The default module config has: +options snd cards_limit=1 I have no clue why we need to set limit by default but 1 seems a bit small for modern desktop systems. Here I do have 2 cards because of HDMI output on video card, and I think other desktops with real video card have the same.
I couldn't find an equivalent file in the packages for other distributions... I neither known where the original file comes from... maybe from an "alsaconf" run with default parameters :/ But I don't know how the other distros are handling the OSS compatibility... as the other parts are likely obsolete
Created attachment 842859 [details] ubuntu-alsa.conf I have been reviewing the config files on an Ubuntu 20.04 installation and it seems that, even if they also use a modprobe.d file, they specify completely different settings aiming to workaround some bugs. I think then that dropping the cards limit line could be safe (and probably dropping most of the lines too)
I am running for some days without any alsa.conf file and for now it works... I would drop it then and, if we need to add lines in the future, add them with the proper references as done in Ubuntu
