 The hdaudio(4) mixer is built with the OSS mixer APIs in mind. In this
 particular case, it is not handling the AD1989B correctly, and may be
 indicative of another issue.
 
 If hardware volume controls are truly not available, I do plan on adding
 software volume support using auconv so from the user POV it doesn't matter.

 That's not really relevant.  It's the same old OSS mixer API vs. NetBSD
 mixer API.  I had checked in code long ago to make AC97 behave better in
 that particular situation (although that introduced some weird behaviours in
 other, much less frequent, situations), and I think it eventually found its
 way to azalia.
 
 Either the NetBSD API gets changed to be stateful and thus have a chance to
 support OSS properly (but that's not ideal either), or a similar hack has to
 be introduced for hdaudio(4).
