So what these two lines do is assign the speaker (nid20) and headphone
(nid33) pins to the same association ("as", i.e group). In the second
line, "seq=15" means that the headphone pin will duplicate (and
automatically mute if not plugged) the first pin in that association. In
other words, the output will switch from the speakers to the headphones
if headphones are plugged in, and vice-versa. The snd_hda(4) man page
explains what "as" and "seq" are.
