." is that on the same computer, same brand/model/settings for the camera recording the video now in use, same Premiere Elements 9.0/9.0.1?
    Where player are you using for the playback of these exports?
    Please give us more details on the size of the projects (then and now) as well as details of the customized export settings in your Share/Computer/ route. Premiere Elements 9.0/9.0.1 is only a 32 bit application running in 32 bit or 64 bit system. Not sure if computer resources might be taxed more so now than before.
    More later.
