我已经为此苦苦思索了近 6 个小时，但我完全被难住了。

我有一副 Logitech Pro X 耳机，刚刚从 Windows 切换回 Mint（您没有将 AI 塞进我的操作系统！），我正尝试让环绕声在其上运行。

我的规格（供快速参考）：

  • Linux Mint 21.3
  • 内核版本 5.15.0-116-generic
  • PulseAudio 版本 15.99
  • alsa-base 版本 1.0.25

aplay -lL列出耳机具有高达 7.1 的环绕声：

同样地，alsamixer：

alsamixer 显示 PCM 和自动增益控制，但没有其他内容

最后，确实speaker-test -D default -c 8运行了，但仍然只在立体声模式下运行 - 也就是说，所有的通道都被挤压到左边、右边或两者。speaker-test -D surround71:CARD=X,DEV=0 -c 8返回Broken configuration for playback: no configurations available: Invalid argument。

我已经创建并daemon.conf修改了、和 LFE 设置，以及添加 （我相信我已经按正确的顺序进行了映射，但我尝试了几个 - 包括 5.1 环绕声 - 但都没有起作用。）default.pa~/.config/pulsedefault-sample-channelsdefault-channel-mapload-module module-combine channels=8 channel_map=front-left,front-right,rear-left,rear-right,front-center,lfe,side-left,side-right

到目前为止，我读到的所有内容都表明它应该开箱即用，否则上述更改将使其正常工作。我甚至安装了 pipewire，但遇到了其他我无法理解的问题。我也研究过 dcaenc，但我的理解是它需要使用正确的音频编解码器格式化传入的音频，这显然不适用于游戏耳机。

任何帮助都将不胜感激 - 特别是如果他们可以解释一下幕后发生的事情。

后期补充：似乎aplay还列出了我的 Vive 具有 7.1 环绕声，但 PA 也拒绝识别它。很奇怪。
