Can you explain me how to do it?

It's explained in the OP of this topic and there's a link to a more detailed example viewtopic.php?f=18&t=604

For example, if your config is
Code: Select all
nid 17 0x0221401f as 3 seq 0 Headphones Jack jack 1 loc 2 color Green misc 0
nid 18 0x01014010 as 1 seq 0 Line-out Jack jack 1 loc 1 color Green misc 0


change to
Code: Select all
nid 17 0x02214050 as 3 seq 0 Headphones Jack jack 1 loc 2 color Green misc 0
nid 18 0x01014010 as 1 seq 0 Line-out Jack jack 1 loc 1 color Green misc 0

(default association 5 must not be used by other node, use first unused number)

When i use the (latest) VoodooHDA in this topic my laptop (Asus N53SV-SZ404V) my speakers looks like they gonna explode. A very hard noise. So i have to shutdown the laptop immediatly.

I also used a older version of VoodooHDA but i didn't had a prefpane with that one. The sound was not working with this older one so i want to try the prefpane settings in first post. That's why i want to try this version.

Do i have to patch my DSDT.aml for the sound? Or do i have to use an older VoodooHDA with prefpane? I patched my DSDT with DTGP, EHCI and IRQS.

Read about audio feedback in the first post.

You mean:
Problem: audio feedback (Larsen effect), sound loop between input (microphone) and output (speakers).
Solution: mute iGain and increase iMix or Mic if microphone doesn't work


It's a very loud sound so could it be the larsen effect? If yes, edit this in Info.plist right? I have to reinstall Lion or can i boot without starting the VoodooHDA.kext?

Yes, that's it (I guess).

Boot in single user mode, remove kext, then install the edited kext.

Boot with -s
Code: Select all
mount -uw /
rm -r /System/Library/Extensions/VoodooHDA.kext
reboot


You can also play with iGain/iMix values in the prefPane.

Run editor with sudo or copy kext to desktop, edit and install it again.

Remember to repair permissions and update cache (or use a tool like Kext Wizard to install).
