Ubuntu 22.04升级后内置麦克风无法被检测的问题求助

大家好，我最近把系统从Ubuntu 20.04升级到22.04后，遇到了内置音频设备的问题——一开始输入和输出设备都没被系统检测到。我尝试了某个升级后无声音输出设备的帖子里的所有方案，最后通过在/etc/modprobe.d/alsa-base.conf里添加options snd-hda-intel dmic_detect=0解决了内置扬声器的问题，但内置麦克风仍然无法被检测到。

可以排除硬件故障，因为这个麦克风在Windows 11、Ubuntu 20.04，甚至Ubuntu 22.04的Live环境里都能正常工作。

已尝试但无效的解决方案 #

• 完全重装alsa和pulseaudio：

sudo apt-get remove --purge alsa-base pulseaudio
sudo apt-get install alsa-base pulseaudio
sudo alsa force-reload

• 重启pulseaudio实例：

pulseaudio -k
pulseaudio -D

• 重启pulseaudio服务：

systemctl --user restart pulseaudio.service
systemctl --user restart pulseaudio.socket

• 替换为pipewire替代pulseaudio：

sudo apt install pipewire-audio-client-libraries
systemctl --user stop pulseaudio.service
systemctl --user stop pulseaudio.socket
systemctl --user disable pulseaudio.service
systemctl --user disable pulseaudio.socket
systemctl --user start pipewire.service
systemctl --user start pipewire-pulse.service
systemctl --user enable pipewire.service
systemctl --user enable pipewire-pulse.service

• 删除pulseaudio配置文件：

rm -r ~/.config/pulse

• 重置pipewire与pulseaudio的关联：

sudo touch /usr/share/pipewire/media-session.d/with-pulseaudio
systemctl --user restart pipewire-session-manager

有没有大佬能给点解决思路？谢谢大家了！
