华硕：扬声器和耳机同时播放音频

在我的华硕电脑上，使用 Kubuntu 14.04，如果我插入耳机，音频仍会从两个输出（扬声器和耳机）播放。我可以在启动后使用 alsamixer 或 Phonon 手动修复此问题，但这很烦人。我知道这是一个新问题，它已在 16.04 版本中修复，但我无法升级到此版本。那么，我该如何解决这个问题？

我尝试过的解决方案（没有成功）：

  • 编辑 alsa-base.conf：

回显“选项 snd-hda-intel 模型 = 自动”| sudo tee -a /etc/modprobe.d/alsa-base.conf

    echo "options snd-hda-intel model=asus" | sudo tee -a /etc/modprobe.d/alsa-base.conf

    echo "options snd-hda-intel model=laptop" | sudo tee -a /etc/modprobe.d/alsa-base.conf

    echo "options snd-hda-intel position_fix=1 enable=yes" | sudo tee -a /etc/modprobe.d/alsa-base.conf

    echo "options snd-hda-intel model=generic" | sudo tee -a /etc/modprobe.d/alsa-base.conf

（不在一起）
