I didn't know that I can give multiple files, so I haven't tried. One
minor problem with this approach is that the alsa.conf path would be
hardcoded, instead of using $(datadir)/alsa.conf.

Yes, but did you miss the part entirely where I load alsa.conf in the
beginning of the custom configuration file? That should work too, right?

I know that alsa.conf is being loaded, because if I comment out the part
that loads alsa.conf, I indeed get an error saying that "sysdefault" is
not defined.
