我想通过 HDMI 和 DP 输出声音。为了解决这个问题，我搜索了如何做到这一点并发现了这个：如何将独特的音频输出到 PulseAudio 卡的多个端口/配置文件？
我按照 @dirkt 的答案并在 中创建了一个新的配置文件/usr/share/pulseaudio/alsa-mixer/profile-sets/default.conf。
[Profile output:hdmi-stereo+output:hdmi-stereo-extra1]
description = Both
output-mappings = hdmi-stereo hdmi-stereo-extra1
input-mappings =
我验证了它可以与 gui 一起使用pavucontrol，并且它似乎可以工作。我在选项卡Both下有一个名为的新配置文件Configuration，在Output Devices我可以看到两者（HDMI 和 DP）。
但如果我播放音乐，声音将在通过 DP 连接的显示器上播放。通过 HDMI 的显示器没有声音。
附上一张图片pavucontrol（是的，我不知道屏幕截图，它是一个信息亭系统^^）。
我错过了什么吗？提前致谢！
