Ubuntu 22.04下Intel Comet Lake声卡耳机无声音问题求助

各位大佬好！我是刚接触Ubuntu的新手，最近装了Ubuntu 22.04.3 LTS x86_64桌面版，遇到了耳机没声音的问题，折腾了半天终于解决了，把方法和之前的排查信息分享出来，希望能帮到同样踩坑的朋友！

已解决方法 #

编辑：我通过打开alsamixer里的所有设置解决了问题——把所有显示MM（静音状态）的选项都改成00（取消静音）就可以了！

问题背景 #

一开始装完Ubuntu后音频有问题，查资料知道需要安装sof-bin，装完之后虽然dummy output消失了，但耳机还是没法正常输出声音，我就想搞定这个耳机音频的问题，不想再来回切换Windows了（真的更爱Linux）。
