Hello guys,

    I have just successfully installed Big Sur for the first time without any external help on a quite old laptop.
    Before installing macOS I saw on Windows its audio is a "7 series/C216 Chipset Family High Definition Audio", but on macOS the audio is not working.
    Does anyone know which ALCID I should use for it?

    Thanks in advance,

        Valentín

It's impossible to answer your question which is the same as asking how long a piece of string is...

Jake gave you a couple of methods to identify your codec, failing that, you may try and install VoodooHDA/AppleHDADisabler kexts through the method described here and check your codec id with apps such as DPCIManager.

Thank you both for your help!
I have two partitions and on the second one I have Windows.

On the attached picture you can see what I found under Hardware ID. Does this give you a hint on which ALCID I should use on the bootargs?

Thank you!
