  • My Pokerist app sound does not work, only with headphones....can anyone help me? Thank you

    My Pokerist app sound does not work.  It will only work if I have head phones on.  All other sound works, songs, video etc.  I deleted the app, then installed again still no sound.  It is not the app because I also have a IPhone and the sound works on Pokerist.  If anyone can help me I would appreciate it.
    Thank you

  • My iPhone's sound does not work except for the alarm and the volume bar is not there.

    Hi, thank you in advance if you can help.
    When my iphone 4 is not plugged in to headphones the sound does not work, and if I try to adjust the sound with the plus and minus buttons in the side it comes up like normal saying "Ringer" but then there is no bar underneath it. Sometimes the sound will work for a couple of minutes. However, there is definitely no problem with the speaker as the alarm always works perfectly fine.
    I have tried restoring it, this did not help.

    what you could even try is to write down a few contacts that you would need to get through a single day, restore it to factory, punch in those few odd contacts,
    No.  What he should be doing is syncing his contacts to an app on his computer or cloud service, then sync them back to the phone (without restoring the backup). 
    Never rely on the backup for contacts.  The contact info stored there may be incomplete and is only meant to maintain the recent calls and favorites lists.

  • After upgrading my Macbook to Yosemite, the volume icon at the top right is greyed out and sound does not work.

    After upgrading my Macbook to Yosemite, the volume icon at the top right is greyed out and sound does not work.

    Interesting bug. I'm cautiously optimistic this will get rid of the weekly annoyance. The difference is that I bought my laptop back in Feb 2015, so it came with Yosemite. I think the issue may have appeared soon after an OS update not long after I got the thing, though. I was using a sudo command in the Terminal, but that is obviously not a fix.
    I wonder if there is a broken .plist file that may be fixed ...?

  • HT201412 Sound works (songs) on Ipad 2 but sound on videos (example utube) sound does not work. Video plays with no issue.

    Sound works (songs) on Ipad 2 but sound on videos (example utube) sound does not work. Video plays with no issue.Mute us not checked in general settings. Reboot (off/on) has not helped. Deleted apps and reloaded them. Did not help. Any other suggestions thank you

    If you lose sound for games or other apps, email notifications and other notifications, system sounds may 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 control center. Swipe up from the bottom of the screen to get to control center . Tap on the bell icon and system sounds will return.
    If you have the side switch set to mute system sounds, then the screen lock can be accessed in the same manner as described above.
    This support article from Apple explains how the side switch works.

  • My sound does not work on my computer

    Hey
    I don't know if anyone can help me but my sound is not working on my computer. I went to my system preferences and when I click on output it says that the device has no output controls. I don't know why it is doing this. Can anyone help me to solve this problem?

    See:
    * https://support.mozilla.org/kb/No+sound+in+Firefox
    * https://support.mozilla.org/kb/Video+or+audio+does+not+play
    You can click the Volume icon on the Windows Taskbar near the clock and click the Mixer link at the bottom to open the mixer.<br />
    You can adjust the volume level for each application in that window, so make sure that Firefox is not muted or set at a low level.<br />
    Current Firefox versions use the plugin-container process to run plugins, so you need to check the volume setting for the plugin-container process.<br />
    You will only see the Firefox program or the Plugin Container in the Mixer if you are on a website that plays sound.

  • TS3274 sound does not work on my ipad, it worked early today, but now it does not, not sure what happen

    The sound on my ipad quit working, i was using it, and i went to do something, i come back to use it and now it does not work.  I have it on full volume.
    Can anyone help me please.
    Thanks Louise

    Try this  - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.)
    Check your settings. The iPads have a small switch on the right edge. It can be used as a rotation lock to keep the screen from automatically reorienting itself as you move around, but you need to have the tablet’s settings configured properly. That same switch, right above the volume buttons, can also be set to function instead as a mute button to silence certain types of audio.
    If the switch is set to work as a mute button, you can change its purpose to “screen-rotation lock” by tapping the Settings icon on the home screen. On the Settings screen, tap General on the left side, and on the right side of the screen flick down to “Use Side Switch to.” Tap to select Lock Rotation or Mute to set the button’s function. Even if you set the side switch for your preferred use, you can still mute the Mini or lock the screen. Just double-click the Home button, and when the panel of apps appears along the bottom edge of the screen, flick the row from left to right with your finger. Tap the icon on the far left side of the row to either lock the iPad’s screen or mute the iPad’s alerts, notifications and sound effects. Music, podcasts and video are not muted unless you turn the volume all the way down.

  • Apple USB keyboard does not work with one internal usb port

    Hi everyone,
    hope someone can help me to solve my problem. I have a MPB13 retina late 2013 since something like 3 months. I have additional screen (dell), usb wired keyboard (apple) and BT magic mouse.
    Since a few days, my usb keyboard does not work well. It only want to work properly when plugged to the rights side usb port internal port and not anymore on the left one. It also work on a usb external concentrator. Before, I had no problem, it worked perfectly. There was no problem such as cofee on it...
    After searching the web on such problem, I tries a few things such as:
    I tried the keyboard on another computer (windows): works fine
    I tried usb stick and external DVD reading on the left internal usb ports: works fine
    I switch the MPB off and turn it back on: the usb keyboard still does not work on the left usb port
    I tried the SMC and PRAM reset : nothing
    Any idea ??
    Thanks
    Guillaume

    I'm facing the same problem, found any solutions ?

    I have an iPhone App the was written for I think iOS 4.  Now under iOS 5 the sound does not seem to work.  I know this is very vauge but I have really no experance writting apps for the iOS.  I work mainly with Oracle Databases.  I had someone write this for me and now I can not reach them.  I am confedent with a little direction I can tackle this issue.

    I believe there are changes w/AVFoundation that need to be addressed in these cases.
    See the iOS 5 release notes in the Dev Center...

  • Sound does not work after sleep

    I'm really tired of this problem. Have a MBP Retina running the most current OS 10.8.4. Every few days or so when I wake the system (after having lid closed for a while, and Chrome browser running) sound does not come back on. So, if I am using youtube I can't hear anything. Only solution I've found is to restart the computer, which of course I don't want to do with browser tabs open, etc. etc.
    Isn't there a simple solution to this, before Apple finally figures out what causes this glitch?

    Finder
    Close all windows and quit all applications.
    Click "Go" menu in the Finder menubar.
    Select Computer, t hen Macintosh HD > Library > Preferences
    Open "Audio" folder.
    Right click these two files and select "Move to Trash".
    com.apple.audio.DevicesSettings.plist
    com.apple.audio.SystemSettings.plist
    Close the windows. Restart the computer.

  • My ipod say it has headphones in when it does not so the sound does not work. What do i do? I have already reset it a lot.

    My ipod sound is not working! I dropped it in water and it works fine but i can not hear anything. It say theat it has headphones in but there are no headphones in. What do i do? I have already reset it.

    Glad to have helped. One more thing to try, after drying your iPod. Try plugging and unplugging the headphone jack quickly about 12 times, it could be that the switch inside the port is stuck, many times this action will un-stick it. If the problem continues you may need to look into purchasing an out of warranty iPod, refurbished one are cheaper. Also, if you have not already done so, BACKUP ALL YOUR STUFF from this iPod to your computer, water damaged iPods have a habit of stop working without any notice. Hope this helps, Good luck.
