In Vanilla, you're usually working inside a container.
To change stuff around the base system or the kernel, you need to use "host-shell".

In this case it would be
host-shell pkexec nano /etc/modprobe.d/alsa-base.conf

(pkexec is an alternative to sudo since we don't install sudo by default on the host system)

But yeah, we also don't ship this file.
You can create it though and just add the options, it should work either way.
