The module's options are likely at least a start toward the solution. Here's an anonymized version of what I had in /etc/modprobe.conf when I used the loopback soundcard: options snd_aloop enable=1,1,1,1,1,1,1 index=4,5,6,7,8,9,10 id=lbuser1,lbuser2,lbuser3,lbuser4,lbuser5,lbuser6,lbuser7 Depending on your distribution, you might need to put the options in a different path/file. Fwiw, I found a problem with Debian 7/Wheezy's snd_aloop in connection with [Net]Jack. The virtual soundcard would accept playback samples much faster than a real soundcard would have, which resulted in xruns.
