耳机声音输出与 Line-Out 输出混合（ALSA 驱动程序问题？）

  • 772

我遇到了与此问题中描述的完全相同的问题：耳机声音输出与线路输出混合。不幸的是，这个问题没有发布答案。我不确定以这种方式发布问题是否合适（我是这些论坛的新手），但我已经尝试了几个星期来解决这个问题，但没有成功。

我遇到此问题的系统使用带有三个模拟输出的 CS4207。三个输出中只有两个连接：耳机和线路输出。我在 Windows 上测试了音频硬件，并验证所有硬件均按预期运行（这和我进行的其他一些测试使我相信这是 Alsa 或 pulseaudio 的驱动程序问题）。

我看到的问题如下：当选择 Line Out 作为声音输出时，声音按预期工作（即，声音仅来自连接到 Line Out 端口的扬声器），但是当选择 Headphones 作为声音输出时，声音来自连接到 Headphones 端口的扬声器和连接到 Line Out 端口的扬声器。

通过 Alsamixer 查看声音设置同时更改所选的输出设备有助于说明问题。

当选择 Line Out 为输出时：

LineOut_selected_output

当选择耳机作为输出时：

耳机_选定_输出

正如您在此处看到的，当选择 Line Out 为输出时，耳机会自动静音并将音量设置为零，但是当选择 Headphones 为输出时，Line Out 音量和静音设置不会受到影响。

为了解决这个问题，我一直在进行修改/usr/share/pulseaudio/alsa-mixer/paths/analog-output-headphones.conf，虽然我可以看到更改正在应用（声音设置更改和 alsamixer 更改），但我还没有找到具有预期效果的修改。

我不确定下面的任何内容是否有用，但我将重现原始帖子中生成的输出，这些输出指出了这个问题（以下输出来自我的系统，我只是运行与原始帖子相同的命令）。请注意，在运行这些命令之前，我已将所有修改恢复到 analog-output-headphones.conf。

    我终于搞明白了。非常感谢：

    解决方案如下...

    添加底部的/usr/share/pulseaudio/alsa-mixer/paths/analog-output-lineout.confadd：

    [Element Line Out]
switch = mute
volume = merge

    添加底部的/usr/share/pulseaudio/alsa-mixer/paths/analog-output-headphones.confadd：

    [Element Line Out]
switch = off
volume = off

    注意：这些文件中声明出现的顺序.conf很重要。我曾将这些[Element <name>]声明添加到这些文件的中间，但这导致了问题。我建议先将它们放在底部，如果不行的话，将它们稍微移动一下（我还没有彻底测试过移动它们，所以这个建议可能是个幌子，如果你发现是这种情况，我很抱歉）。
