Hearing music and sound
intensifies our enjoyment and excitement in using our computers, particularly
if the operating system installed is Windows 7, which is developed by software
development tycoon Microsoft Corporation. Although we can still use our Windows
7 computers even if we can’t hear sound, user interaction is highly diminished
most especially in events like movie watching and playing games.
Windows 7 No Sound – Reasons
System volume is muted.
Basically, if the system volume
is muted, you can never a sound whatever application you are using. To check if
the system volume of your Windows 7 computer is not muted, follow the steps
below:
1. Click the Start menu from the
task bar.
2. Head to the Control Panel.
3. Click Hardware and Sound and
then proceed to Sound.
4. Choose the Adjust System
Volume option of the Sound tab.
If you can see a red sign in the
volume slider then the volume system is muted. Otherwise, you need to move the
slider a little higher or to the level to which you can hear the sound. Make
sure you have not checked the MUTE option in the sound properties.
Software or multimedia player application is not properly installed.
There are instances that the
software we are using can be the reason why we can’t hear a sound. When dealing
with multimedia files like audio and movie files, there are the so-called
codecs that are important to play such object properly. If the multimedia
software used doesn’t support or doesn’t have that codec then the files will
not be played properly, thus you cannot hear a sound.
Corrupt files are played.
Corrupt files are other culprits
of the having no sound in your Windows 7 computer. Mostly, we can experience
corruption of multimedia or sound files when we have not downloaded or copied
it properly from the source. Moreover, there are also instances that those
files that underwent conversion from one format to another can contribute to
the sound problem of your Windows 7 computer.
Speakers are turned off.
When the speakers of your
computer are turned off, believe me you can never a sound. Speakers are used by
the sound card as a medium to which the sound is transported to the human ears.
Next time, make it sure that you turned on the power of the computer speakers
before blaming others.
Speaker cables are cut or are not connected properly to the right audio
jack.
To connect speakers to our
computers, we need cables. If you weren’t able to connect the speaker cable to
the right audio jack of the computer, you will surely experience the “Windows 7
no sound” dilemma. The appropriate audio jack for speaker cable is colored
green in most sound cards.
There are Windows 7 computers
that have three audio jacks; one for the output, the other is for input, and
the microphone jack. If you are going to connect the speaker cable to the input
jack then you will not hear a sound from the computer because it is not the
appropriate jack to use.
Sound card is not installed.
A sound card or audio card is a
hardware that is important so that sound and music can blast out from your
Windows 7 computers. It is the one responsible in handling the input and output
of audio signals from the computer to an external source like the speakers.
Obviously, if there is no sound
card installed on the computer, I am afraid you can never hear sound even a
beep from your device. You can follow the steps below in observing whether or
not your computer is installed with a sound card.
1. Click Start menu from the task
bar.
2. Go to the Control Panel and
then select System and Security.
3. Click the Device Manager
option from the System tab.
4. Expand the Sound, Video, and
Game Controllers category by double clicking it.
If you can see a sound card name
on the list, then you have an installed sound card, otherwise, you don’t have
any.
Note: You must an administrator privilege to view such advanced
computer management option. If you are prompted for a password, enter the
necessary identifications.
To fix your problem, you need to
install a sound card. You can either choose to install an internal or external
audio card. Internal sound card is needed to be integrated into the motherboard
of your Windows 7 computer. On the other hand, external sound card can be
attached externally to your Windows 7 computer, either through Peripheral
Component Interconnect (PCI) slot or Universal Serial Bus (USB) ports.
Incompatible or
defective sound card is installed.
Compatibility is an important
term to be considered when choosing sound cards or any other hardware that you
will connect into your computer. If you choose to install a sound card that is
only applicable for computers running the Windows XP operating system, you will
surely encounter sound problems if you install it into a Windows 7 computer.
So, before you are going to spend money in buying sound cards, make it sure
that it is compatible for computers having the Windows 7 operating system.
Meanwhile if the sound card
installed on your Windows 7 is defective, you cannot hear sound as well. You
will know if your sound card has malfunctioned if you have tried the best that
you can yet the solution is not fixed.
Corrupt or missing drivers
Aside from compatibility, drivers
are also important when it comes to sound card. Drivers are the ones
responsible in instructing the sound card during the manipulation of the input
and output of audio signals in and out of the computer. Sound cards are useless
without drivers. Likewise, corrupt drivers yield the same result as not having
a driver at all.
You will know if there is a
problem with your sound card driver if you can see a yellow exclamation point
in the name of your sound card in the Device Manager of the computer.
