Hi stephane any chance you can run DCPIManager to get a listing of the hardware, as it will tell you the audio codec, most of the ALC codecs can be made to work using appleHDA and some ACPI patching. and also help out myself by letting me know if this machine can be made to work 100% with a change of wireless card being all that is required. If it can't i will have top do further research on a model of laptop that can be made to work, and is currently available to buy new. if not ill just opt for a acer switch alpha 12 and stick to windows 10.. it has a far higher res screen for around the same money.
