Then compile, 1 error ( Name already exists in scope (_DSM) )

The edit adds layout-id injection using Method (_DSM) to Device (HDEF). Your native dsdt has _DSM injection for HDEF. The fix is to deleted the native instance of _DSM.

Thanks toleda that did it Have HDMI audio working! I appreciate your help

 

[dellusergermany]

can someone confirm that those patches will also run on Intel HD 4400?

Thanks

 

[madman1234]

Looks correct. If you installed the latest Nvid1a web driver (343.02.01f1), HDMI audio is broken.
Install the previous version (343.01.02f1)

Can you please highlight this on the fist page? I replaced my GTX card and I spent a lot of time to figure out, why HDMI Audio is broken using HDMI on my GTX 660 TI. It worked only with my HD4000 onboard card.

After the downgrade of the NVIDA driver all is good

Thanks!

HD400 Graphics must be recognized and enabled.
Mobile HD4400, yes
Desktop HD4400, no

This guide supports OS X releases. Suggest a new thread or a post to the Nvidia Web driver thread, NVIDIA Releases Alternate Graphics Drivers for 10.10.1 (343.01.02)

Good day! Please help make the sound. Say what data are needed. I will write to you, for a month I can not make a sound. When trying to run with the flag kext-dev-mode = 1 computer continuously restarts. (Sorry for my bad english, I'm from Russia, I write to you through Google translator)
