Hi,

I have installed mac os using the retail DVD(snowleopard_10a4_32_userdvd.dmg), everything is installed nicely but there is one small problem. THere is no sound.

 

My MotherBoard is Gigabyte g31-ES2L. the audio codec is ALC883. here is a full lspci output:-

I searched found multiple options suggesting LegacyALC883.kext, Voodo, something metioned about DSDT. I was following this guide but got confused at the generating own DSDT part.

 

Can anyone help how to get sound working on my hardware?
