Alc662 not working in Mountain Lion

[Lissol]

Hi. I know its old but I connect my first old disc with 10.8.5 and try to do Lilu+Alc as in Mojave and HS. Always no devices found.

Reading a lot, I suspect about the ML kernel (12.6). I think the min Kernel for Alc662 is 13 . Is that right? Could that be solved?

  Thanks.

It could be an IRQ conflict issue on the HPET Device.
If you use Clover, try setting FixHPET, FicRTC, FixIPIC and FixTMR to True in ACPI - DSDT - Fixes.

Hi:

Thanks shl628. I´ll try.

I tell about Kernel issue because I found a little peace of AlC662 code. And I don't see anything about Kernel12. Sorry I don´t understand coding. But it seems to me Patches to all kernels, 12 not: ( Maybe its imposible to work).Sorry if not.

It seems that the only solution to use AppleALC for ALC662 in 10.8 is to modify the code itself.

Thanks to all.
