Thumbs up Headphones not working on ATI chip sound Laptop * SOLVED *

My laptop has ATI IXP SB4x0 High Definition Audio and I can get sound with built-in speakers but when I try plug the headphones its not working... in Alsamixer headphones is checked...

00:14.2 Audio device: ATI Technologies Inc IXP SB4x0 High Definition Audio Controller (rev 01)

here is my modprobe.conf

# ALSA portion
alias char-major-116 snd
alias snd-card-0 snd-hda-intel

# module options should go here
options snd-card-0 index=0
options snd-hda-intel index=0 model=lenovo

# OSS/Free portion
alias char-major-14 soundcore
alias sound-slot-0 snd-card-0
# card #1
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss

In volume control HDA ATI SB used and in switches section headphones selected.I use model=lenovo because i cant get sound working without that...Maybe something wrong..I attached alsa mixer pics..

MY system is F9 i386 with latest updates pulse audio installed.

Solution Here is what I did ;

First I changed model to 3stack-dig(coz I`ve ALC-861-VD codec chip) in modprobe.conf ( model=3stack-dig) then I put "<sound>=/dev/dsp* /dev/snd/*" and " <console> 0666 <sound> 0600 root " to the perm defs in the file /etc/security/console.perms.d/50-default.perms saved exit.Now headphones working
