Not to be dismissive, but I have. I've tried instructions from my laptops "parent" and "brother" units and the instructions don't work. I've spent an hour or two on this at different times and I know everyone says this, but I usually always figure this type of thing out when I get stuck on it. I've tried Arch wiki, Ive been through some LKML threads, some long RH bug, etc. I can actually see in my NixOS config other attempts I've made previously. I've even tried custom snd.conf, doing things in Windows, etc. A bit crushing at this point, I just grabbed a spare set of BT earbuds that are probably just as fine a solution. (Until I accidentally boot to windows and realize how decent it can sound)
