Well guys still having probs with sound. I have tried all recommendtions.

This is the outpit of my /dev/sndstat

cat /dev/sndstat
FreeBSD Audio Driver (newpcm)
Installed devices:
pcm0: <Intel ICH4 (82801DB)> at io 0xc000, 0xc400 irq 17 bufsz 16384 (1p/1r/0v 
channels duplex default)

Keep in mind that I do have snd_driver loaded in /boot/loader.conf even 
snd_ich for overkill

Output of loader.conf 
nvidia_load="YES"
hw.ata.atapi_dma="1"
linux_load="YES"
snd_driver_load="YES"
snd_ich_load="YES"

Can anyone explain why i do not have a driver associated with card 
in /dev/sndstat. Also, every one out of 50 reboots, I will get sound for 2 
seconds then it dies.

This is my pciconfig

pcm0 at pci0:31:5: class=0x040100 card=0x4941434d chip=0x24c58086 rev=0x02 
hdr=0x00
    vendor   = 'Intel Corporation'
    device   = '82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) AC'97 Audio Controller'
    class    = multimedia
    subclass = audio

Thanks for the assistance
