HDMI板载声音可以工作，但没有模拟声音
我最近在我的电脑上安装了Ubuntu 12.04，但没有声音。
我的电脑主板是英特尔，它有VGA，DVI和HDMI输出，所有这些都是板载的。 但我在其上安装了一个带有另外三个VGA，DVI和HDMI输出的外置PCI-e nvidia显卡。 我的显示器已插入nvidia卡的DVI端口，因此两个HDMI端口均未使用
这是命令“aplay -l”的结果：

有人有类似的问题吗？
编辑：解决了我的问题。 我的音板上的模拟声音在BIOS上被禁用。 激活后，一切都很好。
我有同样的卡。 它在11.04工作正常（不确定是否需要任何修复），但我在安装12.04后努力让它工作。 找到了一个有效的解决方案： https ： //bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/703464
打开此文件：
/etc/modprobe.d/alsa-base.conf
并将此行添加到底部：
options snd-hda-intel model=generic
然后，重新启动计算机。 希望这可以帮助。
