Sound doesn't work on the speakers but only on the headphones of my Macbook Pro. I've heard that upgrading ALSA from 1.0.12 to 1.0.13 fixes this problem. Please consider upgrading the packages soon.
How-to & packages are here: http://people.redhat.com/stransky/alsa/ alsa-drivers are updated with kernel so I'll release packages after that.
alsa-drivers-1.0.13 is included in a new kernel update.
Maybe an alsa 1.0.13 packages push for updates-testing should be The Right Thing™ to do at this point. Kernel 2.6.19 with alsa 1.0.13 is already in updates-testing, so the updates-testing user could do futher testing before updates release. My 0.02 $. Thks.
done.
