从 22.04 升级到 24.04 后，切换到 USB 耳机效果不佳

  • 772

我使用 NVIDIA GPU 的声音输出作为主声音接收器。不过，我时不时会插入 EPOS 耳机（一种与实际耳机进行无线通信的 USB 适配器）。

在 KUbuntu 22.04 下，pulseaudio 会自动切换到 EPOS 进行声音输入和输出。

自升级到 KUbuntu 24.04.1 以来，此功能一直无法正常工作，而且我无法调试它，因为我不熟悉 pipewire 也不熟悉 pipewire-pulse“桥”。

插入 EPOS 加密狗后，切换无法正常进行：在 pavucontrol 中，EPOS 显示为默认源和接收器，但没有实际声音。我可以通过使用 pavucontrol 选择 NVIDIA GPU 作为默认设置，然后再选择 EPOS，使其正常工作。

有一次（在网络会议期间），我突然没有声音了。我通过在 pavucontrol 中执行相同的操作恢复了声音。但当我关闭 pavucontrol 时，它又出错了。然而，这并不是系统性发生的，而是随机发生的。

我认为我的配置对于从 22.04 升级到 24.04 来说非常标准。我所做的唯一更改是在/bin/true下创建了一个符号链接$HOME/bin/pulseaudio：这使游戏 (Victoria 3) 能够正确检测 NVIDIA GPU 声音接收器（否则它将输出到计算机机箱的内置扬声器）。

仅供参考，网络会议是在 Firefox 下使用 Big Blue Button 进行的（直接从 Mozilla 获得，而不是 snap distrib）。

pactl list这是EPOS 加密狗工作时输出的开始部分（是否有 pipewire 的等效项？）：

    在调查为何pipewire-session-manager.service被报告为时Loaded: error (Reason: Unit pipewire-session-manager.service failed to load properly, please adjust/correct and reload service manager: File exists)，我偶然发现了一个可能相关的早期问题。

    尽管从那时起事情（特别是包裹名称）似乎发生了变化，但我尝试了接受的答案：

    sudo mkdir -p /usr/share/pipewire/media-session.d
sudo touch /usr/share/pipewire/media-session.d/with-pulseaudio

    我完全不知道这实际上是做什么的，但今天插入我的 EPOS 耳机的 USB 加密狗会导致系统自动切换到它，而拔出则会导致它切换回 GPU 输出。
