HT-RT5音响连接海信的电视是用HDMIARC接口也没有声音这个怎么弄
推荐回答（5个）
第一：厂家在设计电视机的时候，是有电视机本身解码发声音，默认是电视机本身发身，电视机内置扬声器发声音。第二：如果你需要接同轴到功放上，那你就需要把电视机的声音设置成同轴输出（或打开同轴输出），还需要把声音设置成外置扬声器，那样声音才是从同轴输出。第三，这样设置后，如果电视机本身没有声音了，那说明声音设置成了同轴输出，然后只需要把你功放设置成同轴输入模式，那样功放才会对数字同轴输出的信号进行处理发声。、
常见问题：
（1）海信液晶电视后面的vga音频接口接音箱为什么没有声音？
VGA音频接口是作为输入音频信号用的不是用来输出音频的，如果你要把电视机的音频信号输出到你的音响可以接电视机的耳机接口（输出线跟电脑音响线一样的），如果你的电视机没有耳机接口功能的话可以接电视机后面的AV音频信号输出，找一跟两头AV线就可以了，就是放碟机那种线！ 你是想把电脑音频信号输入到电视机里面还是输入到你家音响啊？如果是到电视机里面就必须找一条VGA音频信号线接VGA音频输入端子，如果是想把电脑音频信号输入到你家音响直接将电脑音频线接到你家音响就OK啦！
（2）海信电视外置音箱之间是怎么连接的？
智能电视外接音响直接用音频线将电视机和音响连接起来即可；
方法为：1）准备一条双声道的音频连接线，一头插入电视机的音频输出接口，另一头插入音响的音频输入接口，注意插头和接口的颜色要一一对应的。2）接好以后，开启电视机和音响；电视机就会将音频信号传输给音响，把声音播放出来。
如果你的音响带有高清接口的话，可以用高清线从电视机的高清输出接口连接到功放上的高清输入接口上。连接好后应该还要调节功放上的音频输入选择按键或者调节旋钮，使功放上的音频通道将高清信号导通才行。
另外，如果电视机和功放都带有数字同轴接口的话，最好用同轴线对应连接使用，这样效果会更好。
第一刚开始我以为高清线是插在功放输入，看了下功放说明书才知道是插输出，你看下线别插错，第二在电视设置里声音设置下回传项
如果你是想用HT-RT5播放电视的音源，按以下步骤操作，我家海信电视，索尼HT-NT5音响，亲测有效：
1.用HDMI线连接电视和音响两端的HDMI ARC接口
2.进入电视机的设置，声音，声音输出选择HDMI ARC
3.进入索尼音响主界面，选择TV（左上角第一项）
4.用电视内置应用比如爱奇艺视频等，声音就从索尼音响出来了
