If you don't even have a proper PCI list, the sound module never even gets called. Reassigning to Linux.

I'm not seeing an Audio controller listed in the lspci output. Are you sure this system has a sound card? Has it maybe been disconnected? Did this system have sound in the past? If so, which release? If it did have sound in the past, could you run the following command from the working release:

apport-collect -p alsa-driver 629732

Since its a laptop I doubt the sound card would just be disconnected. I will try to get the sound working on previous versions and to make sure that there is no hardware issue.

After a lot of testing I'm quite sure this is a hardware issue now so I'm marking as invalid.
