Low speaker volume

The final volume depends on de Hardare and on the application you are running (audio/video(phone).
First of all, try to find in your keyboard colored sound symbols, usually red small for lower and big for raising volum in some standard (F11-F12 ??) function keys which works when activated simultaneous with "windows" key between left ctrl and alt keys. Your screen must show then volum control while in use. If it is at maximun you have to check it down in the individual volume control of your application.

Dell latitude D610 will not unmute

    • 1 Click on the speaker icon in the system tray of your windows 7 screen, located in the task tray by the system clock. This will cause a volume adjustment screen to pop up. Drag the volume slider to adjust the volume higher or lower.

      Right-click on the speaker icon and select "Open Volume Mixer" to manually adjust the volume of each device separately, using the same method as in step 1.

    • 3

      Right-click the speaker icon and select "Sounds" to change which sounds play for specific events, such as Windows Startup, Windows Logon and System Notification. This should bring you directly to the "Sounds" tab of the sound menu, where you can click the program event from the list and change the sound using the drop-down menu at the bottom. You can choose "(None)" to disable the sound.

I am trying to find out what the blue symbols on the function keys of my sk 9020 keyboard stand for

The blue keys serve as a secondary function for your volume control, monitor controls and pause play fast forward rewind (in media mode). In order to use the blue keys that are numbered from F1 to F12, you must depress and hold the Fn key that is located at the bottom left side of the keyboard. Here is a way to test it: Open up any file that plays sound for longer than 1 minute (60 seconds). While this file is playing, hold down the Fn key and simultaneously press F8 and listen to the volume get louder or Fn and F7 together and listen to the sound get lower. The picture of the crescent moon F1 will adjust the brightness of your screen. F2 will magnify your screen. F3 will take you to your email. F4 will take you to your internet home page. F6 will mute the volume. F7 will lower the volume. F8 will raise the volume. F9 will rewind your video playing. F10 will stop the video. F11 will pause or play the video. F12 will fast forward the video.

No sound from the computer, i need the audio controller driver

I will gve you a couple of things to try first;
1 Find your speaker icon in your taskbar, lower right of screen. Is there a red x on it? Right click on it and a window should come up with your device. It should show a green check on left and power bars on right> right click on the device. A window will pop up and you should see "disable". If you see "enable" click on that and exit. Right click on speaker again and click on "open sound mixer" and adjust your volume.
2 Clcikon "start" find "control panel" and click on to open. In your list(icons), find "device manager". Right click on that, open and click on continue. Click on the box with + next to "sound audio and video controllers". You should see a drop down with your device. right click on it and you should see "disable". If you see "enable" click on that and exit. Right click on it again and click on the "properties" tab You should see "this device is working correctly". Exit that and click on your speaker icon and open your sound mixer to adjust volume.
If this doesn't work please provide me with your computer make and model, Your current Windows version and, a complete manufacturer and model number for *********** board( AMD's board was used by alot of different manufacturers, ie, Pc Chips. Let m know at "add a comment"

I dont have no sound device?

I will give you two ways to check your sound.
1 If you have a speaker symbol in your taskbar at lower right of your screen, right click on it. Click on "playback devices" A window should pop up with your devices. If it's on board sound would probably be Realtek and show up as HD device, Anyway, right click on it and you should see "disable". If you see "enable", click on that and exit. If you don't see anything in window, click on empty window then click on "show disabled devices" If anything pops up right click on that and click "enable". If you have enabled your device, right click on speaker again and click on "open sound mixer" and adjust your volume. By the way, did your speaker have a red x on it before? Does it now?
2 Click "start" in lower left of your screen. find "control panel", click on and open. In your list(icons) find "device manager". Right click on that, open and click continue. Click on the box with + next to "sound audio and game controllers". You will see a drop down with your device(s). Right click on your device and you should see "disable". If you see "enable" click on that and exit. Right click on your device again and click on the "properties tab. You should see "this device is working properly" Now go back to speaker symbol and adjust your volume.
Does SP1A refer to a service pack you just installed? Taht may be what knocked out your sound. If this did not help you or if you have any questions let me know at "add a comment"

No sound on Powerbook G4

so not to be obvious but you have one of two problems either hardware or software. there is a way to check but you need to do a few things. first you should try creating a new user account and see if the volume problem still exists. you create a new user through system prefs/accounts. if that doesn’t work you should try a pram reset by holding down the cmd, option, r, p, key at boot. IF you have never done this before you want to hear the startup chimes at least 3 times then let the computer restart. if that still doesn’t work you should try an archive and install of the os from the discs if you still have them, and if none of that work you most likely have a hardware issue and either the logic board needs to be replaced or the speakers are bad. but either way its going to cost money if there is a hardware issue and you might consider a new computer, im just being honest.

Volume problems on my Apple MacBook

Hi, Sorry you are having problems,
If I understand you correctly, you have your headphones plugged into the MacBook and are expecting sound to come out of your speekers ?
Well, if that is the case, you must know that the mac will automatically cut the signal to the speekers as soon as headphones are connected.
Now if you are saying that you connected the headphones to test it and found that whe you changed the volume, you could hear the change on the headphones, but when you unplug your head phones, you do not notice any sound difference on the speakers.
SO let's say that is the problem. First thing to always do, of course, is a full shut down and a clean start up with no headphones installed. Once you have booted up, try it again....
If it still does not work, go into your sound preferece pane in the system preferences and change some of the settings, like muting the sound and clicking the button that allows for showing volume in menu bar, unclick options go into the tabs go clicking and unclicking things... then quit and then go back into the sound preferences and set it the way you want, sometimes shaking it up a bit gets it back on track...
Good luck.

Speakers are disabled and can only listen through headphones

My daughter had the same problem. What has probably happened is that the chip that is inside the headphone outlet has become stuck and your macbook thinks the headphones are always plugged-in. There are several suggestions that we tried but decided to send her macbook back to Apple for a new chip. This is a KNOWN problem. For more detailed info and suggestions try Good luck!
