Public bug reported:
There is no sound device on my macbook pro (13,3", version 5,5) when booting
into the latest 2.6.31-18 kernel on Karmic 9.10 64bit. If I go to System ->
Preferences -> Sound -> (Tab) Hardware
no device are listed.
This problem does not occur if I boot into the 2.6.31-17 kernel (after
booting into -18 I have to select the right device again and use the
right settings in the alsa mixer but other than that everything works
fine).
Please let me know if I can provide any more info.
thank you
Paul
