   Not sure of a way to have it attach the audio driver to the sound 
device but not get /dev/dsp entries. I think people used to `kldload 
snd` to have it load a whole series of audio modules onto detected 
hardware but I doubt that matters since it says snd_hda (built into the 
kernel) already is attached if I am reading that correctly.
   I know the sound system has actively received changes lately so you 
may find differing results with both older and newer FreeBSD versions. 
Some changes have been within the past week so up to date 14-stable code 
is different from your codebase that is over 2 weeks old but I don't 
know that any of those changes should fix such an issue.
   As you are using -stable, there is also a mailing list more focused 
on that but I don't know if its attention will matter here or not; 
definitely would be more appropriate if -release worked but -stable broke.
   If no one else comes up with ideas and you don't find a problem 
report for this, it mat be beneficial to make one.
