我有一台华硕 ROG G752VY，双启动，安装了 win 10 和 Ubuntu 15.10
在 Windows 上一切都运行良好。切换到 Ubuntu 后，扬声器工作正常，但只要我插入耳机，就什么也不工作了。
我补充道
options snd-hda-intel model=asus-mode5（我也尝试了 asus-mode1 到 8）
到/etc/modprobe.d/alsa-base.conf
耳机现在运行良好，但声音仍然通过扬声器播放。
跑步cat /proc/asound/card0/codec* | grep Codec我得到Codec: Realtek ALC668
另外，内置麦克风无法工作，尽管它在 Windows 下可以正常工作。
有任何想法吗？
编辑：自动静音已启用alsamixer
编辑 2：查看后发现，pavucontrol即使耳机已插入，它也会认为耳机未插入。它似乎将耳机视为扬声器的延伸，因为当我更改“扬声器”音量时，alsamixer它也会通过耳机更改音量。
编辑 3：输出$ pacmd list-sinks

答案1
首先，保持选项snd-hda-intel model=asus-mode5添加到/etc/modprobe.d/alsa-base.conf
禁用 pulseaudio 的自动生成功能并终止所有实例
$ echo autospawn = no >> /etc/pulse/client.conf
$ killall pulseaudio
检查是否有其他东西使用声卡
$ sudo fuser -v /dev/snd/*
确保杀死出现的任何东西并阻止其重生，如何做到这一点将取决于程序本身。
安装alsa-tools-gui
$ sudo apt-get install alsa-tools-gui
$ sudo hdajackretask
当 GUI 加载时，单击“显示未连接的引脚”，将第一个未连接的引脚覆盖为耳机插孔并应用设置。守护 pulseaudiopuslseaudio -D并测试声音，对所有未连接的端口重复此操作，直到找到正确的端口。
找到正确的插孔后，单击“安装引导覆盖”并重新启动以确保一切正常。现在编辑pulseaudio配置文件并删除之前添加的行以允许再次重生。
除非您重新启动，否则只能使用alsamixer而不是通常的 GUI 组件来修改卷。重新启动后，一切恢复正常。
