Ok thanks, I'm now following that guide and I'm getting closer. The problem 
here is that if I have this in my /etc/modprobe.d/alsa-base.conf 

options snd-aloop index=0 pcm_substreams=2

then I get

# modprobe snd-aloop
ERROR: could not insert 'snd_aloop': No such device

but it works if I omit the options in /etc/modprobe.d/alsa-base.conf. Please 
note that I've already tried rebooting several times with and without the 
options in place, same result.

Moreover, if I

# alsa force-unload

In /var/log/dmesg.log I have

What am I doing wrong?
