Bug Description
Binary package hint: alsa-base
The latest macbooks using Intel/Nvidia HD sound will not work with this driver version 1.0.20 for 'snd_hda_intel'.
The drivers will load and the mods will be recognized but there will be no sound.
The latest macbooks need the alsa-driver version 1.0.21 installed to have sound working. This is even documented on Ubuntu's own Wiki.
I hope the Ubuntu team will update Karmic to the alsa-driver version of 1.0.21 before Karmic goes final.
THANK YOU

It is true, and affecting also Macbooks Pro 5,3.
You can always build it from source from wget ftp://ftp. kernel. org/pub/ linux/kernel/ people/ tiwai/snapshot/ alsa-driver- unstable- snapshot. tar.gz but that is not a good solution for most users.
Furthermore, since the elimination of the linux-restricte d-modules package I haven't been able to make it work again.
