HDMI audio does not work on LG Gram 17

Recommended Posts

Hi guys, I'm trying to setup audio on my LG Gram 17 (17z990, i7-8565, Whiskey Lake UHD620, CX8200). I'm using lilu/whatervergreen/applealc and everything works just fine. I have qe/ci/metal, all discrete audio inputs/outputs working, I also have hdmi video output working, but no hdmi audio. In windows it is working though. I even can't see hdmi audio controller in ioreg when I connect my tv to hdmi port. I tried to use voodoohda and with it I can see hdmi audio output device in ioreg, but it doesn't work. No sound is playing. I attached in separate files ioreg with voodoohda and with applealc as well as clover config, dsdt and some other supportive information. 

Thank you.

Try using only the patched DSDT, let's see what happens.

 

Btw, who have patched it for you?

Ok. I left only dsdt.aml in patched folder. Nothing has changed.

New send me file is attached.

dsdt I have patched by myself. There are only battery patch and I2C patches. Nothing else.

 

Thank you

This week it's very busy for me.

 

But maybe @MaLd0n have some idea about it ;)

May be.  The problem is that his last visit here was on 25.03.2019 May be you can ask him directly if he's willing to take a look at this case?
