No Audio, cannot identify which ALCXXX do I have

[david.5]

I cannot identify which ALCXXX do I have and the audio isn't working. I haven't installed any kexts for audio yet.
There are two pictures: the first one is from my computer and the second one is from here: http://www.tonymacx86.com/general-help/107586-dpcimanager-1-5-release.html
and it shows that you need a kext to display Codec ID, Name and Revison.

DPCIManager does not see a codec. Verify BIOS/HD Audio enabled.

 

[david.5]

I don't have that setting in BIOS

 

[david.5]

So I did this...
and it worked!
Now, I just need help getting the audio working...

Your choices are Voodoo or Google Search: alc272 applehda

just use voodooHDA 2.7.2 i think i had that same codec on a laptop once and couldn't get it working using any kext i could find searching google and decided to give voodooHDA a try and Bham it worked and i wasted days before giving it a shot

 

[david.5]

no, it just said that kext was installed improperly and extension cannot be used.
So, yeah, the audio is still not working.

 

[david.5]

can anyone help me??

This is a really.... really... REALLY... LONG shot, but still:

Since you're on a laptop - laptops have either hardware switch or key-combination for audio and screen brightness. Lenovo Y570 (if memory serves) has a touch-based Volume/Mute band that you controll by touching it with your finger... and sliding for volume control.. yes? Is this your laptop?



Are you sure your audio isn't simply muted? (It might not work inside OSX, but should work when computer is booting)
