VLC indicates an access problem with OSS. What if you try
something that does not use OSS for output, for example
"madplay mpthreetest.mp3" or "mpg123 mpthreetest.mp3"?
There are other audio subsystems like EDS and SDL. Do you
have playback when you set VLC to use one of those?

That is very strange. The error messages show "libmad error" (MP3
decoder library) that probably interfaces with the sound subsystem.
Actually I have never seen this kind of error myself...

Maybe you should repair or repeat your installation. That manual
page should be present ("man 4 snd_hda" as well as "man 4 sound").

The easiest way would be to disable it using the mixer. Example:
% mixer
Mixer vol is currently set to 75:75
Mixer pcm is currently set to 75:75
Mixer line is currently set to 0:0
Mixer mic is currently set to 0:0 <--- silence
Mixer cd is currently set to 0:0
Mixer rec is currently set to 0:0
Mixer igain is currently set to 0:0 <--- maybe this
Mixer monitor is currently set to 0:0
Recording source: mic <--- maybe change that too
See "man mixer" for details.
