有一天，我的耳机坏了，当时使用的是戴尔 precision m4800 笔记本电脑。我想我以前也遇到过这种情况
sudo apt-get update && sudo apt-get upgrade
然后重启后它就死机了。扬声器的声音正常工作。查看了论坛上的一些帖子，这些帖子描述了将 pulseaudio 设置重置为默认值等。这些都没有帮助。
lspci -v | grep -i audio 的输出
00:03.0 Audio device: Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor HD Audio Controller (rev 06)
Subsystem: Dell Xeon E3-1200 v3/4th Gen Core Processor HD Audio Controller
00:1b.0 Audio device: Intel Corporation 8 Series/C220 Series Chipset High Definition Audio Controller (rev 04)
Subsystem: Dell 8 Series/C220 Series Chipset High Definition Audio Controller
在 /etc/modprobe.d/alsa-base.conf 中也添加了
options snd-usb-audio index=-2
options snd-pcsp index=-2
alias snd-card-0 snd-hda-intel
alias sound-slot-0 snd-hda-intel
options snd-hda-intel model=auto
正如某人提到的，并没有帮助。
aplay -l 的输出

有人可以提示我该怎么办吗？因为似乎没什么帮助？
谢谢
