snd_hda: ALC888/1200 and mixer empty

[martinko]

Hallo,

I've got issues with snd_hda(4) driver.  According to Windows driver 
I've got Realtek ALC1200 but FreeBSD says it's ALC888.  mixer(8) doesn't 
show any devices and applications complain about it.  However, if I just 
cat sth.wav > /dev/dsp I can hear a sound/noise.  The listing follows.. 
  Please note that I changed default output to digital optical (Toslink).
