I am trying to install Yosemite on my Acer Aspire E1-570 

i5 

500gb HDD

HD 4000 

12GB RAM 

ALC 3225 Audio 

 

I have been frantically trying for nearly a month to get audio working but I still cant find anything that works. 

I have been using RehabMans methods but it still doesn't work. banghead.gifbanghead.gif. When I boot a loud beeping sound occurs which seems to be linked to the Microphone as when I blow into the Mic it gets louder . 

Is there a kext to disable the Microphone?? so that this doesn't occur. 

Is there any methods which are simple and easy and that work. 
Kexts would be helpful thankyou!

Would a USB Audio Adapter Help but I still want to use laptops internal speakers.
