一点声音都没有……
检查了所有驱动程序和声卡，全部安装正确。通过 ubuntu 表单检查，但旧解决方案（在 alsa.conf 中将选项 snd-hda-model 添加到 lenovo sky）不起作用。我的内置音频设备正在显示（也在脉冲音频控制中）。没有显示任何错误。此外，如果我插入耳机，会播放一点声音，但听不懂，只是节拍，而且太不清楚。
这是联想 Ideapad Y510 -2008 型号，仅运行在 Ubuntu 13.10 上

还尝试了 Wyth 的解决方案http://ubuntuforums.org/showthread.php?t=870681&page=15 但我猜它很旧了，而且我所有的驱动程序都已经正确了。并且sudo alsa force-reload也不起作用。
