Ya that's the weird part. I was using chimera (chameleon, stolen and rebranded) as a bootloader at that time and I just loaded up the kext for the UX series laptops and right away I noticed that the Mute, and volume Up and Down shortcuts were working great with the OS X animation !
I then changed the bootloader to Clover and edited my DSDT in order to get the other keys working and all of a sudden none of the FN key combinations work anymore.. Is there any way I can debug this ?
I mean DSDT edits or not, the Volume Fn shortcuts should still work, no ?
Thank you for your help,
Adi
