Sorry for posting on an old thread.. but. I have a brand new P8P67 who's back green audio jack is not working. It will only output out of one channel. I can sometimes get two channels by wiggling the jack a little bit. The front audio jack works fine. So, I'm also trying to re-task other back jacks that I don't use to the front-speakers.
I do not have the registry key that you are referring to in this email. I am running 126.96.36.19935 of the RealTek drivers (newest from Asus' website). Instead, I have found some "Pin0x" keys in:
I changed all of the Pin01-Pin0X values to 04 as indicated in this thread, but I still can't get front speaker output from any of the jacks.
Does anyone have a suggestion?
