HD4600 HDMI audio + ALC887, is it possible?

Now I'm installed Yosemite on another PC.
But now I got another problem.

Is it possible to make HDMI and Legacy audio works at the same time?

Here is the spec:

CPU: Intel Core i5 4460 /w Intel Graphic HD4600
MB: ASUS B85M-G
On-board Audio: Realtek ALC887

Now I installed ALC887's AppleHDA with Audio Inject=1, and legacy audio works.
But HD4600 can't find any HDMI audio output after I added DSDT.
I guess maybe the problem is layout-id conflict.

And the attachment is my DSDT.

I need this because sometimes I have to plug on TV.
Thanks for help first.

Layout-id is not problem.
dsdt is not native. edits do not support HD4600 HDMI audio
Start over with native dsdt
See Post #1, HDMI Audio AppleHDA for HD4600 HDMI audio edits. Post to that thread for additional help.
