Ubuntu 安装后没有声音

在硬件机器上用wubi安装了ubuntu

description: Desktop Computer
    version: Lenovo Product
    width: 32 bits
    capabilities: smbios-2.5 dmi-2.5 smp-1.4 smp

但是在安装好后，声卡无法工作，结果就开始网上寻找解决方法。

我这在sound performance中但硬件hardware上看不到声卡，所以，我还以为我没有安装上声卡，

但所在用alsa，命令后，Usage: /sbin/alsa {unload|reload|force-unload|force-reload|suspend|resume}

所以 我就用 alsa force-reload后，以为能强制加载上驱动，但是，结果总不算让人满意但

lsof: WARNING: can't stat() fuse.gvfs-fuse-daemon file system /home/liu/.gvfs

这就算强制加载声卡驱动但结果，驱动加载了

但是，柳暗花明，看见有大神说可能所自己没有神卡使用但权限

这样看一下，看把，
