570 [ 54.901911] hda_codec: Unknown model for ALC883, trying auto-probe from BIOS...
So it looks like Linux has to consult the BIOS in order to recognize that particular ALC883 chip.
BTW the Wikipedia entry for
Intel High Definition Audio reveals:
Quote:
Intel High Definition Audio (also called HD Audio or Azalia) refers to the specification released by Intel in 2004[1] for delivering high-definition audio that is capable of playing back more channels at higher quality than previous integrated audio codecs like AC'97. During development it had the codename Azalia.

So that is the origin of the
azalia name.
If you only installed 5.2 recently and thus is it not much a hassle to backup your stuff, you could try the latest snapshot
ftp://ftp.openbsd.org/pub/OpenBSD/snapshots/i386/
This snapshot is very, very close to what will be OpenBSD 5.3 which will be released on May 1st 2013.
If this snapshot also does not give you sound, you could ask on the OpenBSD misc mailing list, but be aware that the developers are very busy right now with the 5.3 release, so don't be disappointed if they do not have the time to answer or assist you in this matter right now.
