升级到 Debian 测试后，PulseAudio 无法识别 Intel HDA (Buster)

772

从 Debian 9 stable 升级到 Debian 10 测试后，我在夏天注意到一个问题：PulseAudio 不再识别我的 Intel HDA 音频设备。当时我能够切换到通过 nVidia HDMI 连接的显示器音频，所以我回避了这个问题，希望未来的更新能够解决它。他们没有。快进几个月，我重新安排了我的工作空间，现在需要让英特尔 HDA 再次工作。

这是我到目前为止所看到的......

Debian 10 测试

内核看到它：

扬声器测试正常播放音频 aplay -D default:CARD=PCH /usr/share/sounds/alsa/Front_Left.wav

但是 PulseAudio 根本看不到该设备：

        device.class = "abstract"

当我进入声音设置时，我看到的只是虚拟输出设备。（此处不再列出 nVidia 设备，因为在重新排列时，我使用的是不同的显示器，没有音频，因此当前没有连接 HDMI 音频设备。）

我试图清除 PulseAudio 配置，认为我可能有一些遗留问题：

rm ~/.pulse/* ~/.config/pulse/*

Debian 9 稳定版

我在这台机器上有另一个分区，它仍在运行 Debian 9 stable，英特尔 HDA 在 PulseAudio 下工作，ALSA 驱动程序与 Debian 10 似乎确实存在差异，所以下面是我注意到的差异......

所以问题很明显：如何让英特尔 HDA 音频在 Debian 10 的 PulseAudio 中再次工作？这是我可以从配置的角度解决的问题，还是需要由 ALSA 或 PulseAudio 维护人员解决的驱动程序问题？

由于同样的问题，我最终来到这里，从 Stretch 升级后，音频消失了。类似的症状和输出（Nvidia 卡和 Intel HDA 声音）。但是，在按照说明进行操作时，我发现我无法执行此步骤：

root@desk:~# aplay -D plughw:0,0 /usr/share/sounds/alsa/Front_Center.wav
aplay: main:828: audio open error: Device or resource busy

我发现罪魁祸首是胆怯：

root@desk:~# fuser -v /dev/snd/*
                     USER        PID ACCESS COMMAND
/dev/snd/pcmC0D0p:   timidity   1274 F...m timidity
/dev/snd/seq:        timidity   1274 F.... timidity

一旦我杀了它，我就可以继续编辑/etc/pulse/default.pa，一切都到位了。我仍然不确定问题是缺少 PA 接收器还是胆怯接管。

我也考虑过提交错误报告，但我不确定哪里更合适。如果您有任何建议，我将很乐意听从您的建议，并在报告中加入我的支持。

感谢您分享解决方案！

我刚刚遇到了这个确切的问题，卸载 Timidity 解决了它。从字面上看，由于 apt 删除了软件包，我看到一条通知显示我有一张声卡（解释为音量变化）。

如果其他人遇到这种情况，这是强制 PulseAudio 使用 ALSA 设备的解决方法...

首先，通过 ALSA 直接播放一些音频，确认您知道正确的声卡和设备：

aplay -D plughw:<CARD#>,<DEVICE#> /usr/share/sounds/alsa/Front_Center.wav

就我而言，我想要光学音频输出，因此根据我aplay -l在上面的问题中看到的输出，它是：

aplay -D plughw:0,1 /usr/share/sounds/alsa/Front_Center.wav

记下卡和设备号并添加一个条目/etc/pulse/default.pa（将 0,1 替换为上一步中对您有用的）：

load-module module-alsa-sink device=plughw:0,1

我在文件中的.ifexists module-udev-detect.so行之前添加了这一行（即在### Load audio drivers statically 注释下方）

然后以您的桌面会话登录的用户身份运行以下命令（即不是以 root 身份）：

pulseaudio --kill
pulseaudio --start

然后您应该能够打开声音设置以查看并选择卡：

此时，您应该可以通过 PulseAudio 重新播放音频。（我注意到，即使它现在可以工作，它仍然pacmd list-cards不会列出该卡）提醒：这是一种解决方法，而不是长期修复，因此请务必记下自己以在将来的某个时间撤消此操作以查看如果它已正确修复。但它暂时使音频正常工作。

在 debian 9 到 debian 10 升级后，我只有一个虚拟接收器，没有任何音频

aplay -l失败，报告错误打开 99-pulse.conf

我/etc/alsa/conf.d/99-pulse.conf使用从 Xubuntu 安装中获取的内容创建：

# PulseAudio alsa plugin configuration file to set the pulseaudio plugin as
# default output for applications using alsa when pulseaudio is running.
hook_func.pulse_load_if_running {
    lib "libasound_module_conf_pulse.so"
    func "conf_pulse_hook_load_if_running"
}

@hooks [
    {
        func pulse_load_if_running
        files [
            "/usr/share/alsa/pulse-alsa.conf"
        ]
        errors false
    }
]

这解决了我的问题
