Yes, I am quite sure.  I am aware of the trick of specifying the model
in modprobe.conf (or modprobe.d/alsa-base) but it didn't work in this
case.  

The nice thing is that with these newer drivers, that model=acer line is
not required for sound to work.

I do have a link to my page, where I mention the model=acer trick.  I
think that's a great idea to add mention of possible parameters, but
should probably be in a separate page about sound.  (I don't feel
capable of writing such a page--my sound needs are pretty basic, and I'm
no expert on it.  Something with a link, as well as telling the reader
how to apply these parameters, for example, in /etc/modprobe.conf, would
certainly be useful, however.)
