如何将 pacmd 接收器列入黑名单？

我不希望我的计算机的输出更改为特定接收器（有时接收器会在重新启动时切换）。
我无法将接收器固定为恒定，因为我希望在连接蓝牙耳机时更改默认接收器。

这是我不想连接的水槽 -

答案1

如果您在插入设备的情况下启动，@Arthur 的答案就有效。但是，如果它是热插拔设备，则无法正常工作。 PulseAudio 14 似乎通过为 HDMI 输出添加默认黑名单选项来解决您的问题（特别是切换到 HDMI）。就我而言，我想将我的 CalDigit 坞站列入黑名单，因此我进行了/etc/pulse/default.pa以下修改：

.ifexists module-switch-on-connect.so
load-module module-switch-on-connect blacklist="CalDigit|hdmi"
.endif

文档在这里：https://www.freedesktop.org/wiki/Software/PulseAudio/Documentation/User/Modules/#module-switch-on-connect

答案2

您可以将默认配置文件设置为关闭，/etc/pulse/default.pa例如

set-card-profile alsa_card.pci-0000_0a_00.1 off
