No Audio device P5G41T-M LX - ALC887VD

[glofter1]

Hi friend. I was very hard situation, all ready 4 days I can not resolve this problem with audio on old mainboard P5G41T-M LX.
Chipset is ALC887VD.
So with DPCIManager system are recognize only AUDIO device 0x808627D8 and sub device 0x1043840B
I try to make download dsdt from ubuntu and patch via https://github.com/toleda/audio_ALCInjection/blob/master/[Guide]-Add_or_Edit_HDEF-dsdt.pdf
this GUIDE but no success.
So I found one DSDT and wen I put in EFI system are boot with recognize ALC888b, but no other PIC device found USBhub, network.
I attach my original DSDT from ubuntu and other DSDT.
can some one tell me what should do to find solution ?

After lot of reading I just active ALC887 in DPCIManager, but it recognize like 888B is this right ?
so I add this patch to original DSDT from UBUNTU.
I attach patched DSDT.
but after that VOODOO audio not work, also toleda patch not work for me I try all 1,2, and 3 ID but no success.

I try everything, SO at the end I start audio with fresh install Sierra I patched DSDT and use multibeast to add audio 887 legacy.
and system are recognize audio. It show on desktop I can slide volume up/down and I can change input/output device but from sound system not coming any sound. I try and other things and after that I delete every audio patch and install voodoohda 2.8.8. now I can play music but sound like bus station

I try with audio ID = 1 , 2 and 3 but no success
