No HDMI audio on Intel HD4000 (Intel i7-3770, ASRock H77M-ITX mainboard)

[CBorg]

Dear all,

since I updated my system to Sierra using Clover as bootloader, HDMI audio is no longer working. Analog audio of the ALC892 codec is working, but no HDMI audio device is detected. A detailed description of my hardware configuration can be found here: https://www.tonymacx86.com/threads/...0-asrock-h77m-itx-mountain-lion-10-8-1.69575/

When I'm executing Toleda's audio_CloverHDMI script as described in https://www.tonymacx86.com/threads/new-automatic-hdmi-audio-script-released.184867/ I get the following error message:

What can I do to solve this merge issue? Or is there something else wrong?


Kind regards,
