Solution to incomplete sound card driver in Win7 System

Solution to incomplete sound card driver in Win7 System

When installing Windows 7, many users may encounter problems where the system has no sound. The speaker icon in the lower-right corner of the taskbar is normal, and clicking and using it is normal, but there is no sound. How can this problem be solved? This may be caused by incomplete sound card drivers. The following describes how to solve these problems.

The procedure is as follows:

Step 1: You can perform a simple check. For example, whether the audio power supply and connection are normal, and whether the front or rear interfaces of the chassis are normal. If everything is normal, you can proceed to the next step.

Step 2: Open Device Manager to view the audio, video, and game controller directory. Generally, you will find that the device is abnormal. For example, Realtek High Definition Audio is normal, but the ati hdmi Audio column is marked with a yellow exclamation mark.

Step 3: Enable the driver genie. We recommend that you download the latest driver genie 2011 Beta 2. View the "multimedia devices" under "driver update". The interface provides a complete list of drivers that can be updated. For example, the Realtek Audio driver version 2.55 and the Realtek Audio driver version 2.57.

Step 4: download and install the new driver provided by the driver wizard. After the system is restarted, all problems will be solved.

The above problem occurs because the driver provided by default after the sound card is recognized by Windows 7 is incomplete and the HDMI part is missing. In this case, you only need to use the driver genie to detect and install the complete sound card driver!
