从 12.04 全新安装到 Ubuntu 12.10,现在声音不起作用。在 12.04 中,声音开箱即用。
我跑了hwinfo --sound
hal.1: read hal dataprocess 4222: arguments to dbus_move_error() were incorrect, assertion "(dest) == NULL || !dbus_error_is_set ((dest))" failed in file ../../dbus/dbus-errors.c line 282.
This is normally a bug in some application using the D-Bus library.

不确定如何修复此问题。在此版本之前也可以使用。

到
/etc/modprobe.d/blacklist.conf
(重启)
声音现在可以正常工作并且“虚拟输出”已被真实声卡取代。

我个人发现这很有用:
