我买了一台 Intel Core i3 4130 和一块 Gigabyte H87N-WIFI 主板，打算打造一台 HTPC。我正在实时 USB 上试用 Ubuntu 13.10，除了 5.1 环绕声音频外，一切正常。
测试单个扬声器时出现此错误：关联
前左、右、中置和 LFE 在其正确的扬声器中播放，但后左和后右分别在前左和前右播放。当我选择数字立体声时，音频播放正常。
我可以使用数字光纤 S/PDIF 播放，但由于某种原因它似乎不支持 5.1，并且我的环绕系统不支持混合 HDMI 视频和光纤音频源。
我几乎找遍了所有地方，但还是没能找到遇到过类似问题的人。如果您有任何建议，请随时提出！

答案1
我在 12.04 上安装了 3.13.3 内核，从那时起它就运行良好。我不太了解破解方法，因此无法确定是否可以改进它，或者是否建议将其用于生产系统。但它也解决了我在 HDMI 方面遇到的另一个问题。
