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.
