我有一个 Arozzi Sfera 桌面麦克风。它的背面有一个耳机插孔，我猜是用来接显示器的。
连接麦克风后，我可以在设置视图的“声音”选项卡中看到各种音频输出设备，包括我的蓝牙耳机、显示器的 HDMI 连接和麦克风。当我选择任何输出设备并使用“测试”功能时，音频会直接发送到麦克风的耳机插孔。
我尝试运行pulseaudio -k，但当systemctl --user restart pulseaudio.service问题出现时，却无济于事。

通过数字卸载 alsa-card 模块（pactl unload-module 8在这种情况下）也会禁用麦克风作为输入。
pactl info告诉我默认接收器是bluez_sink.2C_4D_79_40_C5_3B.a2dp_sink。当我从设置中更改音频输出时，这会发生变化。
一个可能相关的问题是，当我断开并重新连接麦克风时，我可以在音频设置中看到麦克风作为“默认”输出。
另一个观察结果是，当我在应用程序设置中明确设置音频接收器时（例如在 Discord 桌面应用程序中），它可以正常工作。似乎只有默认接收器和/或 gnome 才会表现出这种行为。
今年 3 月底左右，这种现象似乎变得很常见。我知道它在 30 日运行正常。我唯一的解决办法是拔掉麦克风。
我想知道如何修复这个问题。如果修复不了，我想知道如何诊断这个问题，以便我可以向正确的一方提交错误报告。
答案1
我相信我已经找到了解决方案。使用pavucontrol，我找到了麦克风的音频配置文件，为其配置的配置文件是“数字立体声输出+单声道输入”，这让 pulseaudio 感到困惑。我相信这是iec958-stereo+input输出配置文件。
将其更改为“单声道输入”（我相信是这样mono-fallback）可以解决问题。
