Is there something special that a person should do to get the  
Microphone to work with an HDA audio controler?

Laptop speakers sound normal but the mixer only has output and not  
input.  Volume works, etc.

I am using the snd_hda kernel module on an Acer 5520/5679 laptop with  
the following
general info:

from dmesg:
pcm0: <NVidia MCP67 High Definition Audio Controller> mem  
0xf2680000-0xf2683fff irq 21 at
device 7.0 on pci0
pcm0: [ITHREAD]
pcm0: <HDA Codec: Realtek ALC268>

 From pciconf -lv :
pcm0@pci0:0:7:0:        class=0x040300 card=0x01261025 chip=0x055c10de  
rev=0xa1 hdr=0x00
     vendor     = 'Nvidia Corp'
     class      = multimedia

uname -a:
  # uname -a
FreeBSD local15.local.net.mx 8.0-CURRENT FreeBSD 8.0-CURRENT #13: Thu

root@local15.local.net.mx:/usr/obj/usr/src/sys/ENCONTACTO  amd64

Any suggestions for getting the Microphone working would be greatly  
appreciated.
