我有声音问题。我刚刚安装了12.04 64 位，而且声音太差了，尖峰关于声音（youtube、mp3、avi...），比如 CD 有划痕。在设置中analog output。analog stereo duplex我认为这个问题只出现在 12.04 和 linux mint 13 上
这是我的卡信息：

我的扬声器是黑色插孔。
我该如何解决这个问题？谢谢
答案1
编译驱动程序
去Realtek 官方网站，接受免责声明，然后下载适用于 linux/unix 的音频驱动程序。对于内核 3 或更高版本，您需要选择版本 3。
设置必要的工具来编译该驱动程序。
sudo apt-get install build-essential gcc make解压下载的文件，
./install进入解压的文件夹后从终端运行文件来编译驱动程序。阅读
Readme.txt文件以了解更多信息。
我在 Ubuntu 12.04 中遇到了声音设置问题。现在已修复
解决方案 2
我刚刚找到了另一个解决方案：
（对我来说，它仅适用于 S/PDIF 配置文件，耳机和扬声器都有声音，并且无法切换配置文件）
通过命令添加此 ppa
sudo apt-add-repository ppa:ubuntu-audio-dev/alsa-daily
2，更新软件包列表。
sudo apt-get update
- 然后安装“alsa-hda-dkms”包：
sudo apt-get install alsa-hda-dkms。
重新启动，查看结果！
