Hi,

The problem is not a kernel problem. There is an alsa ctl called "Line
Out" that controls the fact that the line outs are powered on. By
default they are. As I removed some obsolete ctls and created new ones
in the update, the name/number association changed. This confused
alsactl. It probably tried to restore the stored value even if the ctl
name had changed (passthru defaulted to 0 IIRC), thus muting the line
outs. The driver should work with both kernels. You can change the value
of the Line Out ctl with amixer, and then regenerate
your /etc/asound.state file.
