snd_hda silent

[Michael W. Lucas]

Hi,

I'm running on i386 -current, built 5 April 2007, on a Toshiba P105.
FreeBSD recognizes the sound card, but my speakers are silent.

Unfortunately, this laptop does not have a serial port.  It panics on
a verbose boot.  I'm delighted to provide a verbose dmesg if anyone
can suggest a way to get one. : -(

Any suggestions, folks?
