在我安装 Skype 后，发生了这种情况Ubuntu 18.04.4 LTS。我发现 Skype 没有声音，所以我搜索了解决方案。有人建议安装pavucontrol
sudo apt install pavucontrol
此后，它并没有解决我的 Skype 问题，反而导致我的笔记本电脑失去音频输出。
我尝试了网上的很多解决方案，但都不起作用。以下是我已经尝试过的解决方案。
# solution 1
pulseaudio -k && sudo alsa force-reload
# then I did
pacmd list-cards
# which gives me
0 card(s) available.
# I also tried
aplay -l
aplay: device_list:270: no soundcards found...
#solution 2
sudo apt-get update
sudo apt-get dist-upgrade
sudo apt-get autoremove
sudo killall pulseaudio
rm -rf ~/.config/pulse
pulseaudio -k
我尝试了这些并重启了我的笔记本电脑。但都不起作用。我的笔记本电脑是hp spectre x360。有什么建议吗？非常感谢！

我运行了 alsa-info 脚本这里。这就是我得到的：

答案1
好的，我搞定了。感谢 Jean 的帮助。
我在这里使用解决方案解决方案。
打开/etc/modprobe.d/alsa-base.conf并在末尾添加以下行：
options snd-hda-intel dmic_detect=0
然后：
pulseaudio -k && sudo alsa force-reload
你会听到声音。
答案2
对我而言唯一有用的方法是使用命令更新内核sudo apt update && sudo apt upgrade。有关更多信息，请参阅此链接。
答案3
更新后遇到同样的问题。
您可以使用以下命令显示音频设备以及正在使用的内核模块/驱动程序：
lspci -nnk | grep -A2 Audio
我得到了类似这样的信息：
00:1f.3 Audio device [0403]: Intel Corporation Device [8086:9dc8] (rev 11)
Subsystem: Lenovo Device [17aa:2292]
Kernel driver in use: snd_soc_skl
第二种方法邮政解决了我的问题：添加blacklist snd_soc_skl到末尾/etc/modprobe.d/blacklist.conf。
