这是从 stackoverflow 交叉发布的，因为我在那里没有得到任何答案。
我正在尝试在 Ubuntu 20.04 上通过 Chrome 远程桌面使声音正常工作。我发现 ~/.config/chrome-remote-desktop/pulseaudio#ff31e90cfd 中有一个 default.pa 文件，其中包含：
load-module module-native-protocol-unix
load-module module-pipe-sink sink_name=chrome_remote_desktop_session file="~/.config/chrome-remote-desktop/pulseaudio#ff31e90cfd/fifo_output" rate=48000 channels=2 format=s16le
当我将此文件添加到 ~/.config/pulse 时，我有一个名为“~/.config/chrome-remote-desktop/pulseaudio#ff31e90cfd/fifo_output”的音频设备，它将通过 chrome-remote-desktop 发送声音。不幸的是，我不再有本地音频，并且我所有的常规音频设备都丢失了。因此，我尝试使用未修改的 default.pa 文件并将 chrome-remote-desktop 代码添加到其中：

我现在除了有一个名为“~/.config/chrome-remote-desktop/pulseaudio#ff31e90cfd/fifo_output”的音频设备外，还有常规音频设备，但不幸的是，这些设备都无法通过 chrome-remote-desktop 发送音频。它们都只能在本地播放。
有人能帮我设置一下，这样我就可以有本地和远程声音了吗？我觉得我已经很接近了，但我不知道下一步该怎么做。谢谢！

我创作了~/.chrome-remote-desktop-session如下的声音作品：
/usr/bin/pulseaudio --kill
/usr/bin/pulseaudio --start
/usr/bin/mate-session
我正在使用 Ubuntu MATE 22.04
