none18 Posted December 13, 2014 Share Posted December 13, 2014 Hi, I am trying to solve my audio problems on Toshiba Satellite c55-a-1h9. I read about it everywhere, but their solutions seems to not work here. My audio codec isn't typical its: IDT 92HD95 (ALC269Q) I already got patched AppleHDA kext for this audio, but right now I have to inject this code into my DSDT to HDEF section: Method (_DSM, 4, NotSerialized) { Store (Package (0x04) { "layout-id", Buffer (0x04) { 0x0C, 0x00, 0x00, 0x00 }, "PinConfigurations", Buffer (Zero) {} }, Local0) DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0)) Return (Local0) } } and here I am having huge problems. I've generated my clean DSDT using Clover Bootloader menu (F4), I am opening this using MaciASL, next I am adding this code into section, but I can't compile it because errors that occours. I am novice at DSDT, and I just thought that someone with knowledge about it could help me here. I am including my "clean" DSDT and Patched AppleHDA, also I am adding CodecDump. If You need anything more, please let me know. Sorry for my English.

none18 Posted December 13, 2014 Author Share Posted December 13, 2014 I have to inject port ID: 12 in my clover audio section? or You mean I should now rechange my AppleHDA with this ID ? OK, I've put the DSDT.aml file inside my EFI / CLOVER / ACPI / PATCHED I've changed the ID to 12 inside AppleHDA.kext and I put it inside EFI / CLOVER / KEXTS / 10.10 and as well I used Kext Wizard to install this kext in S / L / E, next I rebuilded caches and fixed permissions, but I still don't hear sound. There is no audio device detected. What I am doing wrong?
