Get the Ubuntu source code for the package that owns that ALSA driver, find the place in the driver's initialization code where ac97_quirk=7 is handled, then check the driver's suspend and resume callbacks and make sure the suspend callback is correctly saving the LED state and that the resume callback is re-initializing the LED from the saved state in the same way the init code does. grep and printk() are your friends ;-) HTH, Lee _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
