Hi,

I installed EI Capitan in my ASUS GL551JM. It has Realtek ALC668 audio chip and I patched the AppleHDA to make the speaker and headphone work. However, when I installed Realtek HD Driver in my Windows 10 and reboot to EI Capitan, no sound from the speaker (headphone working).
I tried to find the solutions. There are two ways to resolve the problem.
First is to remove the Realtek HD Audio Driver and use Windows Driver, but the windows driver has many bugs.
Second is to make a cold boot (shut down from windows and boot to ei capitan).
Is there a way to have speaker sound without removing Realtek Driver and cold boot?
(I have installed CodecCommander)

Thanks.

Try config.plist/Devices/Audio/ResetHDA=true.
 
Hi,
I tried your approach but it doesn't work.
I searched for the alike issues at Google, and I used ubuntu to check the hda-verb one by one. Finally I found where the problem from.
The Realtek Driver in Windows will do something with the HDA COEF and make it wrong(don't know why). After reboot from windows to other OS(Linux, OS X), due to the wrong COEF, the speaker has no sound.
The correct COEF for 0x07 register is 0x0f80, but the Realtek Driver will change it to 0x2f80.
To solve the problem I add this code in CodecCommander.

Note that you can do custom configurations for CodecCommander with ACPI. Refer to the SSDT-ALC283.dsl example.

It will make updates to CodecCommander easier for you.

Could u tell me how you did this? Your code doesn't apply to my ALC295 and I wanna find out where my problem lies. Many thanks!

What issue are you trying to solve?

Note that questions regarding ALC295 in a thread clearly marked "ALC668" are obviously off-topic.
Open a separate thread for your issue.

No "Problem Reporting" files attached.
Read FAQ, "Problem Reporting" again. Carefully. Attach all requested files/output.
