Ubuntu 13.04没有检测到HDMI声音输出
所以，我已经升级到ubuntu v.13.04，但是，当我给这个播放时，我的HDMI声音输出正好工作……而且，HDMI声音设备不再出现在声音偏好上:(
当我运行lspci ：

那是输出……所以，我如何检测我的HDMI声音输出，并使用我的HDMI oudio？
我遇到了同样的问题。 以下链接帮助我解决了这个问题： http ： //ubuntuforums.org/showthread.php？t = 2139459＆page = 3＆p = 12621337＃post12621337
简而言之：
转到ALSA Launchpad并下载包： oem-audio-hda-daily-dkms*供您分发。 然后安装它并重新启动。
我没有你的硬件validation（我可以告诉你它在以前的硬件生成上工作正常）但是我知道我的NVidia HDMI音频在13.04上断了，同样的修复可能对你有用这个问题应该修复在下一次内核更新，同时主线内核（3.9rc8或3.8.8）应该修复它手动方式：
http://kernel.ubuntu.com/~kernel-ppa/mainline/
您将需要all.deb以及每个amd64.deb或i386.deb，具体取决于您使用32或64bit的天气
简单的方法：
如何添加主线内核PPA？
如果3.9rc8或3.8.8内核都没有为您修复，请将此标记为无用
3.9.0内核应该在几天内完成
