联想 Ideapad U430p 音频,驱动程序

我刚刚订购了联想 U430p,安装了 ubuntu 14.04。除了音频之外,一切都运行良好。虽然音频可以工作并且被系统检测到,但与 Windows 8.1(预装)相比,声音非常低。

答案1

  • 您的主要声音是第二个(第一个是 hdmi 声音),因此从软件中心(或sudo apt-get install pavucontrol)安装“脉冲音频音量控制”,并从多媒体菜单启动它。
  • 进入“输出设备”选项卡并设置最后一个设备的音量。
  • 更改最后一个右侧选项卡中的配置文件可能会有所帮助。
  • 您还可以alsamixer在终端中设置音量,然后按 F6 选择第二张卡,按右/左箭头选择推子,按上/下箭头设置音量,按 m 键取消静音/静音。
