There can be a number of reasons if your computer doesn’t play any sound at all. Sounds include Windows basic sounds, music etc.
What to Check:
- Sound Hardware is present or not
- Device Drivers are installed or not
- Speakers/Headphones wires are connected properly
- Check if mute button is pressed
- Sound/Audio Hardware is Enabled from BIOS
Sound Hardware/ Sound Card:
Sound Hardware is commonly known as sound card. If you have a desktop system & have installed a add-on sound card for high performing sound, the first step would be to open the cabinet and check if the sound card is installed into the slot properly.
If you have a laptop ( notebook/netbook/ultra book), there are very slight chances that you have a Add-on Sound card installed.
To Check the sound card from within windows:
Go to Device Manager,
To open Device Manager:
Control panel –> small icons –> Device Manager,
type device manager directly into the start menu search box ( Windows 7 only )
See the below screenshot and check if the sound, video & game controllers shows your Audio hardware installed.
To Check if Device Drivers are Installed or not
If you see a Exclamation mark on any listed hardware or see a yellow question mark saying other devices, it is quite possible that either the device drivers that are installed for your device are faulty or there are no drivers installed.
To resolve, right click the hardware listed either in other devices or with an exclamation mark & click on update drivers & let Windows search the Windows Update service for any new drivers that might be available for your device type.
You can also visit your computer manufacturers support website & try downloading the drivers from there. * refer your computer documentation.
If you see no hardware present within the sound, video & game controllers, you should try pressing the Scan for hardware changes button just below help ( refer screenshot above). If there is no response from the device manager after refreshing you might be facing a hardware issue or Your Audio Hardware might be disabled from your BIOS options. ( To enable/ check BIOS settings go to the end of this page).
To Check if Speakers/Headphone wires are connected properly
There is no special guide relevant for this, but if you really don’t know how to check a loose connection, follow the wires connecting your computer to your speakers/headphones and vice-versa. Tighten if loose.
Check if the wires are plugged into correct slot
if you are using a desktop PC, see the image below and confirm all the wires are plugged into the right slot.
Also, check for faulty speakers/Headphones.
Check if the mute button is pressed
Sometimes a hotkey or otherwise the mute key gets activated and we just don’t pay attention to the muted volume button in the taskbar. refer images below
If you see the muted icon in your taskbar click on it to unmute. Also check the volume level and increase if necessary.
Check if Sound/Audio Hardware is Enabled from BIOS
To do this, refer your motherboard/system maintenance manual & looks for things given below:
- Press Del or F2 or F10 or any other key depending on your system type & make
- Advanced Options/ Integrated Peripherals
- Enable Onboard Audio/ AC’97/HD Audio
- Enable it
- F10 ( Save & Exit )
