Also, you can try to copy sound/pci/hda/patch_analog.c from 2.6.33 to 2.6.34 to check whether it works. There shouldn't be many changes in that file. thanks, Takashi _______________________________________________ linux-pm mailing list linux-pm@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/linux-pm
