Headphones and speaker recognized as only one device.

That "no audio devices are installed" message does not refer to the headphones, but to the sound chip in the laptop. Your operating system is not seeing the laptop's audio chip, which is built into the laptop's motherboard. This could be due to a hardware failure, or a software problem (corruption of the audio chip's driver). To tell which of these is the problem, open "Device Manager" and look for any device that may be highlighted with an exclamation mark. If anything that resembles an audio device is so marked, it means the operating system is able to see the audio chip. and you problably don't have (total) audio hardware failure. You have to search, download and install the driver for this "problem" device. If no audio device is seen at all, then there is probably a hardware fault with the motherboard/audio chip. All is not lost. You can buy an inexpensive USB audio dongle that will allow you to route sound out from the laptop into external speakers or headphones. However, you'll lose the use of the internal laptop speakers that were dependent on the internal audio device (chip).

Most modern computers come with internal speakers already installed, especially laptop computers.
These speakers may be sufficient if you are performing typical computer tasks, but when you play computer games, listen to music or watch movies on your computer, you may want louder and more vibrant sound.
You can achieve this by installing external speakers or headphones. These can be connected to your computer through the speaker or USB ports included on your computer.

Plug in the speakers or headphones.
If the speakers or headphones use a stereo plug, insert the plug into the speaker/headphone port normally located on the side or front of your computer.
This port is often color-coded green. If the equipment is connected using USB, locate a free USB port.
Some external speakers will also need to be plugged into a power outlet in the wall or your surge protector.
This may be all you need to do to get the speakers or headphones to work. If they do not, continue to the next step.
Open the audio settings on your computer.
From the Windows Start menu, open the Control Panel. Here you will find audio and sound settings.
Click the heading to see your sound and audio options.
Choose "Manage audio devices" in Windows 7.


Find your Playback device.
In the Playback tab, you can select your speakers and set them as the default for your system.
If you do not see your speakers or headphones, they have not been installed properly. Disconnect and reconnect them to see if it corrects the problem.

Configure your settings.
Select your device from the list and click "Configure" to test your settings.
You can adjust the volume by using the volume slider on your computer's task bar or using external controls on the speakers or headphones.

Start button>settings>control panel>sounds and audio devices>

Middle tab [audio]
default device, hit the down arrow
and choose the other device


I keep a shortcut on quicklaunch because I switch them all the time.

possible causes:

1. volume was muted on PC
2. volume was too low
3. plug to wrong jack
   
4. faulty headphone
5. audio driver was not installed (check Device Manager)
6. faulty audio driver
   
7. use the wrong device for sound playback (Control Panell > Sound and Audio Devices > Audio tab)
   

From a distance, it sounds like you do not have the sound card drivers installed. Since it is a SoundBlaster card, go to creative.com and download a utility that finds, indentifies, and then installs the drivers for your sound card. That should fix the problem. If not, then you have other issues going on with motherboard drivers not being installed installed.
