Installation of FreeBSD 10.0-ALPHA1 on iMac 11,1 was successful but I have problem with sound settings.

cat /dev/sndstat
Installed devices:
pcm0: <ATI R6xx (HDMI)> (play)
pcm1: <Cirrus Logic CS4206 (Internal Analog 4.0/2.0)> (play/rec) default
pcm2: <Cirrus Logic CS4206 (Rear Analog)> (play/rec)
pcm3: <Cirrus Logic CS4206 (Rear Digital)> (play/rec)

If I use hw.snd.default_unit=2 I get sound in headphones but not internal speaker and microphhone doesn't work. Other unit don't work.

I use boot-verbose and I got:
