This check is especially important for laptops and tablets because their speakers are small and it is difficult to hear sound if the volume is too low.

Step 3: Update the Driver To let Windows recognize your sound card or sound processor, you need to install a compatible and working driver. Expired, incompatible, or corrupted drivers may disrupt communication between the computer and the sound card.
If you recently upgraded from one version of Windows to another, the current sound card driver may only work with previous versions of Windows. If you have recently experienced a power outage, ** or other computer problem, the driver may be corrupted. In rare cases, when Windows cannot automatically update the sound card driver, you may need to download and install the latest drivers for your sound card to help resolve such issues.
There are three ways to find and install drivers:
1. Use Windows Update. Windows Update automatically downloads and installs recommended updates. Install all important, recommended, and optional updates to update system features and other software, which may help resolve your sound issues.
2. Install software from the device manufacturer. If the device comes with a CD, the CD may contain software for installing device drivers.
3. Download and install the driver yourself. You can search for drivers on the manufacturer's website. If Windows Update does not find a driver for your device and the device does not come with the software to install the driver, try this method.
