Gen*_*Rus 5 sound pulseaudio alsa 18.04
我的外部扬声器（通过耳机插孔）和监听扬声器（通过 displayport）在更新之前都可以工作，但我记得我第一次安装 Ubuntu 时不得不摆弄。自升级以来，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。
我已经尝试了互联网上提到的所有内容，但我似乎无法弄清楚出了什么问题，而且我觉得我已经用完了我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我无法找到和清除的配置文件。感谢您提供任何建议——我无能为力，只想看 Netflix ...... :)
我的/proc/asound/cards有以下几点：
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

所以我知道我的声卡在那里。我还确认在 alsamixer 中没有任何内容被静音。
aplay -l 产生：

我已经运行pulseaudio -k && sudo alsa force-reload，以及。
我已经尝试卸载并重新安装这里推荐的音频包： 声卡停止检测
我试过这里的一切，太：
没有声音在Ubuntu 18.04 LTS升级后从16.04 LTS
在pavucontrol没有卡的检测，所以我不能解除静音gnome-alsamixer。
我已经添加options snd-hda-intel model=auto到我的最后/etc/modprobe.d/alsa-base.conf。我建立了自己的计算机，也许还有比“自动”更好的东西？
我尝试删除snd_hda_intelwithpulseaudio -k && sudo service alsa-utils stop && sudo modprobe -r snd_hda_intel && sudo modprobe snd-hda-intel && sudo service alsa-utils start && pulseaudio -D但不能，因为它正在使用中。
我没有想法了。：/
