戴尔 XPS + 坞站 WD19 - 扬声器不工作

Tom*_*ski 5 sound pulseaudio dell alsa

我的扬声器通过插孔连接到坞站 Dell WD19 时遇到问题。似乎检测到输出，但没有播放声音。

卡 1 上的两个输出似乎是扩展坞正面和背面的插孔 - 其余的是内置扬声器、监视器和 USB 连接的耳机。

现在，当我打开声音设置时，我可以看到许多设备：

声音设置

当我选择任何无线立体声耳机时，HDMI 2 或内置扬声器的适当设备确实会发出声音。但是当我选择 USB 音频（耳机或线路输出）时，一切都很安静——即使音量设置为 100%。我的想法不多了，我还能检查什么来解决这个问题......

（当我切换到 Windows 时，完全相同的设置工作正常，所以这不是硬件问题）

我在这里建议尝试一些事情。有些是从旧线程/解决方案/等中获取的，因此它们可能不适用。

  1. 这（发出命令后重新启动）

    killall pulseaudio
rm -r ~/.config/pulse/*
rm -r ~/.pulse*
    Run Code Online (Sandbox Code Playgroud)

  2. 安装pavucontrol并修改其控件。我不确定你会在那里看到什么。

  3. 这：“将“脉冲音频音量控制”中的配置从“模拟双工”更改为“数字立体声（IEC958）输出+模拟立体声输入”。 “查找类似的设置。

  4. 转到系统声音设置并将输出设置为线路输出（参考）（不确定您是否尝试过其他选择）

  5. 由于驱动程序似乎是，请尝试这样的snd_usb_audio解决方案，以某种方式适应您的情况。

作为答案发布的评论，否则不合适。

如果您发布以下输出可能会有所帮助：

$ cat /proc/asound/cards
$ lsmod | grep snd
$ dpkg -L linux-modules-<kernel version>-generic | grep snd
$ inxi -SA
$ lspci -nnk | grep -A 4 Audio
$ uname -a
$ dpkg -l | grep alsa
