我是 Linux 新手，使用 Linux 多年，但我只是个基础用户。我认为我的下一步是尝试安装/配置 pipewire。但我真的不确定这是驱动程序问题，还是 pulseaudio 和 alsamixer 的配置问题。
2023 年 12 月 19 日更新：安装 pipewire 并未解决问题。我在启动时也一直收到“检测到系统程序问题”的提示，但没有其他详细信息。不确定问题是否相关。

答案1
我已经用以下命令解决了这个问题：
$ sudo -i
# echo "options snd-hda-intel model=generic" | tee -a /etc/modprobe.d/alsa-base.conf
# echo "options snd-hda-intel dmic_detect=0" | tee -a /etc/modprobe.d/alsa-base.conf
# echo "blacklist snd_soc_skl" | tee -a /etc/modprobe.d/blacklist.conf
# apt-get install --reinstall alsa-base pulseaudio
# alsa force-reload
# apt purge timidity-daemon
# reboot
