Hi,
Since upgrade to Karmic (I think near RC stage) I lost sound in built-in speakers. Desperately I dd'ed my partitions on HD and made fresh install of Karmic: still no sound. However I can hear sound through headphones jack, and it's clear, loud and of good quality.
My chipset is:
00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 01)
