在 pulseaudio 中禁用端口

当我运行 Steam 流媒体会话时，主声卡上选择的端口不断切换回扬声器。

我可以在哪里配置 pulseaudio 以完全禁用其中一个输出端口？

答案1

笔记：如果您希望长期禁用某个端口，我建议您使用此方法。如果您想要修复不需要的自动端口切换，并且仍然能够使用所有端口，我建议您使用其他解决方案。

要完全禁用端口：

导航/usr/share/pulseaudio/alsa-mixer/paths

找到.conf您想要禁用的端口的文件并添加.backup其名称。

对于你的情况，你可能需要analog-output-speaker.conf改为analog-output-speaker.conf.backup

这使得该文件对 pulseaudio 不可见，但将其保留为备份。

为了使更改生效，请注销并重新登录。

答案2

要长期禁用端口：

  • 通过 识别要禁用的端口pacmd list-cards。
  • 编辑/usr/share/pulseaudio/alsa-mixer/profiles/defaultconf。
  • 注释掉每一个包含您的端口的块（例如hdmi-output-2）。
  • 注销并登录。

在 Ubuntu 18.04 上，禁用 alsa-mixer 的解决方案paths不起作用，您必须编辑profiles。

答案3

记录一下：我遇到了插入耳机线的问题，导致顽固地切换到耳机的麦克风（虽然没有麦克风）。我是这样解决的：

sudo vim /usr/share/pulseaudio/alsa-mixer/profile-sets/default.conf

;paths-input = analog-input-front-mic analog-input-rear-mic analog-input-internal-mic analog-input-dock-mic analog-input analog-input-mic analog-input-linein analog-input-aux analog-input-video analog-input-tvtuner analog-input-fm analog-input-mic-line analog-input-headphone-mic analog-input-headset-mic
paths-input = analog-input-front-mic analog-input-rear-mic analog-input-internal-mic analog-input-dock-mic analog-input analog-input-mic analog-input-linein analog-input-aux analog-input-video analog-input-tvtuner analog-input-fm analog-input-mic-line

基本上我消除了*head{set,phone}-mic周围的任何“

然后pulseaudio -k && pulseaudio --start重新启动它，现在它总是强制使用内置麦克风，一切正常
