如何在 Ubuntu 16.04 上将 HDMI 声音输出设置为默认

我使用旧笔记本电脑作为 DVD 播放器，因此我希望声音始终通过 HDMI 播放，但每当我暂停声音时，就会切换回内部扬声器。我可以使用以下命令将声音更改回 HDMI：

pacmd set-card-profile 0 output:hdmi-stereo

我已编辑 /etc/pulse/default.pa 如下：

load-module module-stream-restore restore_device=false #added restore_device=false
...
#load-module module-switch-on-port-available #commented this out
...
set-card-profile 0 output:hdmi-stereo #added at end of file

这使得 HDMI 在计算机启动时成为默认设置，但在挂起时仍会切换回内部扬声器。如何永久将 HDMI 设置为默认设置？如果有帮助，则输出pacmd list-cards为：

更新：出于某种原因，将 /etc/pulse/ 复制到 ~/.config/pulse 使其工作。不知道为什么

答案1

我刚刚遇到这个问题。我按照@Nebuzaradan 在更新中所说的进行操作，结果成功了。我尝试了论坛上列出的许多其他方法，但没有一个有效，但出于某种原因，这个有效。

因此，重申一下，要解决此问题，请：

将 /etc/pulse/ 复制到 ~/.config/pulse
