wow, awesome. Can I ask a question? I have a P750DM with 8th core. I only modified the 0899 to 0892. With the Windows universal driver, I plug the earphone with mic into the optical. Windows think of it as a speaker. first, I think headphone and mic is ok. It wasn’t long before I noticed a series of damage to my headphones. And all the left earphones are silent. The headset doesn’t break immediately. What do you think of this? I can repay you for this.

Hi ! Did you ever try the new flavor of Realtek audio driver ? You probably know than Realtek have made 2 Way now : HDA and UAD.

if you try the UAD, did you have always the same problem / different result ?

Regards, Ray


I test it for whole day.
Realtek control panel show correct jacks and when I insert headphone , it report me that headphone inserted.
But there is no sound.I must edit Registry manually to get sound output.So weird.
Seems driver don’t change the value of proper Registry keys.
@Mov AX, 0xDEAD any ideas about this problem?

Hi :0)

Link seem to be dead

D 大, what is the final result of audio migration? I recently received a Lenovo IB250MH and transplanted it to Lenovo IB365MH.

Everything else is fine, but the audio issue cannot be resolved.

Hello, is there any chance to get my hands on your working bios? I found online one bios that has audio problem. The laptop that i flashed is p751dm-g. I want to upgrade it to coffelake because I have moded quadro p4000 inside. I would upload the bios file but I am fresh on this forum so I can’t still upload.

@veiu0107
try this bios, flash via spi programmer.

i give up the audio mod, because i mod clevo official skl bios to support kbl/cfl.

Thank you. I will try it and let you know. :slight_smile:

Hello, I tested it and it works. Thank you a lot. Windows automaticly loads the driver for quadro and it works with i7 8700k cpu.
