When your sound card does not work, the first step is to check whether the sound card is physically installed correctly. If it is not, then you will need to carefully follow the instructions provided by the sound card manufacturer to make sure it is correctly installed.
Once the sound card is checked and installed properly, the next thing you should do is make sure that it is enabled and active in the device manager. To do this, press the Windows key + R to bring up the Run dialog box. Then, type “devmgmt.msc” and click OK. This will open the Device Manager window. Look for the entry for your sound card. If its status says “Not enabled” or “Disabled”, right-click on it and select “Enable”.
If the device is already enabled, then it is likely that the driver for the sound card is either out of date or corrupt. This can be fixed by downloading the latest driver from the manufacturer’s website and installing it. If this does not solve the issue, then you can try uninstalling and reinstalling the driver.
If these steps fail to solve the problem, then the next option is to check your system’s audio settings. To do this, open the Control Panel and select “Hardware and Sound”. Look for the “Sound” tab and click it. This will bring up the Playback and Recording tabs. Make sure the correct devices are selected as the default playback and recording devices.
If all else fails, then your sound card may be malfunctioning due to a hardware failure. In this case, you will need to replace the card with a new one.
In conclusion, the first step when dealing with a non-working sound card is to make sure it is correctly installed and enabled. After that, you should make sure the device driver is up-to-date. If that does not solve the problem, then you should check your system’s audio settings. Finally, if none of these steps work, then you will need to replace the sound card with a new one.
