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?

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.

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.

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

Check out this link - http://support.apple.com/kb/HT4085. There have been instances where settings have accidentally changed. Double click on the Home button, swipe all the way to the right to reveal the leftmost icon and alternate settings if necessary.

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 ...?

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.

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.

Microphone does not work after restarting computer

I just received the Creative Xmod soundcard yesterday after using an Icemat siberia usb headset sound card for a couple months. The sound is a lot better with the creative soundcard however, if I restart my computer and go back into ventrilo, my microphone does not work. It doesnt make any sound when I talk into it (almost as if it muted itself) but it hasnt. I check my sound settings and everything is the way it should be.....but the mic isnt producing any sound. It is not my headphones that is causing the problem because I have never had this problem with my old icemat soundcard. I am currently using :
Sennheiser PC350 headset
Windows XP Home Edition
The newest version of Ventrilo

That is how I have ventrilo setup. A friend of mine said I should Mux set to Record Control, but it only gives me the option for Wave In =/

Itunes 8.02.2 does not work on my computer

Hi,
*I have a dell computer runing xp sp3 pro verison. I installed Itunes 8.02.2 then I restart my computer Itunes does not work for me at all. I have no malware or spyware on my computer. I have tried the tips on apple web site to make itunes start up and work. So I remove 8.02.2 itunes from my computer. Then I installed 8.01.11 the old version of Itunes and it works just fine on my computer. I think that 8.02.2 has a lot of bugs in it. Also, I have a dell notebook with xp sp3 home and the same problem happends to my with version 8.02.2. I got itunes to work on my notebook buy installing 8.01.11. I hope people tell apple that there are some problems with 8.02.2.*
I hope apple comes out with a new version of itunes that don't have problems like 8.02.2
*Thanks alot*

I followed the instructions posted in http://support.apple.com/kb/HT1737 and dont work.
1) My iPhone battery is 100%.
2) My PC is a notebook, and only have USB ports at the keyboard.
3) & 4) I turned off/on several times the PC and the iPhone.
5) Uninstall (reboot pc) and reinstall iTunes.
Where can I download a previous version of iTunes?
Thanks in advance.

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.

My sound is not working with the computer speakers and with headphones, help?!

my sound is not working with my headphones or the the computer speakers

You indicate you have a "brand new Air", you have a 14 day exchange, and the warranty of which you paid for regarding genius bar in-shop diagnostics (and repair if necessary)
What year model Air do you have?
On the first question,....are the headphones attached when you have your Air in sleep?
If yes, then refrain from having phones attached when you close the monitor to prevent this until it is resolved
resolution as to same yet, no.

I have an iPhone App and now he Sound Does not work

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...
