Here is "fixed" AppleHDA for Lion.
thank you very much for this.
If it won't help I can try to 1) unpair speakers-headphones in sound config - easy fix 2) try to change something else in config - needs deeper analysis
I've seen that you added a "Platforms.xml" to the resources-directory, unfortunately it does not change anything either.
What do you mean with "unpair speakers-headphones in sound config" and how is it done?
If I go to the Audio-Preferences, I see on the "Output"-tab, that I have "Name: Internal Speakers, Typ: Integriert" (funny it's mixed German and English language), if I plug in my headphones, it changes to "Name: Headphones, Typ: Integriert" and the audio is played.
On the "Input"-tab I have "Line In" (not tested) and "Internal microphone" which is working if I select it.
On my old T60 with SL I had running the VoodooHDA, but I had several problems with it, like KPs and non-working audio after resume, so I do not want to try this again.
Does it make any difference that I am using the latest 1.44 BIOS on my T410, would it make sense to downgrade to your patched 1.43-version?
Is there a way to get audio working without patching the AppleHDA and just changing the DSDT for the laptop?
PS: "I've installed Lion on my T410 i7 with NVidia/256 and it works mostly perfect. Lion is 10.7.5 and BIOS is updated to the latest original-lenovo 1.44."
