HDMI realizes the connection between the TV and the computer, watching high-definition movies, or watching the screen of a large LCD TV. However, many users have a common problem when connecting TVs and computers with HDMI: There is no sound. At this time, how should we set it up?

4. In the Speech tab, click Test Hardware.
5, generally in the test process, the TV will appear sound.

Hardware failure If there is no problem with the settings and the graphics card driver is reinstalled completely or not, it is necessary to consider whether the interface is faulty or not, and whether there is a problem with the HDMI cable. It is best to replace the HDMI cable first and test it normally. Consider the hardware of the interface itself. According to experience, certain individual brands have requirements for the HDMI cable, and it is recommended to replace the HDMI cable. There is no sound but an HDMI cable.
The HDMI interface of flat-panel TVs has compatibility issues, and Japanese products of this type are more common. If you use the motherboard onboard sound card to connect the sound, you can try a HDMI cable, because some bad HDMI cable does not support audio output.
