电脑使用HDMI线连接电视后没有声 win7/win10解决方法

更新时间：2026-08-22 11:51:27 | 编辑：冰魄 | 信息来源：互联网
电脑使用HDMI线连接电视后没有声怎么办？HDMI是电脑连接数字电视时常用的高清数据线,这条线不仅能传输视频信号,还能传输音频信号,但有用户却发现使用HDMI线连接电视后没有声音,这是怎么回事呢?下面就随小编一起来学习一下电脑使用HDMI线连接电视后没有声的解决方法吧。 　　使用HDMI线连接电视后没有声音的解决方法： 一、使用HDMI连接电视后电脑上的视频信号和音频信号都传到了电视上，如果没有对音频进行正确设置就可能会出现没有声音的情况。 　　1、右键桌面右下角的音量图标，点击“播放设备”，如图所示：
  　　2、在播放设备中右键每一个设备，点击测试，哪个设备是有声音的就将哪个设置为默认设备，如图所示：
 

二、因为HDMI信号传输是通过显卡来完成的，所以显卡声卡驱动不正确也会导致这种情况。

安装打开360驱动大师，然后检升级显卡音频驱动



  　　以上便是使用HDMI线连接电视后没有声音的解决方法了,希望该方法对大家有所帮助
