This one works :
http://www.osx86.net/view/3371-applehda.kext_for_idt_92hd81b1x5.html
with this kext I have sound and the audio icon on menu bar,but as I said previously when I increase or decrease or even when a sound is playing,the light of mute button on my keyboard turns on,and also my audio input and output ports doesn't work.
My laptop is HP Pavilion dv6-6050se,and I use chimera 1.11.1 boot loader (for your information).
I attached my codec_dump.txt extracted from linux (just in case!)
BTW,I really appreciate your help!
