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. . 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.
