How to deal with the HDMI cable without sound? After the computer is connected to the TV, there is no sound on the TV, but the HDMI cable itself supports sound and audio transmission. Why is this? This phenomenon is mainly caused by several reasons.

What should I do if there is no sound when the HDMI cable is in use?

First, HDMI graphics card does not have a built-in sound card, this is more common in the NVIDIA chipset graphics card, with this graphics card, you need to connect the SPDIF output of the motherboard sound card and the SPDIF input of the graphics card (usually the graphics card will provide this wire, there will be Wiring diagram), otherwise, the HDMI graphics card has no audio input, and there is naturally no audio signal in the HDMI signal.

Second, for the use of HDMI graphics with built-in sound card (mostly ATI chipset graphics), this time there will be at least two sound cards (onboard sound card and graphics card built-in sound card), you need audio properties in the control panel In this HDMI graphics card built-in sound card as the "default sound card", you may also need to select the player's default sound card as the HDMI graphics card built-in sound card
