Please, if you are still having issues, test with the latest development
release of Ubuntu.  ISO CD images are available from
http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you run the following command from a
Terminal (Applications->Accessories->Terminal). It will automatically
gather and attach updated debug information to this report.

apport-collect -p alsa-base 337314

Also, if you could test the latest upstream kernel available that would
be great. It will allow additional upstream developers to examine the
issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds .

Once you've tested the upstream kernel, please remove the 'needs-
upstream-testing' tag. This can be done by clicking on the yellow pencil
icon next to the tag located at the bottom of the bug description and
deleting the 'needs-upstream-testing' text.

Please let us know your results.

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.
