Audio and dimming are not working

[Toyide]

Thank you for your code sharing!

I have a 15-5547(i7-4510u) as well, I try those file and it works well. The HD4400 can be boosted after disable "drop all OEM tables".

However, the problem is the audio not working. just wondering if u know where is the problem.

"NOTE: Once you modify your settings in BIOS(especially Graphics Configuration in SA), you have to remove previous ACPI tables first, redump ACPI tables by press Fn+F4/F4 under Clover, and run deploy.sh again to patch your ACPI tables again."

By the way, I skiped this step, maybe it occurs problem? I am cuffesed to find the ACPI tables, are they in Clover or? also having trouble find the file "deploy.sh"

It's there something I missed? please let me know. Thanks in advance!

Hi @Toyide , the 15-5547 is my friend's laptop. I help him to install OS X(10.11.x) within just one night. Thus time for me to refine the whole 15-5547 is very very limited.

What's not working:

• Sleep(you need to switch to hibernate instead)
• Audio you should use VoodooHDA to achieve the best result

As you mention audio issue, yes, I've tried AppleALC at that time, but the codec resource just failed to power up the audio on this laptop. VoodooHDA is good, but cannot auto switch headphone and external speaker. The only best solution (IMO) is asked for an audio expert(like Mirone) to build an AppleHDA for your laptop. That will also solve the headphone/ext speaker auto switch issue.

Tell me if you have any other questions about this laptop.

Thank you so much! @syscl I updated to the newest version(10.12.2), and it still working. Nice job! Just wondering the Brilliance control is working on your friends laptop? Thanks!
