如何创建同时使用 HDMI 和音频立体声输出的配置文件？通常，当我想使用 HDMI 时，必须打开 pavucontrol 并在配置选项卡中选择 HDMI。当我想返回线路输出时，我必须再次选择音频立体声输出。我如何才能同时使用这两个输出源？由于它们位于不同的配置文件中，我无法同步它们。

此外，使用 xrandr 我可以看到我正在使用 HDMI-2，而使用 HDMI 配置文件运行的 pacmd list-cards 显示我正在使用 hdmi-output-0
答案1
运行paprefs，如果没有，可以用apt安装。
最后一个选项卡是Simultaneous Output，那里有一个选项，可以添加一个新的虚拟设备来同时播放音频全部设备。
然后pavucontrol您应该能够选择同步虚拟设备。
