22.04 LTS 无声音 - 英特尔声卡 snd_hda_intel 无法识别

我在笔记本电脑上安装了 Ubuntu 22.04 LTS，虽然一切运行正常，但我的电脑没有声音。

对我来说，解决方案是从这里安装最新的 Sound Open Firmware (SOF) 二进制文件：https://github.com/thesofproject/sof-bin

具体来说：

  1. 克隆存储库：git clone https://github.com/thesofproject/sof-bin.git
  2. 更改目录：cd sof-bin
  3. 跟随：https://github.com/thesofproject/sof-bin#install-process-with-installsh（对我来说 v2.2 有效）
sudo mv /lib/firmware/intel/sof* some_backup_location/
sudo mv /usr/local/bin/sof-*     some_backup_location/ # optional
sudo ./install.sh v2.2.x/v2.2
  1. 重启

此后，声音输出和麦克风都可以正常工作（Ubuntu 23.04，联想 X1 Gen8）

注意：请确保 或中未设置snd_hda_intel.dmic_detect=0或设置。否则声音输出可能有效，但没有麦克风输入。snd_intel_dspcfg.dsp_driver=1GRUB_CMDLINE_LINUX_DEFAULT/etc/modprobe.d/alsa-base.conf
