Please elaborate, I have no idea what you mean.
 
sound and mic was work proprely ,after my system crash i turn off my box ,while later i turn it on and then i run skype ,i notice i can't hear voice call so thought it simple problem so i type mixer in CLI to see problem ,so i see only vol and pcm .
 
Code: 
FreeBSD Audio Driver (newpcm: 64bit 2009061500/amd64)
Installed devices:
pcm0: <HDA ATI RS690/780 HDMI PCM #0 HDMI> (play) default
pcm1: <HDA Realtek ALC888 PCM #0 Analog> (play/rec)
pcm2: <HDA Realtek ALC888 PCM #1 Analog> (play/rec)
pcm3: <HDA Realtek ALC888 PCM #2 Digital> (play/rec)
 
Well, as you can hopefully see, your default sound device (pcm0) is the HDMI audio chip on your ATI GPU. Assuming you want to use pcm1, you would set the hw.snd.default_unit sysctl to 1.

i thing i enabled HDMI audio option from setup after system crash ,that is why pcm0 is now default HDMI audio .
i get this :
Code: 
%sysctl hw_snd_default_unit=1
%sysctl: unknown oid 'hw_snd_default_unit'
