GA-P35-DS3 ALC889a / ALC885?

[Anders1]

ATM I use the following DSDT patch, however the outputs are all wrong (line out, line out, line out) and it's very noisy. It sounds kinda like a bad front panel, with electronic noise...

 

I've looked everywhere for a proper DSDT for ALC889a in combination with GA-P35-DS3 but haven't so far managed to find anything. I have a Linux codec dump (apparently ALC885 is quite close to ALC889a, and it is what Linux recognises it as) if that's of any use.

 

I hear it's possible to make this work with no modified Apple drivers, but so far haven't been able to. I don't use LegacyHDA or anything like that (never helped anyway).

I've got it working on my EP35 DS3P. I just added an ALC889a.kext file to E\E folder and rebooted and audio is working.

Thank you, it works now.

 

I installed ALC889a.kext to S/L/E and various Legacy (3 of them) to S/L/E/AppleHDA/Plugins, and sound is great now.

 

I have a pinconfigurations DSDT here for anyone who wants to use it (the outputs are all correct I think)
