在 Ubuntu 服务器（64 位）上安装 Lubuntu-desktop 后我遇到了问题。
问题是，如果不进行可怕的黑客攻击，我无法让我的 X-Fi 外置 USB 声卡工作，而且即使这样，它也只能在某些应用程序中工作。
我目前只能使用 ~./asoundrc 中的以下 hack 在 VLC 媒体播放器中播放媒体
pcm.!default {
type hw
card 1
}
ctl.!default {
type hw
card 1
}
这可以按预期工作，但对于许多应用程序来说并非如此（无法启动，并显示与以下内容相关的错误消息（没有混频器控件））
┌──────────────────────────── AlsaMixer v1.0.24.2 ────────────────────────────┐

我可能遗漏了什么？一些诊断信息（任何其他信息可根据要求提供）：

首先，删除你的黑客程序，否则你会遇到越来越多的问题。

实际上，我已经在 Ubuntu 下很好地驯服了我的 X-Fi Titanium。我甚至写了一篇关于它的文章来帮助我记住每次我弄坏它、ubuntu 更新或重新安装 linux 时如何修复它。
祝你好运！ ：）
