我有一个通过hdmi连接到投影仪的ubuntu 16.04,我已经配置了选择HDMI输出的声音,
如本网站https://itsfoss.com/how-to-fix-no-sound-through-hdmi-in-external-monitor-in-ubuntu/
事实是,如果我播放YouTube视频或其他应用程序,则音频是由投影机播放的,但我想要的是
将通过声卡线路输入的音频发送到投影机,而我不能。如果我选择扬声器,则进入该行的音频
如果播放正确。这种情况是输入的配置表如果移动,那么如果音频进入,问题是它不会出现在hdmi上。
我看了看alsamixer,看来还可以,具有hdmi输出的图形卡驱动程序可能有问题吗?安装的驱动程序是默认的。系统是新安装的。

声卡已集成到主板中。我已经用一个简单的USB卡进行了测试。
有什么想法吗? (Windows上的相同情况也很好。我已经在另一台装有Ubuntu 16.04的计算机上安装了不同的硬件,并且得到了同样糟糕的结果)
