Arch Linux中的音频

Question

我已经有一段时间在Arch Linux中出现音频问题了.在这里:

当我将耳机插入启动时,Arch将通过我的耳机播放所有音频,当我将它们插入时,没有声音.Arch只会通过我的耳机播放音频.当我没有插入它时,Arch只会通过扬声器播放声音.

Doeas任何人都知道如何解决这个问题所以我不需要重新启动来更改我的音频输出设备？

在Macbook Pro 7,1上提前收到关于我的Arch Linux的一些信息:

我忘了说:我将Xfce4作为桌面环境.

Answer 1

首先,检查您是否安装了音响系统.打开您喜欢的终端并输入:

$ pacman -Qs | grep "alsa"

它应该是默认安装.

如果命令输出为空,则表示您没有声音系统.然后,您可以安装所需的那个.

Pulseaudio:

# pacman -Syu && pacman -S pulseaudio pavucontrol

使用

$ pavucontrol

更改所有音频输出和输入.您甚至可以根据客户端/服务器的原理将输出流重定向到麦克风和其他一些很酷的东西.

阿尔萨:

# pacman -Syu && pacman -S alsa-utils alsa-plugins

Alsa非常简单(但缺少一些功能)并且非常易于使用.它的模块直接包含在内核中,这意味着它可以在每个声音硬件上开箱即用.您可以通过发出以下命令来更改音频输出:

$ alsamixer

这将提示一个漂亮的基于终端的界面.从那里,我建议你将所有通量提高到100%(到每个顶部).

xfce4声音小程序应该可以正常工作.如果没有,您可以下载一个简单的音量控制:

# pacman -Syu && pacman -S volumeicon

您可能需要对Xstartup文件进行一些更改才能添加volumeicon applet.

如果你遇到任何麻烦,请告诉我.

Answer 2

我不知道你使用什么样的桌面环境。但你可以这样做：

1. 开机时尽量不要插耳机
2. 如果你使用gnome，可以打开设置->声音->输出->选择声音输出设备，然后选择合适的设备。
