到目前为止，我已经花了大约 4 个小时来解决这个问题，并尝试了所有对其他人有用的常见解决方案。我第一次在升级到 22.04 时失去了声音，升级到 22.10 后仍然没有恢复。
以下是我尝试过的内容以及我见过的各种诊断命令的输出。
请帮忙！
尝试过的事情：
已尝试以下操作（在某些情况下尝试了多次）
sudo apt update
sudo apt upgrade
sudo apt dist-upgrade
sudo apt autoremove
sudo apt install update-manager-core
sudo do-release-upgrade
sudo touch /usr/share/pipewire/media-session.d/with-pulseaudio
systemctl --user restart pipewire-session-manager
sudo alsa force-reload
pulseaudio --kill
pulseaudio --start
sudo ln -s /usr/share/pipewire /etc/pipewire
sudo touch /usr/share/pipewire/media-session.d/with-pulseaudio
systemctl --user restart pipewire-session-manager
systemctl --user start pulseaudio
sudo apt install libldacbt-{abr,enc}2
sudo apt install libspa-0.2-bluetooth pipewire-audio-client-libraries pipewire-media-session
在 /etc/modprobe.d/alsa-base.conf 中尝试的选项
options snd-hda-intel dmic_detect=0
并且：
options snd-hda-intel model=generic
sudo vim /etc/default/grub
已更改：GRUB_CMDLINE_LINUX="" 至：GRUB_CMDLINE_LINUX="intel_iommu=on,igfx_off"
那么，当然：
sudo update-grub
reboot

答案1
好的，我刚刚通过将内核升级到 6.0 解决了这个问题。
谢谢 这个答案
答案2
正在做
sudo apt update
sudo apt upgrade
sudo apt autoremove
sudo apt install update-manager-core
和
sudo touch /usr/share/pipewire/media-session.d/with-pulseaudio
systemctl --user restart pipewire-session-manager
sudo alsa force-reload
解决了我的问题。
