仍然是pam升级后的错，解决普通用户无声音的问题
pam现用版本对比pam0.8-3mgc，在/etc/security/console.perms.d/50-default.perms里发现明显差异，MGC的声音定义名称是sound，我用别的名字没成功过，有兴趣的朋友可以尝试。解决办法，重新打包pam，并重写定义 /etc/security/console.perms.d/50-default.perms
不想等待升级的朋友请把以下内容复制替换 /etc/security/console.perms.d/50-default.perms

我已经解决了普通用户无声音的问题，谢谢版主:shock: :-D 噢，那fuse应该也和这个有关了。
