Hi, don't know if this is the right place to post:

I got a MacBook (late 2006, C2D) and have no sound when running Xubuntu
9.04 beta. I ran the script mentioned above the report sent to
http://www.alsa-
project.org/db/?f=19ad60fa195ed8bc8e08c903cc6d9490b426d20c

Thank you.

Bug description:
Reporting this bug for another user...

In MacBook and MacBookPro 5,1 (aluminium, late 2008) the soundcard works out of the box only with headphones, and to turn speakers on it is necessary to manually set the 6 channels. In that case, sound is heard both on headphones and right and center speaker; the left speaker doesn't work yet.

This bug is confirmed by several users, see the additional information attached.
