HDMI 板载声音可用，但没有模拟声音

我最近在电脑上安装了 Ubuntu 12.04，但是没有声音。

我的电脑主板是英特尔的，它有 VGA、DVI 和 HDMI 输出，全部都是板载的。但我在它上面安装了一个外部 PCI-e nvidia 显卡，还有另外三个 VGA、DVI 和 HDMI 输出。我的显示器插在 nvidia 卡的 DVI 端口上，所以两个 HDMI 端口都未使用

以下是命令“aplay -l”的结果：

我知道，理论上 HDMI 声音是可以工作的。但我需要模拟声音，因为我的显示器没有 HDMI 端口。以下是 lspci 命令的结果：

有人遇到过类似的问题吗？

编辑：解决了我的问题。我的音效板上的模拟声音在 BIOS 上被禁用。激活后，一切正常。

答案1

我有同样的卡。它在 11.04 中运行良好（不确定是否需要任何修复），但在安装 12.04 后，我很难让它工作。在这里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

并在底部添加这一行：

options snd-hda-intel model=generic

然后，重新启动计算机。希望这有帮助。

首先，你需要检查 aplay 是否真的可以播放这个 wave 文件。你可以运行命令“aplay -D plughw:CARD=PCH,DEV0 [wav file]”。如果成功，则问题是由 pulseaudio 引起的。

这是 pulseaudio 上的解决方案。运行“aplay -l”以转储接收器。

$ aplay -l

“hw:0,0”是模拟设备。

运行“arecord -l”来转储源。

$ arecord -l

“hw:0,0”是模拟设备。

现在，让我们在 pulseaudio 中静态启用它们。编辑“/etc/pulse/default.pa”。

load-module module-alsa-sink device=hw:0,0
load-module module-alsa-source device=hw:0,0

这两行应该位于诸如“.ifexists module-udev-detect.so”之类的代码上方。然后运行“pulseaudio -k; pulseaudio --start”以重新启动 pulseaudio。它现在应该可以工作了。
