如何解决 2017 MacBook Pro（基于 Intel）上的“虚拟输出”问题？目前，声音无法正常工作，当我尝试增加（或减少）音量时，我看到“虚拟输出”作为输出设备。

我发现了一个类似的问题：2017 iMac Pro 上的虚拟输出和无输入设备，修复方法是使用https://github.com/egorenar/snd-hda-codec-cs8409（用于 Cirrus Logic CS8409 的 Linux 内核声音驱动程序（例如用于 iMac27 5k）），它有 6 个未解决的问题并且已经 2 年没有更新了。

还有https://github.com/davidjo/snd_hda_macbookpro（适用于配备 8409 HDA 芯片 + MAX98706/SSM3515 放大器的 Mac 的内核音频驱动程序），该驱动程序最近才维护（5 个月前），但不是官方的，有 62 个未解决的问题。这是我最好的选择吗

更新：我安装了snd_hda_macbookpro，现在看到的是“耳机”而不是“虚拟输出”，但仍然没有声音。

更新 2：我安装了snd-hda-codec-cs8409（通过运行make并make install在 repo 目录中），但仍然显示“耳机”并且我听不到声音。

问题：

在启动 Ubuntu 24.04 LTS 时，笔记本电脑的音频只有 10 次中有 1 次可以正常工作。我要么使用“ HDMI/Display 端口”（使用这个端口，来自外部显示器耳机插孔的音频可以正常工作），要么使用正常的笔记本电脑音频（声音来自笔记本电脑的内置扬声器）。当我插入外部显示器启动时，大多数时候我都会得到“HDMI/Display 端口”。此外，在没有外部显示器的情况下启动时，大多数时候都会得到“虚拟输出”，笔记本电脑的内置扬声器和耳机插孔都无法正常工作。

但是，无论哪种情况，蓝牙音频都可以正常工作，没有任何问题。

我想要实现的是一个功能一致的笔记本电脑内置扬声器。

到目前为止我已经尝试过：

  1. alsa-base.conf在located in中添加以下具有不同组合的行/etc/modprobe.d：

    options snd-hda-intel model=dell
options snd-hda-intel model=generic
options snd-hda-intel model=clevo-p950
options snd_hda_intel index=0,1 id=PCH,HDMI

  2. 使用以下命令重新启动 PulseAudio：

    systemctl --user restart pulseaudio

  3. 类似问题中提到的无数其他调整。

  4. 使用 Windows（安装在单独的磁盘中）交叉验证了音频中是否存在任何潜在的硬件问题。音频每次都运行良好，因此排除了硬件问题。

  5. 使用主线内核尝试了其他内核。

将 Ubuntu LTS 从 jammy 升级到 24.04 noble 后，登录时会长时间挂起，并且会在黑色背景上出现一个可移动的白色指针，然后会出现一个图形消息，提示系统在我的配置文件中“无法获取接收器信息”，可能与某些音频驱动程序有关，但除了“应该修复它”之外没有其他有用的详细信息。

警告

加载 /home/ingo/.profile 时发现错误：

无法获取接收器信息：没有这样的实体

因此会话将无法正确配置。您应尽快修复此问题。

好的

有人知道这个消息以及如何修复吗？

升级到 24.04.01 LTS 后，没有可用的音频设备（既没有扬声器也没有麦克风）。

我尝试使用以下方法进行调试：

sudo dmesg | grep -i alsa
sudo dmesg | grep -i snd
lspci | grep -i audio
aplay -l

和：

$ systemctl --user status pulseaudio
Unit pulseaudio.service could not be found

（没关系，24.04 使用 pipewire）

systemctl --user status pipewire-pulse
systemctl --user status  wireplumber

一切都很好。

这里有一个问题：

由于某种原因，我无法通过笔记本电脑扬声器播放音乐或任何音频，但如果我插入任何其他扬声器或蓝牙扬声器，它就可以正常工作。我看到某个地方需要卸载并重新安装我的音频驱动程序，所以我这样做了 pipewire、alsa 和 pulseaudio，但这不起作用。

我在其他地方看到过一个修补程序，即将内核降级到 6.5，但是我对 Linux 生态系统还不太熟悉，所以我对这样做有点犹豫。

我正在使用 Ubuntu 24.04 6.8.0.45 通用版。

从 Ubuntu 24.04 开始，我找不到关闭 Bose 耳机的耳机模式的方法。

在较旧的 Ubuntu 版本中，在“设置”中，我可以选择将耳机用作 A2DP 或耳机模式。但是，在 Ubuntu 24.04 中我不再有此选项。我只得到一个“免提”选项，如果我选择该选项，我只能在耳机模式编解码器之间切换。

在此处输入图片描述

我遇到了与此问题中描述的完全相同的问题：耳机声音输出与线路输出混合。不幸的是，这个问题没有发布答案。我不确定以这种方式发布问题是否合适（我是这些论坛的新手），但我已经尝试了几个星期来解决这个问题，但没有成功。

我遇到此问题的系统使用带有三个模拟输出的 CS4207。三个输出中只有两个连接：耳机和线路输出。我在 Windows 上测试了音频硬件，并验证所有硬件均按预期运行（这和我进行的其他一些测试使我相信这是 Alsa 或 pulseaudio 的驱动程序问题）。

我看到的问题如下：当选择 Line Out 作为声音输出时，声音按预期工作（即，声音仅来自连接到 Line Out 端口的扬声器），但是当选择 Headphones 作为声音输出时，声音来自连接到 Headphones 端口的扬声器和连接到 Line Out 端口的扬声器。

通过 Alsamixer 查看声音设置同时更改所选的输出设备有助于说明问题。

当选择 Line Out 为输出时：

LineOut_selected_output

当选择耳机作为输出时：

耳机_选定_输出

正如您在此处看到的，当选择 Line Out 为输出时，耳机会自动静音并将音量设置为零，但是当选择 Headphones 为输出时，Line Out 音量和静音设置不会受到影响。

为了解决这个问题，我一直在进行修改/usr/share/pulseaudio/alsa-mixer/paths/analog-output-headphones.conf，虽然我可以看到更改正在应用（声音设置更改和 alsamixer 更改），但我还没有找到具有预期效果的修改。

我不确定下面的任何内容是否有用，但我将重现原始帖子中生成的输出，这些输出指出了这个问题（以下输出来自我的系统，我只是运行与原始帖子相同的命令）。请注意，在运行这些命令之前，我已将所有修改恢复到 analog-output-headphones.conf。

该设备是 Maono Maonocaster C2 Neo。Ubuntu 24.04。

当通过 JACK 服务器路由时，我可以使用 Audacity 选择输入和输出的设备，但不能将其用于一般系统音频。

这是它在与 USB 设备一起列出时显示的样子。

有没有办法强制 Pulse“看到”该设备并让我选择为系统输入/输出？

我目前正在使用 Ubuntu 24.04，但我在版本 22 中也遇到了这个问题。当我连接我的蓝牙耳机（Soundcore P3）时，它只播放单声道，设置中唯一可用的配置是：-HSP/HFP -HSP/HFP 编解码器 CVSD -HSP/HFP 编解码器 mSBC

我几乎尝试了所有能找到的解决方案，但都无济于事。有没有其他人遇到过这个问题并成功解决了？任何帮助都将不胜感激！

之前有一篇帖子提到了类似的问题，答案建议关闭输入通道以允许 A2DP。我试过了，但问题仍然存在，我仍然只有上述这 3 个配置……

附言：我将我的耳机在不同的系统上使用（例如 Android、iPad、Windows、其他发行版如 fedora），并且运行良好，没有任何问题。
