I'm having this problem that I lose sound when I restart my computer (It's a system76 box with system76's kernel and goodies). I checked this page https://support.system76.com/articles/audio/ and the problem is solved by running sudo alsa force-reload, but I have to do it every time I'm already on my kde session (I installed kde-full). Is there a way to avoid me from having to do it every time?
As a little update, when I run alsamixer (even when I get no sound on kde), it displays the sound card:
