在更新之前，我的外置扬声器（通过耳机插孔）和显示器扬声器（通过显示端口）都可以正常工作，不过我记得第一次安装 Ubuntu 时不得不摆弄一番。升级后，唯一显示的声音输出设备是来自我的 chrome-remote-desktop 的 Unix FIFO 接收器。

我尝试了互联网上提到的所有方法，但似乎无法找出问题所在，我感觉我已经用尽了在这里和其他地方找到的所有旧建议。正如您将在下面看到的，我的声卡存在，但不知何故未被系统/pavucontrol 检测到，所以我最好的猜测是有一些配置文件挂起，我无法找到并清除。任何建议都值得赞赏——我束手无策，只想看 Netflix... :)

我的/proc/asound/cards有以下内容：

0 [PCH            ]: HDA-Intel - HDA Intel PCH
                      HDA Intel PCH at 0xef630000 irq 39
1 [NVidia         ]: HDA-Intel - HDA NVidia
                      HDA NVidia at 0xef080000 irq 17

同样，lspci -v | grep -A5 -i "audio"说：

00:1b.0 Audio device: Intel Corporation 9 Series Chipset Family HD Audio Controller
    Subsystem: ASRock Incorporation 9 Series Chipset Family HD Audio Controller
    Flags: bus master, fast devsel, latency 0, IRQ 39
    Memory at ef630000 (64-bit, non-prefetchable) [size=16K]
    Capabilities: <access denied>
    Kernel driver in use: snd_hda_intel
    Kernel modules: snd_hda_intel

    Kernel driver in use: snd_hda_intel

所以我知道我的声卡在那里。我还确认 alsamixer 中没有任何东西被静音。

aplay -l生成：

pulseaudio -k && sudo alsa force-reload我也跑过。

我尝试卸载并重新安装这里推荐的音频包： 声卡不再被检测到

我也尝试了这里的一切： No sound in Ubuntu 18.04 LTS after upgrade from 16.04 LTS In pavucontrol no cards are detected so I can't unmute gnome-alsamixer.

I've added options snd-hda-intel model=auto to the end of my /etc/modprobe.d/alsa-base.conf also. I built my own computer and maybe there's something better than "auto"?

I tried removing snd_hda_intel with pulseaudio -k && sudo service alsa-utils stop && sudo modprobe -r snd_hda_intel && sudo modprobe snd-hda-intel && sudo service alsa-utils start && pulseaudio -D but couldn't because it was in use.

I'm out of ideas. :/
