Its the driver

1. Look for your laptop model (typically on a label under the battery (if you can't find it, go to step 1.5)
1.5. Open up "computer" in the start menu, right click an empty space, select properties from the menu, look for "model"
2. Go to your laptop manufacturers website (eg asus.com lenovo.com etc)
3. Look for a support link, this is typically in the upper right of the page
4. Look for drivers and downloads
5. Some websites have auto-detect, but if not, look up your laptop model number
6. Find "audio drivers" and download the latest one
7. After its downloaded, install it
8. After install, reboot

Go to control panel and then sound and check is something disabled if is enable. Or you can also check device manager is there any sound drivers disabled. To get acces to device manager or control panel just write it to click windows logo (start)
