Try the steps here love2us: ZV6000 Audio x64 solved These are the steps that I took to get audio working on my HP Pavilion zv6000, and another user for his HP Pavilion zd8000, so it is a pretty universal solution for ac'97 on win7 x64. (It is universal since the zv6000 is an AMD desktop-cpu-in-a-laptop platform with conexant ac'97 and the zd8000 is mobile P4 with intel IHC6 ac'97, so chances are you will fall somewhere in that range of configs )
hope that helps, let us know results. make sure to use the poll on ZV6000 Audio x64 solved as well
