Unable to patch ALC889 #14

Closed CyCLoBoT closed 9 years ago

CyCLoBoT commented 9 years ago

When I try to patch Realtek ALC889 using the latest script, the first question asks me to confirm if I have Realtek ALC889. When I confirm, the next line says that Audio ID: 889 is not supported. I had used an earlier version of the script successfully and nothing has changed in my system.

I am running OSX 10.10 (Yosemite).

See README. Supported ALC889 Audio IDs are 1, 2 or 3. Determine what (dsdt, enabler, etc.) is injecting layout-id: 0x79 0x03, 0x00, 0x00 and edit/remove. If you answer yes, the script will run. However, no audio until the incorrect injection is fixed.

Sorry toleda, I'm not too sure on how to check this. Currently I'm using a patched ALC889 and ALC889Enabler just so I can get sound. Prior to this, I had used an earlier version of your script with just the stock AppleHDA.kext and it worked perfectly. I have not made and changes to my DSDT file either.

I have gotten it to work. I had to recheck FixHDA and Drop OEM_DSM box in Clover Configurator.

toleda, I have noticed that if I play any audio/video file, I hear a popping noise in speakers just before the audio starts. I have changed speakers to ensure it's not the speakers that's an issue. Any idea on what could be causing this?

After a period of no audio, amp power is set to minimum (quieting). When audio resumes, the amp is powered up causing a pop on some systems. Solutions: 1. digital audio (usb, cdmi, etc.), 2. MacPro3,1 or 3. Google search "mac antipop".
