If you have Windows install, you can run dxdiag.exe

From the exported text file, look under sound devices/Hardware ID

Or in Device Manager, select properties under sound and look under Hardware ID

There's any other way? I don't have windows installed on that laptop

One way would be to go visit your motherboard manufacturer site and look for the Audio information under the specification section.

Or boot from a live linux distro (like a ubuntu version that will boot from a USB key) and then open terminal and type:

 

cat /proc/asound/card0/codec#1 > ~/Desktop/codec_dump.txt

 

This will make a text file on the desktop with the information you're looking for in it.

Ok, so the result is this:

 

 

codec_dump0.txt

Can't see any indication of the codec in that dump. Some laptops (eg: Dell) actually list the codec model in BIOS settings. Check that out. Could help if you would specify the make and model of laptop of course...

 

Had you installed VoodooHDA + AppleHDADisabler kexts before running DPCIManager? The app won't show the codec without them.

Actually the codec dump you got is for the HDMI audio as stated in the first line of the codec_dump.txt.

What we would need is the codec dump for the audio card, so maybe it would be found by the same procedure (live ubuntu, terminal) but with card1 ...

 

cat /proc/asound/card1/codec# > ~/Desktop/codec_dump.txt

 

that would give us the right codec dump for your card.

or card1/codec#1 ... you have to try ... and keep faith ;-) 

 

P.S.: it can also be a combination of card and codec (ex card0/codec#0, card0/codec#2, or card1/codec#2) It is actually a directory in the linux os ... so in terminal = cd\  ,  then cd cat, cd proc, cd asound, then ls to see with card exist (it will be a directory), then cd cardx, and finally ls ... once you know with exist, replace card an codec numbers in cat /proc/asound/card1/codec# > ~/Desktop/codec_dump.txt

Thank You so much! Now it worked!

The command that i used was this

cat /proc/asound/card1/codec#0 > ~/Desktop/codec_dump1.txt

 

To boot with audio all i need to do it's add the arg: alcid=layoutid of the audio codec, right? (I use OpenCore)

 

codec_dump1.txt
