:( 

What about the onboard Intel chip? Can you disable that?

The driver is binding to both.

I'm no expert on the sound subsystem, so I can't tell you.

You can probably get what you've got to work but I don't know the
appropriate magic.

I think you're probably best off posting to:

freebsd-multimedia at freebsd.org

Explain that you've got 2 sound chips with the snd_hda driver binding
to both & ask whether it's possible to get sound out of that
configuration without disabling one.

Sorry, I couldn't be more help.

BTW, hope you don't mind but I've cc'd this to multimedia@
