I am having the problem with Jaunty. I just upgraded from the 2.6.28-12 to 2.6.28-13 kernel and sound does not work. Here is the error from sudo invoke-rc.d alsa-utils restart: * Shutting down ALSA... [ OK ] * Setting up ALSA... * warning: 'alsactl restore' failed with error message 'alsactl: set_control:1400: Cannot write control '2:0:0:Four Channel Mode:0' : Operation not permitted'... Invalid card number.
