F30, Installing snd-dummy or virtual audio on headless server

I’ve been searching internet and found about snd-dummy sound module.
I can’t load it since it is not found. I can’t install it because I can’t find it.
I tried to add alsa virtual device but that need a real hardware also it seems.

How can I make a virtual sound card for my headless VPS?

Is modinfo snd_dummy show nothing (underliner, not -; for me works both ways)?

Try to

# kernel-modules{, extra, internal}
dnf install kernel-modules*

# also there was something like
# dnf repoquery --file /etc/lighttpd/lighttpd.conf
# --file snd-dummy.ko or --file *snd-dummy.ko ?

It is rather should present in Fedora Server kernel. If it isn’t, then there should be an “modern alternative”, and “you doin’ it wrong”, which is can be, idk.

Consider to search this page for “snd-dummy” (Kernel Docs).
