我正在尝试将“内置音频模拟立体声”分离为两个独立的设备（前面板音频和后面板音频，它们目前是合二为一的）。在 Kubuntu 14.04 上使用 Realtek ALC887。我以前在 Windows 中单独使用过前面板和后面板，效果很好，所以我知道声卡可以做到这一点。
我跟着这并将以下几行添加到我的 /etc/pulse/default.pa 的底部
load-module module-remap-sink sink_name=speakers remix=no master=alsa_output.pci-0000_00_14.2.analog-stereo channels=2 master_channel_map=front-left,front-right channel_map=front-left,front-right
load-module module-remap-sink sink_name=headphones remix=no master=alsa_output.pci-0000_00_14.2.analog-stereo channels=2 master_channel_map=rear-left,rear-right channel_map=rear-left,rear-right
我还尝试使用“channel_map=front-left,front-right”，如链接所示
它让我成功了一半，它在我的播放设备下给了我两个“重新映射的内置音频模拟立体声”设备，但第一个仍然只是结合了我的扬声器（后面板）和我的耳机（前面板），而第二个没有效果。
在此之前，我只能通过耳机获取音频，但一旦我使用 hdajackretask 并设置我的端口，我就能让音频通过它们两个。
“pacmd list-sinks”输出（不包括我的 HDMI 音频和键盘的音频插孔）：
最后两行显然是上面两行相加的结果

有什么方法可以解决我遇到的问题（上面加粗的部分）？或者是否有其他方法可以实现我的目标？
抱歉，如果我的措辞让人困惑，这对我来说是一个全新的领域。任何帮助我都非常感谢！
答案1
好的，我已成功设置了不同的设置。希望这对您有所帮助
首先，我的立体声音响插入绿色端口，耳机插入主板上的黑色端口（红色为麦克风）
在 pavucontrol 配置菜单中，我设置 模拟环绕 5.1 输出 + 模拟立体声输入查看我的内置音频配置文件
名称取自pacmd list-sinks：alsa_output.pci-0000_00_1b.0.analog-surround-51
/etc/pulse/default.pa：
load-module module-remap-sink sink_name=speakers remix=no master=alsa_output.pci-0000_00_1b.0.analog-surround-51 channels=2 master_channel_map=front-left,front-right channel_map=front-left,front-right
load-module module-remap-sink sink_name=headphones remix=no master=alsa_output.pci-0000_00_1b.0.analog-surround-51 channels=2 master_channel_map=rear-left,rear-right channel_map=front-left,front-right
重新启动 pulseaudio：
pulseaudio --kill
pulseaudio --start
现在，我可以从 pavucontrol 设置重新映射内置音频模拟环绕 5.1（遗憾的是，名称没有显示。。）每个应用程序都可以在耳机和立体声之间切换
编辑：当我第一次尝试像您一样在前面板上实现此效果时，我注意到当我插入和拔出耳机插孔时，pavucontrol 中的配置文件会发生变化。如果您在尝试这些重新映射之前为两个端口设置相同的配置文件，可能会有所帮助。
答案2
您使用了master_channel_map=rear-left,rear-right channel_map=rear-left,rear-right第二个，但实际上应该是master_channel_map=rear-left,rear-right channel_map=front-left,front-right。
