Hello, I have been testing and I have not managed to make the audio work, even following the tutorial perfectly.


I think my problem is in the config.plist, since before I used to work the audio in a vanilla way.


Could you check my config.plist to see what is happening?

I had to use this config.plist to make the hd4400 graphics work


thanks friend :)

@MAldon- I have tried all the layout. when I record voice memos, I am able to hear very faint noise from it , it seems like the gain of internal microphone is too low. Is there any way that it can be increased? And also, will you be able to help in multitouch gestures for ELAN1010 touchpad?

I tried all layouts and so but all it does it load applealc and nothing for codec and no devices show up in audiopreferencies.

Seems it doesnt load codec. The computer is Lenovo thinkstation S30 with C602J chipset and Xeon 1620V2, AMD Vega56 and ALC662 V3 soundcard. I can see some values inserted in ioreg but still not loading codec.

Used X79 Olarila Clover. Added the DSDT and rebooted a few times. Seems computer runs a bit smoother but Audio still not recognised so I tried all the alcid=x as bootargument. But still no audio device on any.


Used this list: https://github.com/acidanthera/AppleALC/tree/master/Resources/ALC662


Btw, computer complains about power to USB-port even when an USB-stick is put in. If I put an USB-hub in between it doesn't. How can I fix this?
