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. Thomas
