Audio problem at 10.11 GM

[rchen29]

Hi all

I recently updated to 10.11 GM. Everything working fine. Except my audio in 10.11 is not working.
I have a Sony Vpcse190x laptop which have ALC275 loaded. The old kext from Yosemite alc275codec.kext not work any more. Any one have same situation or some ideas?

Moreover, I have HD3000 video card. But I suffered a glitch everything time boot into the system. Here is my EFI partition.

Extra patch required. Must also zero out 0x1983 just like 0x1984.

Hi
Rehabman, thanks for your reply. But, I'm confused at how will you set these number to zero?
